At 35, Damien Echols has spent his entire adult life on death row in an Arkansas prison alongside Jason Baldwin and Jessie Misskelley, who are both serving life sentences. The trio, all convicted of a triple murder, are known as the West Memphis 3, and they have gained widespread support from musicians including Dixie Chick Natalie Maines and Pearl Jam's Eddie Vedder, and actor Johnny Depp, who are determined to prove the men's innocence. "They were easy targets... Every single piece of evidence points to their innocence, not to their guilt," says Depp in an interview with 48 HOURS MYSTERY correspondent Erin Moriarty. "People need to stand up and say, yeah, it's time to find the real killers. Let's find justice." Erin Moriarty reports on 48 HOURS MYSTERY.
