This episode covers the murder of Roxanne Wood in 1987, the investigation led by Michigan State Police, and the eventual identification of her killer, Patrick Gillum. Key participants include genetic genealogist Gabriella Vargas, Dr. Ashlyn Kirsten, and members of Roxanne's family.
Roxanne Wood was found murdered in her home, prompting an investigation that initially focused on her husband, Terry Wood. Despite his aggressive behavior during the police call, investigators lacked sufficient evidence to charge him, and the case went cold.
In 2020, Dr. Ashlyn Kirsten and her students at Western Michigan University began digitizing the extensive case files. This effort aimed to breathe new life into the cold case, leading to the involvement of genetic genealogist Gabriella Vargas.
Vargas successfully generated a genetic profile from a tiny DNA sample and utilized online genealogy databases to trace the lineage of the suspect. This process led to the identification of Patrick Gillum, a man with a violent history.
After collecting a confirmatory DNA sample from Gillum, investigators arrested him in 2022. He later pleaded no contest to second-degree murder, providing closure for Roxanne's family after decades of waiting.
Roxanne Wood's 1987 murder was solved in 2022 when DNA linked Patrick Gillum to the crime, exonerating her husband Terry Wood.
