Law enforcement has been able to tap into this trove of information to help solve cold cases that are decades old. Experts share how the process works and whether there are ethical concerns about sharing one's genetic data online. With guests: Claire Glynn, associate professor of Forensic Science at the Henry C. Lee College of Criminal Justice and Forensic Sciences at the University of New Haven; Patricia Kosseim, Information and Privacy Commissioner of Ontario; Toronto Star crime reporter Jennifer Pagliaro; and Ellen White, investigator at Pulse Private Investigations and host of the podcast, "Whereabouts Unknown."
