#217 - When 36-year-old computer programmer Lisa Valdez was found dead inside her upscale San Francisco apartment, the police immediately suspected she was killed by someone she knew. But even after the police collected DNA samples from all of her male friends and family members, they were no closer to making an arrest, and the case eventually turned cold. Can new DNA testing be used to help track down a killer? Support My Work If you love the show, the easiest way to show your support is by leaving us a positive rating with a review.
