In 1993, the mutilated bodies of three 8-year-old boys were found in West Memphis, Arkansas. Three teenagers - Damien Echols, Jessie Misskelley, and Jason Baldwin - were convicted of the murders based primarily on circumstantial evidence and Misskelley's coerced confession. In 2011, after 17 years in prison, new DNA evidence excluded the three men and implicated new suspects. This case highlights the importance of proper chain of custody and evidence preservation procedures to avoid wrongful convictions and allow for the possibility of exoneration through advances in forensic technology.
