EVERETT, Wash. - Jurors in Washington state on Friday heard about the mysterious final days of a young Canadian couple killed in 1987 — as well as the novel method authorities used to finally make an arrest three decades later. The practice involves identifying suspects by entering crime-scene DNA profiles into public databases that people have used for years to fill out their family trees. She built a family tree and determined the source must be a male child of William and Patricia Talbott, of Monroe. William Talbott II, now 56, was their only son. Since then, authorities have used the DNA method to identify more than 60 cold-case suspects across the country.
