Can Genetics Stop the Screwworm?

The New World screwworm doesn’t simply feed on something that’s already dead. Its larvae invade wounds and feed on the living flesh of warm-blooded animals.

That disturbing fact is part of what made the parasite such a nightmare for American ranchers and wildlife managers before it was eradicated from the United States decades ago. Now, in 2026, New World screwworm has returned to the U.S. mainland, and the battle to stop it has taken on new urgency.

But what if one of the next weapons against this flesh-eating parasite isn’t simply more traps, treatments or sterile flies?

What if it’s genetics?

That’s the subject of Episode 80 of the Dark Outdoors podcast, featuring a conversation between Chester Moore and Matt James of Colossal Biosciences about the potential for advanced genetic technologies to become part of the fight against New World screwworm.

A New Kind of Weapon

For generations, one of the most effective weapons against New World screwworm has been the sterile insect technique.

Enormous numbers of sterile male flies are produced and released into areas where the parasite is present. Females that mate with those sterile males produce no viable offspring, allowing authorities to suppress the population.

It was an extraordinary biological weapon against an extraordinary parasite, and sterile insect releases remain central to the fight today.

But biotechnology has advanced dramatically since the original screwworm eradication campaign.

Colossal Biosciences has publicly discussed the potential for genetic biocontrol and gene-drive technology to be applied to New World screwworm. Instead of relying exclusively on repeated releases of sterile flies, advanced genetic techniques could potentially introduce traits designed to interfere with reproduction and spread those traits through a population.

That possibility is at the center of Moore’s conversation with James.

The discussion examines what these emerging technologies might mean, how genetics could potentially complement existing eradication methods and where the science could go from here.

Wildlife Could Pay the Price

This parasite is often discussed as a livestock problem, but cattle aren’t the only animals at risk.

New World screwworm can infest warm-blooded animals when female flies lay eggs in wounds. That puts wildlife in a particularly difficult position because wild animals can’t be routinely inspected the way livestock can.

A deer injured while fighting, a wild sheep wounded on the landscape or another animal suffering even a relatively small injury could potentially become infested.

The United States has already seen what screwworm can do to wildlife.

When New World screwworm appeared in the Florida Keys in 2016, endangered Key deer were hit hard. That outbreak remains an important warning about what can happen when the parasite reaches a vulnerable wildlife population.

The return of screwworm to the U.S. mainland makes the development of every effective control tool worth watching.

Genetics and the Future of Conservation

The larger question explored in Episode 80 goes beyond screwworm.

Modern biotechnology is creating possibilities for wildlife conservation that would have sounded like science fiction not long ago. Scientists are exploring genetics as a way to preserve endangered species, restore genetic diversity and address biological threats.

Screwworm turns that idea around.

Could some of the same rapidly advancing genetic technologies being considered to help wildlife also be used against an organism capable of devastating wildlife and livestock?

There are enormous scientific and ecological questions surrounding these technologies, and no single approach replaces the proven methods already being used against this parasite.

But the possibilities are fascinating.

The New World screwworm is back.

Could genetics help send it away again?

The Trail That Shouldn’t Be There: A Dark Warning in Remote Country

There are certain things you expect to find when you get deep into wild country. Game trails winding through timber are normal, as are tracks from hunters, hikers and fishermen in places where people have legitimate reasons to travel. An old logging road cutting through a forest or ATV tracks on public land aren’t automatically anything to worry about.

But sometimes the amount of human activity doesn’t match the location, and that’s when I start paying attention.

One of the most important outdoor safety lessons I can give anyone who spends time hiking, hunting, fishing, photographing wildlife or exploring remote country is to notice human sign that doesn’t make sense. If you’re miles from where you would expect much activity and suddenly encounter heavily worn footpaths, repeated tire or ATV tracks, unusual amounts of trash or makeshift camps in strange locations, don’t automatically assume you’ve discovered an interesting place to explore. There might be a perfectly innocent explanation, but sometimes the smartest move you can make outdoors is turning around.

I’ve learned that firsthand. Years ago, I was exploring an area when I began noticing things that didn’t fit. There was too much evidence of people for the location, and eventually I found out why. I had stumbled into an area associated with a meth lab.

That experience permanently changed the way I look at human sign in isolated places. Wildlife gets most of the attention when outdoor danger is discussed, but I’ve spent decades investigating dangerous wildlife encounters and strange situations in the woods, and some of the circumstances that concern me most involve people. A bear generally has a reason for what it does, and so does a venomous snake. A criminal who believes you’ve discovered something you weren’t supposed to see introduces an entirely different kind of danger.

When Human Sign Doesn’t Fit

People who learn tracking are usually taught to look for wildlife sign. Tracks, scat, rubs, beds and feeding activity can reveal an incredible amount about what animals are doing in an area, but I think outdoorsmen should learn to read human sign as well.

Context is everything. A well-used trail half a mile from a popular campground isn’t unusual, and tire tracks around a hunting lease during deer season aren’t mysterious. Beer cans around an easily accessible fishing hole might be disgusting, but they’re unfortunately not surprising. The situation changes when you’re deep in an isolated area where the amount or type of activity seems completely out of proportion with the surroundings.

Maybe you’re following an obscure trail and discover another path that looks far more heavily traveled than anything around it. Perhaps repeated vehicle tracks lead somewhere that doesn’t appear to have any recreational reason for traffic. You might find discarded supplies, unusual camps or other evidence suggesting people are spending substantial amounts of time in a place where you wouldn’t expect anyone to be.

None of those things automatically means criminal activity is occurring, and that’s important to remember. There can be perfectly innocent explanations for unusual activity in the woods, and you shouldn’t convince yourself that every piece of trash or tire track belongs to some criminal operation. At the same time, you aren’t obligated to satisfy your curiosity and find out what’s at the end of every strange trail.

That’s probably the biggest lesson I took from my own experience. When something doesn’t feel right, you don’t win anything by discovering exactly what’s happening.

You Don’t Need to Investigate

There is a natural tendency among outdoorsmen to explore. That’s part of why we’re out there in the first place. We want to know what’s over the next ridge, where an old logging road goes or what is around the next bend in a creek. I’ve built much of my career around that same curiosity.

But there are times when curiosity can get you into serious trouble.

If you encounter something that genuinely causes you to suspect illegal activity in a remote location, create distance and get out. You don’t need photographs, you don’t need to walk another hundred yards to see where the trail goes, and you certainly don’t need to confront anyone. Once you’re somewhere safe, authorities can determine whether what you saw deserves investigation.

Illegal activity in wild places isn’t limited to one thing. Over the years, law enforcement agencies have encountered clandestine drug operations, illegal marijuana grows, smuggling activity, stolen property and other criminal enterprises in isolated outdoor areas. Remote country provides exactly what criminals sometimes want: fewer witnesses and less chance of somebody accidentally wandering through.

The problem is that outdoorsmen do wander through. Hunters follow game, anglers explore creeks, wildlife photographers move off established routes looking for animals and hikers wonder where old trails lead. That sense of exploration is one of the things I love most about the outdoors, but it also means we can accidentally enter places where someone desperately doesn’t want visitors.

The Dark Side of Illegal Grows

Illegal growing operations provide a particularly disturbing example.

The marijuana landscape has changed dramatically in America, but legalization in various states did not make illegal grows disappear. Unauthorized cultivation has continued on public and private lands, and some operations have been associated with organized criminal activity. These sites can also have serious environmental consequences involving habitat destruction, trash, water diversion and chemicals that threaten wildlife and waterways.

For the person who accidentally discovers one, however, the immediate concern is much simpler: Who is protecting it?

I’ve collected frightening accounts involving people who encountered growing operations or suspicious activity in remote country. One of the areas that inevitably comes up in discussions of this subject is Northern California’s so-called “Murder Mountain” region, which became internationally known through the Netflix documentary series examining disappearances, crime and the underground marijuana economy surrounding Humboldt County.

One of the stories we’ve discussed through Dark Outdoors involves an encounter near that infamous region. Another account involved something that sounds like it came straight out of a horror movie—a trained dog being sent after a hiker who had discovered a growing area.

Think about how quickly the normal rules of outdoor safety change in that situation. You’re hiking through the woods, realize you’ve walked into someplace you probably shouldn’t be and suddenly your concern isn’t a mountain lion, bear or rattlesnake. It’s a dog being deliberately used against you by another human being.

That is an entirely different category of outdoor threat.

Sometimes People Are the Biggest Danger

A major part of what I do with Dark Outdoors involves examining the things that can go wrong beyond the pavement. Some of those stories involve wildlife, and I’ve investigated animal attacks and encounters with bears, sharks, big cats, venomous animals and other creatures capable of seriously injuring or killing a person.

I respect those threats, but wildlife behavior often has patterns we can learn. We can study bear behavior and understand circumstances that increase the potential for conflict. We can learn where venomous snakes are likely to be encountered. We can study how mountain lions hunt and what might cause one to behave unusually around people. Knowledge doesn’t eliminate danger, but it gives us tools for reducing risk.

Human beings are harder to predict.

Someone protecting an illegal operation might be frightened you’re going to report them. They might be under the influence of drugs. They might be armed, desperate, paranoid or violent, and you have no way of knowing what you’re dealing with.

That’s why recognizing the situation before you walk into the middle of it matters so much.

Read the Country Around You

I believe strongly in situational awareness outdoors. That means occasionally stopping and actually looking at what’s around you instead of moving constantly toward your destination.

Ask yourself what has changed. Are you suddenly seeing more human tracks? Is there vehicle traffic where you wouldn’t expect it? Has a barely visible trail become heavily worn? Are there signs people are staying in an isolated area for extended periods? Does something simply seem out of place?

None of these observations should turn you into a paranoid wreck every time you go into the woods. Millions of people enjoy America’s wild places without encountering anything remotely like an illegal operation. The point isn’t to be afraid of every footprint you find. The point is to remain aware of your surroundings and recognize when the evidence around you doesn’t fit the location.

Outdoorsmen already use this kind of thinking constantly. A deer hunter notices a fresh scrape and starts considering how recently a buck passed through. A fisherman sees nervous bait along a shoreline and starts looking for predators. A turkey hunter finds tracks crossing a road and knows birds are using the area. A wildlife photographer hears alarm calls and realizes something has disturbed the animals nearby.

We recognize patterns because patterns tell us what’s happening around us. Human patterns deserve the same attention.

Don’t Let Curiosity Make the Decision

I understand the temptation to investigate something strange better than most. My career has been built around asking questions, investigating wildlife mysteries, following unusual reports and going places where interesting things have happened. Dark Outdoors itself exists partly because I’m fascinated by the things that happen beyond the edges of normal civilization.

But there is a difference between investigating a story and blindly walking into a potentially dangerous situation.

If you’re alone in remote country and discover convincing signs that something illegal might be occurring, you aren’t law enforcement and you aren’t obligated to solve the mystery. Back out the way you came if that’s the safest route, avoid confrontation and don’t announce your presence. Don’t handle suspicious materials or enter structures simply to see what’s inside. Once you’re safely away, provide authorities with whatever useful information you can remember about the location and what you observed.

There is no discovery or story worth getting hurt over, and there is certainly no reason to risk a confrontation simply because you want to know what’s at the end of a trail.

The Trail That Doesn’t Belong

I still love finding obscure trails. There is something irresistible about an old path disappearing into timber or a forgotten road cutting through country that looks like it hasn’t changed in decades. Those places are part of what makes exploring the outdoors special.

My experience stumbling into an area associated with a meth lab, however, taught me something I’ll never forget. Not every trail is there for hikers, not every camp belongs to hunters and not everyone who chooses an isolated location wants to be found.

So when you’re deep in remote country and the amount of human activity suddenly doesn’t match the surroundings, pay attention before allowing curiosity to pull you farther down the trail. Sometimes the most important sign in the woods isn’t a bear track, mountain lion print or the impression of a big snake crossing the trail.

It might be a human footprint in a place where you weren’t expecting to find one.

What the Nancy Guthrie Case May Reveal About the Next Generation of Predators (Part One)

The first thing that caught my attention about the Nancy Guthrie case wasn’t that she disappeared.

Sadly, America sees missing person cases every day. Most never become national news. This one did because Guthrie is the mother of NBC “Today” co-anchor Savannah Guthrie. Like millions of Americans, I followed the headlines as investigators searched for answers. But as more information became public, it wasn’t the celebrity connection that kept drawing me back to the story.

It was the setting.

During one of the first media briefings, investigators mentioned the rugged desert surrounding Guthrie’s home. There was even discussion of mountain lions and coyotes. Having spent more than three decades covering wildlife and dangerous situations in the outdoors, that immediately struck me as odd. A mountain lion attack doesn’t simply erase someone. It leaves unmistakable evidence. From everything investigators were saying, it was obvious this was something entirely different.

Then I pulled up aerial maps of the neighborhood.

I found myself studying the winding roads, the homes backed against open desert and the natural terrain surrounding the community. Instead of looking at the case only through the lens of a missing person investigation, I began looking at the landscape itself. What advantages might it offer someone intent on committing a crime? What challenges would it create for investigators trying to reconstruct what happened?

Those questions led me to invite Daniel, host of the Drunk Turkey Show and a former law enforcement officer, to join me on Dark Outdoors. His program has closely followed the Guthrie investigation, and I wanted to hear his perspective on something that had been bothering me since I first saw the maps.

Listen to the Dark Outdoors® interview with Daniel from the Drunk Turkey Show:

Did the location itself help whoever committed this crime?

“I think it could have been an advantage to the person,” Daniel said. “The area definitely was an advantage to the guy.” He pointed to several factors that stood out immediately, including the neighborhood’s somewhat rural character, less-than-ideal cellular coverage and the darkness surrounding the community.

The Catalina Foothills community.

That answer immediately changed the direction of our conversation.

Most public discussions surrounding high-profile criminal investigations focus on suspects, motives or forensic evidence. Daniel instead focused on geography. Before talking about who might have committed the crime, he talked about why this particular place may have appealed to someone willing to commit it.

One aspect of the neighborhood especially caught his attention.

“They don’t have any corner lights,” Daniel said. “It’s super dark.”

He believes those conditions suggest whoever committed the crime may have possessed a familiarity with the area that extended beyond simply driving through it.

“That’s one of the things that makes me feel like the guy’s somewhat familiar with the area, whether that’s he’s from the area or he did a certain amount of surveillance in the area,” Daniel said.

That observation shouldn’t be confused with evidence identifying a suspect. Daniel wasn’t claiming investigators had reached that conclusion. He was explaining how experienced investigators often begin evaluating a crime scene. They study the environment. They look at access routes, visibility, lighting and how someone could move into and out of an area without attracting attention.

Listening to him reminded me of something I’ve noticed while reporting on outdoor-related crime over the last three decades.

Some of the most challenging investigations I’ve covered haven’t unfolded deep in the wilderness or in the middle of crowded cities. They’ve occurred in those places where neighborhoods blend into natural landscapes—desert communities, wooded subdivisions, greenbelts and trail systems where people seek peace, privacy and a connection with the outdoors. Most of those places are incredibly safe. But when someone with evil intentions understands the terrain better than everyone else, the landscape itself can become an advantage.

Daniel pointed to another factor that deserves consideration.

From what he understands, cellular coverage in portions of the area isn’t ideal. That, he said, could make it more difficult to narrow the location of devices or reconstruct movements during critical moments of the investigation. At the same time, he noted the neighborhood is not isolated wilderness. It contains numerous homes and regular vehicle traffic, making the investigative picture even more complicated.

That complexity is one reason the Guthrie case has remained so compelling. Cases like this remind us that modern investigations rarely depend on one piece of evidence. Instead, detectives assemble hundreds or even thousands of small details until they begin forming a clearer picture of what happened.

As our discussion continued, however, Daniel shifted away from geography and began talking about something that immediately caught my attention.

Technology.

Not technology used by investigators.

Technology that may have been understood—or even used—by whoever committed the crime.

That immediately made me think of another case that forever changed how many investigators look at modern offenders.

Bryan Kohberger.

The man accused of murdering four University of Idaho students wasn’t simply another homicide suspect. Prosecutors allege he attempted to minimize the digital trail surrounding the crime, altered his driving route afterward and possessed an academic interest in criminal investigations. Ultimately, investigators used a combination of DNA, surveillance footage and digital evidence to build the case against him.

Whether Kohberger intended it or not, that investigation demonstrated something important.

Today’s offenders aren’t just learning how to commit crimes.

Some appear to be learning how investigators solve them.

I asked Daniel whether he believed we may be witnessing a new generation of offenders—people who understand cameras, digital evidence and modern investigative techniques better than many criminals of the past.

His answer surprised me.

He said what first pushed him in that direction wasn’t one dramatic piece of evidence. It was a collection of small details that, when viewed together, painted a very different picture.

He pointed to a camera system that appeared to record activity before and after a critical period but not during it. He mentioned reports that multiple nearby homes experienced internet issues that night. He noted what he believed was an individual who appeared aware of where cameras were positioned and how they functioned. None of those observations establish what happened or identify a suspect, but together they caused him to begin looking at the case through a different lens.

As Daniel laid out his reasoning, I realized we were no longer discussing only the Nancy Guthrie investigation.

We were talking about whether violent offenders themselves may be evolving.

For decades, crime stories have often portrayed killers as impulsive or reckless. Increasingly, some investigators are confronting offenders who study forensic science, understand digital technology, research investigative procedures and attempt to anticipate how law enforcement will respond. Cases like Kohberger’s suggest that possibility is no longer theoretical.

Then Daniel made another observation that stopped me.

He believes there may be one more piece to the puzzle in the Guthrie case—one that could push this conversation even further into the modern age.

It wasn’t another witness.

It wasn’t DNA.

It wasn’t a cellphone.

It was the possibility that the person responsible may have understood technology in ways most people haven’t even considered.

That discussion led us into cameras, internet disruptions and one possibility that sounds more like something from a crime thriller than a real investigation.

A drone.

Dog Attacks in the Outdoors: The Rise of Feral Dogs

The first thing I noticed was the Rottweiler.

I was scouting a spot along the Sabine River where I hoped to target bowfin, known to many Southeast Texas anglers as grinnel. The area looked promising. There was good access to the water, plenty of cover and all the ingredients that usually get a fisherman excited about coming back with a rod and reel.

Before I ever made it to the shoreline, though, I noticed movement near the edge of the woods.

A large Rottweiler stepped into view. Then I spotted a German shepherd. A pit bull appeared a few seconds later, followed by what looked like a Labrador mix. The dogs were muddy and looked like they had been spending a lot of time outdoors. Whether they had been abandoned, wandered away from nearby homes or simply found their way there, I couldn’t say.

What I did know was that I wasn’t getting out of the truck.

After decades spent hunting, fishing and exploring wild places, I’ve learned to trust my instincts. Sometimes a situation doesn’t feel right, and there is no reason to ignore that feeling just to prove a point.

A week later I returned to the same location.

Two of the dogs were still there.

That bothered me more than the initial encounter because it suggested these weren’t simply pets passing through the area. At least some of them appeared to be living there.

As I drove away, I found myself thinking about a question most outdoorsmen never ask. What if a teenager had come there to fish alone? What if a family had stopped to explore the shoreline? What if someone walking a trail suddenly found themselves face-to-face with animals that no longer viewed people the way a household pet does?

Most people don’t think about dogs when they think about outdoor dangers. They think about alligators, snakes, sharks or wild hogs. Dogs occupy a different place in our minds because they are part of our lives. We hunt with them. Fish with them. Let them sleep in our homes.

Yet the numbers tell a different story.

According to the Texas Department of State Health Services, approximately 4.7 million dog bites occur annually in the United States. Hundreds of thousands of people require medical treatment each year, and children account for a significant percentage of the injuries. The Centers for Disease Control and Prevention has also documented a substantial increase in fatal dog attacks over the last decade.

Put another way, the average American is far more likely to be injured by a dog than by many of the animals that dominate outdoor safety discussions.

That reality became impossible to ignore last year when a man was killed while walking on a public trail near Katy, Texas. Authorities said multiple dogs attacked the victim during what should have been a routine walk. The incident shocked people because it happened in a place where families exercise, jog and spend time outdoors. It wasn’t some remote wilderness area. It was a public trail in a heavily populated part of Texas.

The attack made headlines for a few days before fading from public conversation, but it highlighted an issue that extends well beyond a single tragedy.

Dogs are among the most adaptable animals on earth. Their ability to live alongside people is one reason they have become one of the most successful species in human history. Unfortunately, that same adaptability allows them to survive when people abandon them.

And that is where the story becomes more complicated.

Over the years, I’ve interviewed wildlife biologists, game wardens, ranchers and hunters who all shared a common concern about feral dogs. While the public often focuses on coyotes, bobcats and other native predators, many wildlife professionals consider free-ranging dogs one of the most overlooked threats on the landscape.

Hunters frequently report seeing dogs chasing deer. Ranchers deal with attacks on calves, goats and other livestock. Along parts of the Gulf Coast, free-ranging dogs have been implicated in attacks on nesting birds and sea turtle nests. Trail cameras regularly capture images of dogs moving through remote areas where most people would never expect to find them.

Unlike coyotes, bobcats and other native predators, dogs did not evolve as part of North America’s natural ecosystems. When they become feral, they often behave in ways that disrupt wildlife populations and create conflicts that native predators typically do not.

Researchers studying free-ranging dogs around the world have linked them to impacts on hundreds of wildlife species. In some regions, they are considered one of the most significant invasive predators on the landscape.

The root of the problem is not the dogs themselves.

The root of the problem is human irresponsibility.

Dogs do not choose to be abandoned near parks, boat ramps, hunting leases, wildlife management areas or back roads. People make those decisions. Every year unwanted animals are left to fend for themselves, and while some are rescued or adopted, others learn how to survive on their own.

That survival can come at a cost.

A dog that spends months or years living without human supervision is no longer behaving like the family pet sleeping on a couch. It may become territorial. It may become increasingly wary of people. It may begin relying on scavenging or hunting to survive. When several dogs begin operating together, those changes can become even more pronounced.

That doesn’t mean every stray dog is dangerous.

Far from it.

Many abandoned animals are frightened, hungry and more likely to run away than confront a person. But one of the biggest mistakes outdoorsmen can make is assuming every unfamiliar dog will react like a pet.

Looking for a thriller that gets the details right? In Hammer, author Joe Betar drew on his real-world experience in conservation, anti-poaching, firearms, and tactical training to create a story that feels authentic instead of over-the-top.

I’ve had two separate encounters with aggressive dogs while spending time outdoors. Neither resulted in injury, but both reinforced an important lesson. Situational awareness matters.

The decision to leave that Sabine River location wasn’t based on certainty that the dogs posed a threat. It was based on recognizing that I didn’t have enough information to know whether they did. There were plenty of other places to fish, and no bowfin was worth taking unnecessary risks.

That same mindset applies to outdoor safety in general.

If you encounter a group of unfamiliar dogs in a remote area, pay attention to their behavior. Create distance whenever possible. Avoid approaching them. Don’t attempt to feed them or interact with them. If the animals appear territorial or aggressive, leave the area and notify local authorities or animal control if possible.

Many outdoorsmen choose to carry personal protection while fishing, hunting, hiking or exploring remote locations. Depending on local laws and personal preference, that may include pepper spray, bear spray or a legally carried firearm. Whatever option you choose, understand how to use it safely and responsibly before you ever need it.

Most importantly, trust your instincts.

I never did fish that particular spot along the Sabine River. Maybe those dogs eventually found homes. Maybe they belonged to someone nearby and simply liked roaming the area. Maybe they were completely harmless.

I’d like to think so.

What I know for certain is that the encounter reminded me that not every outdoor threat comes with scales, tusks or a fearsome reputation. Sometimes the most overlooked dangers are the ones we’ve become so familiar with that we stop seeing them for what they can be.

Most dogs will spend their lives being loyal companions, hunting partners and beloved members of the family. Unfortunately, when people abandon them and leave them to survive on their own, the consequences can affect wildlife, livestock and, in some cases, people.

That’s a reality worth remembering the next time you pull into a remote fishing spot and see something that doesn’t quite feel right.

Texas Faces Screwworm. The Key Deer Did 10 Years Ago

Texas is preparing for the threat of New World screwworm. But just 10 years ago, this devastating flesh-eating parasite struck America’s endangered Key deer in the Florida Keys. That little-known wildlife crisis became the last U.S. screwworm outbreak—and the lessons learned there could prove critical as Texas works to keep the parasite from gaining a foothold.

Watch my new video on this topic here

In this exclusive interview, I sit down with Dr. Roel Lopez, Director of the Texas A&M Natural Resources Institute, who worked with the U.S. Fish and Wildlife Service during the 2016 Florida Keys outbreak.

He shares firsthand insight into what happened, how the endangered Key deer were affected, and how one of the greatest wildlife disease eradication efforts in history—using millions of sterile flies—helped stop the outbreak before it spread.

We also discuss:

• Why New World screwworm is so dangerous to livestock and wildlife • The science behind the Sterile Insect Technique (SIT)

• What happened during the Florida Keys outbreak • Why the Key deer story matters to Texas today

• The current screwworm situation along the U.S.-Mexico border

• What ranchers, hunters, veterinarians, and wildlife professionals should know

• Why early detection and rapid response are essential The story of the Key deer is more than a fascinating chapter in wildlife conservation—it’s a blueprint for how science, cooperation, and decisive action can stop one of North America’s most destructive parasites.

As Texas prepares for the possibility of screwworm returning, the past may hold the key to protecting the future.

Crime, Conservation and the Outdoors Collide in Hammer

When most people think about crime thrillers, they picture car chases, shootouts and government conspiracies. Those are certainly part of Joe Betar’s debut novel, Hammer, but what caught my attention was something else entirely.

As someone who has spent decades writing about wildlife, conservation and the outdoors, I immediately recognized the realism behind many of the story’s outdoor elements.

Hammer follows former MMA champion Jack “Hammer” Garrett, who leaves the fighting world hoping to build a peaceful life in the Texas Hill Country centered on family, hunting and the outdoors. That peace doesn’t last long, and he’s drawn into a dangerous international conspiracy.

During my interview with Betar, I asked how his conservation background shaped the story.

“I tried to take everything from my medical background and my conservation background and incorporate pieces of those into the challenges Jack faces,” he said.

Betar’s years working around conservation and anti-poaching efforts gave him firsthand insight into the complex realities of wildlife crime. Rather than presenting poaching as a simple battle between heroes and villains, Hammer explores the criminal organizations behind wildlife trafficking while also showing the difficult circumstances that sometimes drive people into that world.

For readers who enjoy suspense grounded in authentic outdoor experience instead of Hollywood clichés, Hammer offers something refreshingly different. It’s an action thriller, but one with roots in the real world of hunting, conservation and international wildlife crime.

The Texas Killing Fields Are Back in the News Again

Few places in America carry a name as chilling as the Texas Killing Fields.

For decades, the phrase has been associated with a stretch of the Interstate 45 corridor between Houston and Galveston where the bodies of dozens of women and girls were found beginning in the early 1970s. Investigators believe multiple killers may have been responsible for the crimes, and despite years of investigations, documentaries, books and media attention, many of the cases remain unsolved.

Now, more than four decades after some of the most infamous murders occurred, the Texas Killing Fields are making headlines again.

In recent weeks, investigators and volunteers returned to search acreage connected to the case after information surfaced suggesting there could be additional evidence—or possibly even another victim—linked to the long-running investigation. The search was prompted by information allegedly provided by James Dolphs Elmore Jr., a Galveston County man indicted earlier this year in connection with two of the most notorious Killing Fields murders.

To understand why the latest search matters, it’s important to understand why the Texas Killing Fields became one of the most infamous crime scenes in American history.

The term “Texas Killing Fields” generally refers to a collection of murders and disappearances connected to the I-45 corridor between Houston and Galveston. Over the years, more than 30 women and girls have been linked to the area. Some of the most widely known cases involved a 25-acre tract near Calder Road where the bodies of four women were discovered between 1984 and 1991. Investigators have long believed multiple offenders may have operated in the region over several decades.

For years, one of the central figures in the investigation was Clyde Hedrick.

Hedrick had long been linked by investigators to several of the Calder Road murders. Authorities were reportedly preparing to seek indictments against him in connection with the deaths of Laura Miller, Heidi Fye, Audrey Cook and Donna Prudhomme. Before that process could be completed, Hedrick died in March 2026. According to investigators, he died after removing a breathing tube while hospitalized. His death ended any possibility that he would face trial in those cases.

Just days after Hedrick’s death, another major development shocked families who had spent decades waiting for answers.

A Galveston County grand jury indicted 61-year-old James Dolphs Elmore Jr. on charges related to the deaths of Laura Miller and Audrey Cook. Prosecutors allege Elmore played a role in Laura Miller’s death and helped conceal evidence related to both murders.

Court records allege that Elmore supplied a vial of cocaine that was later used in connection with Laura Miller’s death and that he withheld information about the location of the victims’ bodies for decades. Elmore has been charged with manslaughter and felony evidence tampering. The case remains pending.

The indictment represented one of the most significant developments in the Killing Fields investigation in more than 40 years.

It also brought renewed attention to Tim Miller, the father of victim Laura Miller.

After his daughter’s murder, Miller went on to found Texas EquuSearch, one of the nation’s most respected volunteer search-and-recovery organizations. For years, Miller continued his own efforts to find answers in Laura’s case. According to recent reporting, Elmore contacted Miller in 2022 and claimed to have information about the killings. Over the next several years, the two spoke numerous times as investigators continued examining the case.

Those conversations eventually led to the most recent search.

According to Tim Miller, Elmore repeatedly claimed there was another body connected to the Killing Fields. Miller told reporters that Elmore approached him several years ago and insisted there was “another body out here.” Search teams recently returned to the area in an effort to determine whether the claims had any merit. As of the latest reports, authorities have not announced the discovery of additional remains.

The fact that investigators are still searching after more than four decades speaks to the unique nature of the Texas Killing Fields mystery.

Unlike many notorious murder investigations that eventually focus on a single suspect, the Killing Fields have always appeared more complicated. Some murders connected to the broader I-45 corridor have been solved. In 2022, convicted killer William Reece pleaded guilty in several related Texas murder cases and received life sentences. Yet many of the cases historically associated with the Killing Fields remain unresolved. Investigators have repeatedly suggested that multiple offenders operated in the region over the years.

That complexity is one reason the story continues to capture public attention.

The Texas Killing Fields are not simply one cold case. They are a collection of tragedies that unfolded over decades, involving numerous victims, multiple suspects and countless unanswered questions. Every new lead, every search warrant and every arrest raises the possibility that investigators may finally uncover another piece of the puzzle.

For the families who have spent decades waiting for answers, that possibility matters.

And as the recent search demonstrates, authorities are still willing to dig through the past in hopes of finding them.

Flesh-Eating Screwworm Is A Huge Threat-And It’s Back In America

Few parasites in modern history have caused as much concern among wildlife biologists, ranchers, and animal health experts as the New World Screwworm.

To better understand the threat, I recently spoke with legendary wildlife biologist Larry Weishuhn, known to many as “Mr. Whitetail.” Larry witnessed the original screwworm crisis firsthand and observed the damage it caused before the parasite was eliminated from the United States.

Check out the interview with Larry here.

Unlike most parasites, screwworm larvae feed on living tissue. Animals suffering from an infestation can develop severe wounds that grow larger as the larvae continue feeding. Left untreated, infestations can become life-threatening.

The United States once fought a decades-long battle against screwworm, ultimately achieving one of the greatest animal health victories in history by eradicating the parasite from the country. For many Americans, screwworm became little more than a historical footnote.

Today, however, concern is growing once again.

His perspective is particularly valuable because it combines historical experience with decades of wildlife management expertise. During our conversation, we discussed the biology of screwworm, the lessons learned from past eradication efforts, and what wildlife managers, ranchers, hunters, and outdoor enthusiasts should be watching as this situation develops.

One thing is clear: the New World Screwworm is not simply another wildlife issue. It is a parasite with a long history of affecting wildlife, livestock, and rural communities, and its return has captured the attention of experts across multiple fields.

As more information becomes available, continued monitoring, public awareness, and cooperation between wildlife agencies, livestock producers, and animal health officials will be critical.

For those who care about wildlife conservation, hunting, ranching, and the future of America’s natural resources, the New World Screwworm is a story worth following closely.

Wildlife professionals, livestock producers, hunters, and conservationists are closely monitoring developments involving the New World Screwworm and its movement closer to the United States. The potential impacts extend far beyond individual animals.

Whitetail deer, livestock, pets, and even endangered wildlife species could all face risks if screwworm becomes established in areas where it has previously been absent. Beyond animal health concerns, the economic and conservation implications could be substantial.
