First Jury Trial to Use Family Tree DNA Begins in Washington State

Jurors this week heard during opening statements 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 Associated Press reports. William Earl Talbott II was arrested last year and charged with aggravated murder after authorities said they used genetic genealogy to identify him as the person who left his DNA on the clothing of one of the victims. 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.
