In February 1987, a Michigan couple ended their Thursday evening as they always did. Terry and Roxanne Wood had dinner at a local restaurant, then drove separately to their usual bowling alley, where Terry played in a weekly league and Roxanne often joined him and friends afterward. Around 12:30 a. m.

, Roxanne said goodbye and drove home alone. Terry stayed to finish the evening with the group before heading home about 45 minutes later. When he turned onto their street, the house was dark. No lights.

No sign anyone was awake inside. He entered and found Roxanne inside. He rushed to check if she was still breathing. There was no sign of life.

He grabbed the phone and called for help. Police arrived within minutes. Officers searched the home for a point of entry. They found no broken locks, no shattered glass.

Investigators later determined the back door was simply unlocked. That left them standing in that kitchen facing a question that would define the case for decades: if no one had forced their way in, had Roxanne allowed someone inside herself? Roxanne Wood was 30 years old. She grew up in Niles, Michigan, graduated from Niles High School in 1974, and soon after married Terry.

The couple settled in the same town where she had been raised. She worked in customer service at a plastics manufacturing company just across the state line in South Bend, Indiana. Colleagues and neighbors described her as someone easy to get along with, the type who left a quick impression on others. Her sister Janette was especially close to her, their relationship more like a lifelong friendship than mere siblinghood.

The two had plans to go shopping together the following Saturday, an offhand plan people make assuming there will always be another weekend. That one never came. From the start, investigators fixed their attention on the person closest to her: her husband. At the crime scene, officers described Terry’s behavior as agitated to the point of being difficult to control.

Reports noted that first responders placed him in the back of a patrol car that night in an attempt to calm him while investigators worked around him. Days later, when called in for formal questioning, Terry asked to speak with a lawyer at the beginning of the interview, a right the law guarantees him but which investigators at the time treated as a sign of guilt. From that moment, the investigation almost entirely revolved around him. Janette later recalled that a detective told Terry directly they believed he was responsible and would not rest until he was behind bars.

Yet prosecutors ultimately found insufficient evidence to charge him. Within months, the case went cold, with Terry officially remaining the only person around whom suspicion circled. In April, Terry offered a $15,000 reward from his own money for help identifying Roxanne’s killer, a sum offered by a man his community still silently suspected. There was, however, physical evidence sitting in police storage the entire time.

In 1987, DNA technology could only confirm that the sample existed, not identify whose it was. As the technology slowly advanced through the 1990s, the sample was finally entered into CODIS, the national criminal DNA database, in 1999. It produced no match to any known criminal. During the same period, investigators were also able, for the first time, to compare the sample directly to a reference sample from Terry himself.

There was no match. That distinction mattered. Comparing a sample to one known person required far less genetic material than building a full profile capable of searching among millions of strangers. The evidence had always been enough to exclude or include a person, one at a time.

It was never enough, with the technology of the 1990s or even the early 2000s, to identify a completely unknown person. Terry Wood was formally excluded. But that exclusion never reached the public the way the original suspicion had. Residents of Niles, who knew the case only through rumor, continued to look at him with suspicion for years, even after investigators themselves had moved past it internally.

For the case itself, the exclusion solved nothing. Police were left with a single trace of unknown male genetic material and nothing else. Evidence that someone else had been in that kitchen, with no way yet to identify him. In 2001, investigators reopened the case and re-interviewed more than 200 people.

No new lead emerged. The sample itself remained unchanged, still unable to do more than confirm the identity of the person who had not committed the crime. Building a profile capable of identifying a stranger required a form of testing that did not exist in 2001. The case returned to the archives a second time.

By 2020, more than 10,000 hours of investigation had been invested in the file across multiple generations of detectives, without yielding a name linked to the evidence. Detective John Moore, who worked the case in its final years, put the cost simply: an entire generation of young women in Niles had grown up not knowing whether the person responsible was still free, walking among them. The case had not stopped because anyone stopped caring. It stopped because the specific method needed to read that sample for an unknown suspect had not yet been invented.

What changed the case had nothing to do with a police laboratory. It began with a group of people who had never worked a real criminal case in their lives. In 2020, Western Michigan University launched a formal cold case partnership with the Michigan State Police, founded and led by criminal justice professor Ashlyn Koesten. Her approach was simple: connect students to real unsolved cases that had stalled not because evidence was lost, but because no one had enough time to work them properly.

The Roxanne Wood file became the first case in the program. More than 3,000 pages of reports, interviews, and evidence records dating back to 1987 had been archived over decades by different investigators, none organized in a way that made cross-referencing easy. Student McKenzie Staham and her colleagues spent roughly 1,200 hours over eight months digitizing and indexing all of it, building a searchable index from what had previously existed only as scattered paper. What once took investigators days to cross-reference could now be searched in minutes.

It was unglamorous work, no interrogations, no dramatic discoveries in the moment, but it gave investigators a more usable foundation for what came next. By this point, the standard path forward had already failed twice. What investigators needed was a method designed for evidence too limited for traditional testing: investigative genetic genealogy, a technique only a few years old at that time. Before Michigan State Police found a laboratory willing to take the case, two other genealogy companies reviewed the sample and rejected it, concluding it was too degraded to work with.

The case eventually went to Identifinders International, a California laboratory specializing in evidence other labs had deemed unworkable, while parallel forensic examination continued at the Michigan State Police forensic laboratory in Grand Rapids. Identifinders founder Dr. Colleen Fitzpatrick described exactly what her team received: only about 3 percent of the genetic material her lab would normally consider usable. To extract anything useful, her team relied on whole genome sequencing, a method capable of reading far more of a damaged sample than the tests used in 1987 or 2001.

It took time and repeated attempts, but the lab eventually built a complete, searchable profile from what remained, at that time the smallest amount of DNA the lab had ever successfully worked with. For the first time since Roxanne’s death, that DNA existed in a form someone could actually search among strangers, not just compare to a name already in records. In April 2021, that profile reached Gabriella Vargas, an investigative genetic genealogist working independently from Northern California. She had no prior connection to the case, no ties to Michigan, and had been eight years old when Roxanne died.

Other genealogists had already reviewed the sample and declined to work on it. Vargas did not share their hesitation. She later said she believed the case was solvable, and that she believed she could solve it. She uploaded the profile to two public genealogy databases, GEDmatch and Family Tree DNA, platforms where people voluntarily upload their DNA results, some choosing to allow law enforcement to search their matches for ongoing investigations.

Without that voluntary participation, nothing that followed would have been possible. The closest matches that appeared were distant relatives at the third and fourth cousin level. Vargas began building two branches of a family tree simultaneously, one tracing back to an ancestor born in 1797, the other to 1823, cross-referencing birth records, marriage records, and geographic locations as she worked. Eventually, the two branches converged at what genealogists call a union couple, the point where two family lines meet.

This couple, born around 1920, would have had children in the 1940s or 1950s. That meant the unknown DNA belonged to one of their three sons. Background checks cleared two of the three brothers. Only one remained.

His name was Patrick Wayne Gilham. Four days passed from the moment Vargas opened the file to the moment she had his name. A single preserved sample, one laboratory willing to try where two others had refused, four days of genealogical work, and a name no one had ever considered suddenly existed. But a name extracted from a family tree is not evidence in a courtroom.

Before any arrest became possible, investigators needed something no genealogist could provide: Gilham’s own DNA, obtained without revealing he was a suspect in a murder more than three decades old. Patrick Gilham had lived only four miles from the Wood family home in 1987. When investigators examined his record, they found he already had a substantial criminal history. In 1980, seven years before Roxanne’s murder, Gilham broke into a woman’s home in Gary, Indiana, and attacked her there.

The victim survived, identified him, and testified against him in court. He was convicted and sentenced to a maximum of 14 years, serving about half before being released on parole on August 5, 1986. Six months later, Roxanne Wood was killed. Despite this proximity, despite his violent criminal record, Gilham’s name never appeared in the original 1987 investigation.

Investigators at the time had no reason to suspect him. There was nothing on paper linking him to Roxanne at all. Surveillance began quietly. Investigators learned Gilham smoked.

In June 2021, an undercover officer tracked him to a laundromat and recovered a cigarette he discarded in a public area. Property that is discarded holds no expectation of privacy. Once he threw it away, it was no longer under his control. The sample was tested at both laboratories working on the case.

Results came back from both without ambiguity. Gilham’s DNA matched the profile preserved from the 1987 crime scene. In July 2021, Gilham was brought in for an interview, told only that police wanted to inquire about an old case. When shown a photograph of Roxanne, he said he had never met her and claimed he had only visited Michigan once, for work.

Investigators already knew this was untrue. A second interview followed as the case crystallized. Confronted directly with the DNA match, Gilham’s answers changed. He said he had no idea how his DNA could be there, that he did not remember.

He requested a lawyer before the interview ended. Investigators spent the following months systematically building the case before taking any step. On February 17, 2022, nearly 35 years to the day after Roxanne’s murder, Gilham was arrested at his home in South Bend and charged with open murder and breaking and entering an occupied dwelling. What remained now was not determining who had done it.

That question had already been answered. What remained was what would happen once the case reached a courtroom. On March 18, 2022, Gilham entered a plea of no contest to second-degree murder, a plea carrying the same legal weight as a guilty plea without a formal admission. At the sentencing hearing on April 25, Roxanne’s family addressed the court directly.

Her sister Janette did not soften her words. She said his actions had sentenced the entire family to life imprisonment, while he had spent most of those 35 years as a free man, and credited the capable investigators and modern technology that finally solved the case. Her brother Brad was equally direct, telling the court that if any opportunity for early release ever arose, everyone would hear his voice opposing it. Gilham also addressed the court, saying he was very sorry for what he had done and hoped the family could one day find it in themselves to forgive him.

He was sentenced to a minimum of 23 years and a maximum of 50. He was 67 years old then, meaning he would not be eligible for release until he was 90. There was another person in that courtroom. Robert Frag, husband of the woman Gilham had attacked in 1980, attended to support the Wood family.

At one point, he found himself face to face with Terry, the man finally formally cleared after decades of suspicion. Frag later described shaking his hand, noting Terry was trembling noticeably with tears in his eyes, and said he felt more sympathy for him in that moment than for anyone else he had ever met. Gilham is currently serving his sentence at the Carson City Correctional Facility in Michigan. The case later drew national attention through a CBS 48 Hours episode titled The Unsolved Murder of Roxanne Wood.

Terry Wood declined the network’s request for an interview. After 35 years of public suspicion, there was little reason left to trust the spotlight. The evidence had existed in 1987. It had been sufficient, in the end, to clear Terry Wood.

What it could not do, for 33 more years, was tell investigators whose DNA the sample actually belonged to. The sample never changed. What changed was the science developed to read it, and the people willing to spend eight months organizing a paper file, or four days tracing a family tree back over two centuries, to finally give it a name. That name had never appeared anywhere in the Roxanne Wood case file.

Now, it is the only name connected to her.
