Damien Echols, left, a producer of the film "West of Memphis," mingles with Mark Byers at the premiere of the documentary film at the 2012 Sundance Film Festival in Park City, Utah, Friday, Jan. 20, 2012. Echols spent 18 years on death row in Arkansas after being accused, along with Jason Baldwin and Jessie Misskelley Jr., of the murders of three eight-year-old boys including Byers' son Christopher. In August 2011 the three men were released from prison after entering pleas that allowed them to maintain their innocence, while acknowledging that prosecutors had enough evidence to convict them.
