Trial begins in case of young Canadian couple killed in 1987

EVERETT, Wash. (AP) — Jurors in Washington state are hearing about the mysterious final days of a young Canadian couple found slain in 1987 — as well as the novel method authorities used to make an arrest three decades later.

William Earl Talbott II wasn't arrested until last year, when authorities said they used genetic genealogy to identify him as the person who left his DNA on one of the victims.

Opening statements began Friday with a prosecutor describing how 18-year-old Tanya Van Cuylenborg and her boyfriend, 20-year-old Jay Cook, left Victoria, British Columbia, for an overnight trip to Seattle.

When they didn't return, their families began a frantic search for them, including renting a plane to try to spot their copper-colored van. Their bodies were found in separate locations about a week later.
