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 and Hobbs' son Stevie. In August 2011 the three men were released from prison after entering a plea that allowed them to maintain their innocence, while acknowleding that prosecutors had enough evidence to convict them.
