A 55-year-old man has been arrested in a 31-year-old cold case involving a young couple murdered in Washington state.
Sheriff’s Officers arrested William Talbott for the November 1987 murders of 20-year-old Jay Cook and 18-year-old Tanya Van Cuylenborg, the Skagit County Sheriff’s Office said.
Investigators tapped a public genealogy website to match crime scene DNA. The analysis was performed by Parabon, a Virginia company.
A digital file containing DNA genotype data from evidence at the crime scene was uploaded to GEDMatch, a public genetic genealogy website, and promising matches were found for two of the suspect’s relatives, the sheriff’s office said.
