West Memphis Three

Investigators theorized the bodies of Stevie Branch, Christopher Byers, and Michael Moore had been mutilated in a Satanic ritual, but could they have been torn apart by animals?

After almost 20 years behind bars, Damien Echols, Jason Baldwin and Jessie Misskelley, Jr. were released from prison as part of a plea deal.

Terry Hobbs, the stepfather of West Memphis Three murder victim Stevie Branch, has denied any involvement in slayings of Branch and his two friends.

Law enforcement believed the 1993 murder of three 8-year-old boys was the work of a Satanic cult led by local teen Damien Echols.

Celebrities like Johnny Depp, Peter Jackson, Eddie Vedder and Natalie Maines used their status and income to help free the West Memphis Three in 2011.

"There was something about Damien that resonated with me," said Lorri Davis of watching the "Paradise Lost" documentary, which led her to meet future husband Damien Echols.

Damien Echols was sentenced to death in 1994 for the infamous West Memphis murders of three young boys, but was freed in 2011.

The three Arkansas teens interrogated in "True Detective" bear a resemblance to Damien Echols, Jason Baldwin, and Jessie Misskelley — the trio was arrested in the early '90s in connection with a triple-murder in a small Arkansas town.
