In 1992, a man walked into a small grocery store in rural Maryland, and he never left the same way he came in. When a customer found the store owner behind the counter, the floor was covered in blood, but not all of it belonged to him. Somewhere in that struggle, the killer had been cut, too, and he bled onto the tile without knowing it.

 That blood sat in a police freezer for the next 25 years. Scientists could read every letter of the killer’s genetic code. They knew his ancestry. They could have picked his face out of a lineup of one. What they didn’t have was his name. For a quarter of a century, the man who did this walked free, got married, worked a regular job 45 minutes from the scene of the crime, and never told a single soul what he’d done.

 This is the story of how a piece of dried blood, one shopkeeper’s daughter, and a new kind of science finally closed in on him. And how on the morning police finally came for him, it did not end the way anyone expected. It was Sunday, March 20en, 1992. James Essel was 57 years old, and he was doing what he did most weekends, running his store alone.

 Essel owned the Sugarloaf Mountain Market, a small commercial outpost on Old Hunter Road in Komas, Maryland, a quiet stretch of farmland at the base of Sugarloaf Mountain. It was the kind of place where everybody was a regular, where a man could run the register, stock the shelves, and know most of the faces that walked through his door.

 Essel had built a life around that store. He had a daughter, Perpetua, and siblings who knew him as a devoted, hard-working man who simply didn’t take weekends off. Sometime between 5:30 and 600 that evening, a man walked into the market. Investigators would later reconstruct what happened next, piecing it together from the physical wreckage left behind.

Whoever this man was, he hadn’t come to shop. He’d come for the cash register, and he was willing to use force to get to it. What followed was not a quick robbery. It was a fight, a real one. The struggle carried Essel and his attacker behind the checkout counter, and it did not end quickly or quietly.

 When it was finally over, James Essel had been stabbed 29 times. 29 wounds is not the number you get from a man who panics and lashes out once or twice before running. That number tells you something about how hard Esso fought back and how long the two men were locked together before it ended. And in that violence, something happened that the killer almost certainly didn’t notice in the moment, but that would define the next 28 years of his life. He got cut.

Somewhere in that struggle, his own blood hit the floor. He grabbed what cash he could from the register and walked out of that store a killer. He had no idea that he’d left the one piece of evidence that would eventually undo him. At around 6:00, a customer walked into the Sugarloaf Mountain Market expecting to buy groceries.

 Instead, they found James Essel behind the counter in a pool of blood. They ran back outside and called 911. By the next morning, the office of the chief medical examiner had completed the autopsy because of death. Multiple stab wounds, manner of death, homicide. The case was official, and so began one of the strangest journeys in modern American cold case history because the evidence to solve this crime existed from day one.

 The only thing missing was the technology to read it. But here’s what almost nobody realized walking away from that crime scene in 1992. The killer had already been caught. His DNA was sitting right there on the floor. The only problem was nobody on Earth had any way to turn a blood stain into a name. Not yet.

 Crime scene technicians in 1992 did everything right. They swapped the blood trail that didn’t belong to the victim. They photographed the ransacked register. They canvased the area, talked to neighbors, talked to regulars, talked to anyone who’d driven down Old Hundred Road that evening. One lead stood out early.

 A witness reported seeing a black Pontiac Fiero parked in the store’s lot right in that 530 to 600 window. It was specific. It was distinctive, and it went absolutely nowhere because a car model with no license plate and no owner’s name is just a shape in a parking lot among thousands of identical shapes on the road. Investigators also picked up a smaller stranger clue.

Traces suggesting the killer was a Marbor or Marbor light smoker. It painted a faint behavioral sketch of the man they were hunting. Detectives started to form a theory. This wasn’t a total stranger passing through. The killer they suspected had local knowledge of rural Komas. Maybe he’d been in that store before as a customer, blending in with everyone else who ever bought a pack of cigarettes or a gallon of milk from James Essel.

 But theories and cigarette brands don’t make an arrest. What could make an arrest was the blood. Forensic scientists processed that blood sample and extracted a full clean male DNA profile, a genetic fingerprint unmistakably belonging to the killer and no one else. In 1992, this was cuttingedge work. The profile was uploaded into COTUS, the FBI’s combined DNA index system, the national database law enforcement uses to match crime scene evidence against known offenders. And then nothing. Silence.

 No match, no name, no lead. Here’s the part that’s almost hard to accept. It wasn’t a failure of the science. The DNA profile was accurate. It was sitting in the system waiting. The problem was structural. COTUS only works if the person who committed the crime already has a DNA sample on file, usually because they’ve been arrested or convicted of a qualifying felony before.

And the man who killed James Essel had never been arrested for anything. He had no record. He was, as far as any government database was concerned, a ghost, a man who did not exist. Without a database hit, without a name attached to that Pontiac Fiero, and without a confession or a tip that ever materialized, the trail went cold.

Detectives kept the file open. They kept the evidence preserved. But as months turned into years and years turned into a full decade, the murder of James Essel settled into the file cabinet of unsolved Montgomery County homicides, a case where police had the killer’s exact genetic identity and still could not put a name to it.

 For 25 years, that would remain true. The killer’s blood sat in storage, complete and unchanged, waiting for a kind of science that didn’t exist yet. And in 2017, that science finally arrived in the form of two composite sketches that would give this faceless killer for the first time an actual face. In June 2017, the Montgomery County Police Department cold case unit made a decision that would restart the entire investigation.

 They sent the killer’s 25-year-old blood sample to a Virginia based company called Parabon Nanolabs and asked them to do something that would have sounded like science fiction back in 1992. build a face from DNA alone. The process is called snapshot DNA phenotyping and it works by reading single nucleotide polymorphisms, tiny variations in genetic code that correlate with physical traits, eye color, hair color, skin pigmentation, freckling, the underlying structure of a person’s face, ancestry.

 None of it comes from a photograph, a witness description, or a police sketch artist sitting across from a traumatized victim. It comes purely from the molecules in that old blood stain. Parabon’s analysis determined the killer had European or Caucasian ancestry, and it generated a set of specific predicted traits covering his pigmentation and facial geometry.

 From there, technicians built two composite images. Not a photograph of a real face, but a scientifically generated approximation of what this man likely looked like. One image depicted him at a predicted age of 25, roughly matching how old he would have been at the time of the murder. The other projected him forward to age 50, an attempt to show what nearly three decades of aging might have done to that same face.

 On June 12th, 2017, MCPD held a press conference and released both composits to the public alongside the old leads, the black Pontiac Fiero, the Marbor cigarette traces, and a $10,000 reward through Crimeolvers of Montgomery County for any information leading to an arrest. It was a genuine breakthrough. For the first time in 25 years, this case had a face attached to it, even if that face was built from probability and pigment predictions rather than a photograph. It went out to local news.

It circulated. And it still didn’t produce the one thing detectives actually needed, a name. A composite sketch, no matter how scientifically sophisticated, is still just an approximation. It can’t be run through a database. It can’t be cross-referenced against a driver’s license. It relies on someone somewhere looking at that image and recognizing a neighbor, a coworker, a relative, and picking up the phone.

That call never came. So, the file went quiet again. not cold in the same way as before. The department hadn’t given up, and the science kept evolving in the background, but stalled, waiting for the next leap forward. And two years later, that leap arrived in a completely different form.

 Not a face this time, but a family tree. What detectives needed wasn’t a better sketch of a stranger. It was a way to work backward from that DNA to an actual bloodline. And by late 2019, that exact tool had finally matured enough to use. Investigative Genetic Genealogy, IGG for short, is a fundamentally different approach than anything police had access to in 1992 or even in 2017.

 Instead of searching for an exact match in a criminal database, genealogologists take that same highdensity genetic profile and upload it to public consumerstyle genealogy databases, the same kind of platforms ordinary people used to trace their own ancestry and find longlost cousins. The science behind it relies on shared DNA segments called cinemorggans.

Even a killer with no criminal record, no arrests, and no DNA ever collected by police can still share fragments of genetic code with distant relatives, third cousins, fourth cousin, people who’ve never met him and have no idea he exists. As long as one of those relatives has ever taken a consumer DNA test and made their results searchable, from there, it becomes detective work of an entirely different kind.

Genealogologists start reconstructing sprawling family trees branch by branch, generation by generation, using birth records, marriage records, obituaries, and public documents to figure out how these distant DNA matches connect to one another. And more importantly, where those separate branches converge on a single living person who fits the age, sex, and geography of the suspect.

 It’s slow, it’s meticulous, and in this case, it worked. Beginning in late 2019, genealogologists working the Essel case uploaded the killer’s inme profile and began mapping his extended family branch by branch. The tree narrowed by late January 2020, 27 years, 10 months, and roughly 3 weeks after James Essel was killed.

 The investigation had a name, Hans Witz, 51 years old, living in Virginia Beach, Virginia, working as an auto mechanic. no criminal record whatsoever, which explained instantly and completely why Cotus had never once returned a hit on that 1992 blood sample. He had never been arrested for anything, not once in his entire adult life.

 For nearly three decades, Witz had been hiding in plain sight, not as a fugitive, not under a fake name, not on the run. He was simply an anonymous, unremarkable man with a job and eventually a wife living an ordinary life a few hours south of the store where he’d killed someone. Genetic genealogy could point detectives to Hans Witz.

 It could tell them with real confidence that his family tree matched the profile they’d been chasing for 28 years. But a family tree isn’t proof beyond doubt, and it isn’t enough to charge a man with murder. Before detectives could move, they needed something no genealogologist could give them. Witz’s own DNA collected directly from his body, tested against that decades old blood sample.

 They had a name, they had a city, they had a workplace. What they still needed was 48 hours and a warrant. On February 10, 2020, the Montgomery County Police Department, working in coordination with the Virginia Beach Police Department, secured a judicial search and seizure warrant, authorizing them to collect a confirmatory DNA sample directly from Hans Witz.

 The next day, February 11th, 2020, detectives moved. They located wits at his workplace in Virginia Beach and collected a buckle swab, a simple cheek swab, the same kind of test millions of people voluntarily take every year for ancestry curiosity. Witz had no idea what that swab was about to confirm. The sample went straight to the lab for expedited STR analysis, the same fundamental DNA matching technology that had failed to identify him back in 1992.

Only now it had an actual comparison sample to work against. And this time there was no ambiguity, no waiting years for a database hit that might never come. Within the same day, the lab had an answer. Hanswitz’s DNA was an exact match to the blood recovered from the Sugarloaf Mountain Market floor in March of 1992.

 28 years of silence, and it took less than 24 hours to close the gap once detectives finally had the right person standing in front of them. For Sergeant Chris Homerock and the rest of the MCPD cold case unit, this was the moment the case stopped being theoretical. This wasn’t a family tree pointing in a probable direction anymore.

 This was a scientific direct one toone match between Hans’s own cells and blood left behind at a murder scene nearly three decades earlier. It was functionally the fifth time MCPD’s cold case unit had used genetic genealogy to crack open a homicide that traditional forensics couldn’t touch. Detectives moved fast.

 An arrest warrant was drawn up, charging Hanswitz with firstdegree murder, felony murder, and robbery with a dangerous weapon. The plan was to arrest him the following morning. But an arrest warrant only means something once it’s actually served. And what happened the next morning was nothing like the quiet procedural ending this case seemed to be building toward.

 After 28 years, detectives finally had their man dead to rights on paper. What they didn’t yet know was that Hans Witz had no intention of going through a trial and the next morning would end not in an interrogation room but in gunfire. On the morning of Wednesday, February 12th, 2020, detectives from MCPD’s repeat offender section working alongside a US Marshals task force moved in near Hans Witz’s home on Matland Drive in Virginia Beach to execute the arrest warrant.

Witz was in his vehicle when officers approached. In the moments that followed, he produced a handgun inside the car, a threat directed both at the officers around him and by the accounts that followed at himself. Law enforcement facing an armed man refusing to surrender made the decision to open fire.

 Hanswitz was fatally shot at the scene. 28 years after he walked out of a Komaus, Maryland grocery store having stabbed a man 29 times. Hanswitz died in his car a few blocks from the home where he lived quietly undetected for years. There would be no trial, no arraignment, no moment where James Essel’s family could sit in a courtroom and watch the man responsible answer for what he did.

The Virginia Commonwealth Attorney’s Office opened a standard review of the officer involved shooting as is required by law in any case where police use deadly force. But as far as the murder charge itself was concerned, the justice systems usual process, indictment, trial, verdict, sentencing simply never got the chance to happen because the suspect was dead.

 MCPD closed the file through what’s known as administrative cold case resolution. The case is officially solved. The killer officially identified, but there will never be a courtroom to confirm it out loud. It’s a strange, unsettling kind of ending. The forensic evidence was airtight, a direct DNA match confirmed by an independent lab, no room for reasonable doubt.

 But the human resolution, the moment where a killer faces the people he hurt, never arrived. And that left two families on opposite sides of this story, trying to process an ending that offered scientific certainty and almost nothing else. The case was closed. The DNA didn’t lie. But for the people left behind on both sides of this story, closure and answers turned out to be two very different things.

 Within days of the shooting, MCPD released a comprehensive statement, formally naming Hansitz as James Essel’s killer. Walking through the buckle swab match and the details of the fatal standoff for Perpetual Edwards, James Essel’s daughter, the news landed like a wave she’d stopped expecting to come. I was in a dream.

 I couldn’t believe what I was hearing at the time, she told reporters. She described the shock of learning all at once that the man responsible had been identified and that he had spent nearly three decades simply living his life unbothered while her family carried the weight of an unsolved murder. I wish the guy could have served time for the crime, she said.

 But it’s just a relief to know that it’s over is a huge relief for me and my siblings. It’s a complicated kind of relief. the certainty of knowing without the satisfaction of watching justice actually play out in a courtroom. On the other side of this story, Haiti Witz, who had been married to Hans for 6 years and had known him since childhood, released her own statement.

 She offered condolences to the Essel family, calling their loss a horrible pain to bear. But she also pushed back hard against how her husband was being portrayed, insisting he was not a fugitive, had never been arrested, and had lived his entire adult life with a clean record. Early reports had briefly described Witz as a longtime fugitive language that police later corrected.

 Hitz hadn’t been hiding under an alias or running from anyone. He had simply never been caught living under his real name the entire time, invisible to law enforcement purely because no one had ever had a reason to test his DNA. And even with the case officially closed, certain questions were never going to get an answer because the only person who could answer them died in that car on Maitland Drive.

 Sergeant Homrock himself acknowledged this directly. Without an interrogation, without a confession, investigators will never truly know why Hitz targeted that specific store or what pushed a robbery into 29 stab wounds. There’s no official record of what brought him to rural Komas, Maryland in the first place, or what his life looked like there in 1992.

 The stolen cash was never recovered. The full story of that day, the why behind the violence died with him. What remains is the forensic record, a blood sample from 1992, a face built from that blood in 2017, a family tree traced back to one man in 2020, and a DNA match confirmed within 24 hours of finally testing the right person.

 Science answered the question of who. It could never answer the question of why. Woven directly into the script above through recurring openloop structure, each section closes on an unresolved question. Who is this man? Why did the database fail? What will the science of 2017 finally reveal? Will a family tree be enough? What happens when detectives finally knock? And what does justice look like when the killer never faces trial? With each following section immediately answering it before opening the next thread? The murder of James

Essel is in some ways the story of two timelines moving at completely different speeds. The crime itself took minutes. The resolution took 28 years, 4 months, and change. bridged not by a lucky break or a deathbed confession, but by a slow, steady evolution in forensic science. From a DNA profile that meant nothing without a matching record to a phenotype sketch that gave a faceless man a face to a genealogical map that finally gave that face a name.

 It’s also a sobering reminder of how fragile the old system really was. Hanswitz wasn’t clever. He wasn’t running a criminal enterprise or evading capture with elaborate planning. He simply never got arrested for anything else in his life, which meant the one database built to catch him had nothing to compare his blood against.

 It took an entirely different branch of science, one borrowed from ordinary people curious about their own ancestry to finally close that gap. And in the end, the case closed the way so few true crime stories do. Not with a trial, not with a verdict, but with a DNA match, a knock on a car window, and a decision made in seconds that ensured the world would never hear Hans Witz explain in his own words what happened inside that store in 1992.

 If you want to understand exactly how investigators can build a stranger’s family tree from nothing but a blood stain, how genetic genealogy actually works, case by case, match by match. I’ve broken down the full mechanics of it in another video using one of the cases that helped pioneer the technique. Go watch that next because once you understand how this science actually works, you’ll start noticing it behind almost every cold case that’s been cracked open in the last 5 years.
