The 1987 Murder of Roxanne Wood: How Identifinders DNA Caught Patrick Gilham After 35 Years

On the night of February 20, 1987, 30-year-old Roxanne Wood returned to her Niles Township, Michigan home after an evening out with her husband. When her husband arrived minutes later, he discovered a scene of unimaginable violence: Roxanne had been brutally assaulted and murdered on the kitchen floor. The weapon had vanished, and for thirty-four years, the crime haunted southwest Michigan. In 2021, pioneering genetic genealogists at Identifinders International extracted viable DNA from an infinitesimal 0.82-nanogram sample, cracking the Roxanne Wood murder and convicting 67-year-old Patrick Gilham.

The Night of the Murder in Niles: February 1987

Roxanne Wood and her husband Terry were enjoying a Friday evening at a local bowling alley in downtown Niles, Michigan. Roxanne drove home ahead of her husband around 11:30 PM. When Terry arrived at their suburban home roughly forty-five minutes later, he found the front door unlocked and his wife lying deceased on the floor, her throat cut with a kitchen knife that the assailant took from the scene.

Michigan State Police investigators combed the property, recovering biological trace evidence left on Roxanne’s body. Despite rigorous questioning of Terry Wood and dozens of acquaintances, Terry was cleared of suspicion, and the perpetrator remained completely unidentified as decades passed.

The 0.82 Nanogram DNA Miracle

In August 2020, Michigan State Police Detective Chuck Christensen partnered with Dr. Colleen Fitzpatrick and Misty Gillis of Identifinders International. The forensic obstacle was immense: only 0.82 nanograms of degraded DNA remained in evidence freezers—far below conventional testing thresholds.

Using specialized whole-genome sequencing protocols developed by bioinformatician Dr. Greg Magoon, Identifinders generated an actionable SNP dataset. Genealogists constructed ancestral family trees tracing paternal lineages back to the early 1800s, narrowing down millions of possibilities to a single family branch in northern Indiana.

Cigarette Butt Surveillance and Confession

By mid-2021, genealogists identified 67-year-old Patrick Wayne Gilham of South Bend, Indiana, who had a 1980s criminal record for armed robbery and sexual assault in the area. Undercover Michigan State Police detectives shadowed Gilham and retrieved discarded cigarette butts from a public parking lot.

Forensic testing confirmed a 100% statistical match between the cigarette DNA and the crime scene sample. On February 14, 2022, detectives arrested Gilham. During questioning, Gilham broke down and admitted to the homicide.

Sentencing and Historic Closure

In April 2022, Patrick Gilham pleaded no contest to second-degree murder in Berrien County Trial Court. Judge Sterling Schrock sentenced Gilham to 23 to 50 years in state prison, ensuring the killer will remain incarcerated for the remainder of his life. The case proved that even nanogram-level degraded cold case DNA can deliver absolute justice.

Forensic Serology & The Niles Kitchen Crime Scene

In the early morning hours of February 20, 1987, thirty-year-old Roxanne Wood was murdered inside her home on Tam-O-Shanter Drive in Niles, Michigan, after returning from a bowling alley with her husband. When her husband arrived home forty-five minutes later, he found her fatally injured on the kitchen floor, having suffered severe blunt trauma and a slashed throat. Michigan State Police detectives recovered the murder weapon—a bloodstained frying pan—and preserved biological swabs from the victim’s body.

In 1999, Michigan State Police extracted a male STR DNA profile from the preserved evidence, but queries in state and national CODIS databases yielded no matches. For over three decades, the investigation remained unsolved, with suspicion often falling unfairly on surviving family members.

Identifinders International & Cigarette Butt Surveillance

In 2020, Michigan State Police Detective Chuck Christensen partnered with forensic genetic genealogist Colleen Fitzpatrick of Identifinders International. Using dense SNP microarray data, Fitzpatrick and her team constructed complex family trees spanning thousands of relatives, isolating Patrick Wayne Gilham of South Bend, Indiana, as the prime suspect.

Undercover detectives placed Gilham under surveillance, retrieving a discarded cigarette butt from a public sidewalk. DNA extracted from the cigarette butt matched the 1987 crime scene evidence with statistical certainty. In February 2022, Gilham was arrested, pleaded guilty to second-degree murder, and was sentenced to a minimum of 23 years in state prison, solving the 35-year-old homicide.
