Unsolved Season 3 Episode 2 Unsolved: Who Was Waiting in the Weeds?

On May 13, 1994, Trellis Sykes left her grandmother's house in Houston's Sunnyside neighborhood to walk to school. But the 16-year-old never made it there. Instead, while taking a shortcut through a field of tall weeds, she was hunted down, sexually assaulted and murdered. Someone's DNA was found on her - but whose? Police say it's time to try testing that DNA again. Almost three decades later, they're sharing new details and crime scene photos from the case. Plus, the prison interview with a serial rapist convicted in other attacks in Sunnyside.
