If you're familiar with the case of the West Memphis Three, you'll be aware that attempting to condense the complexity, length, and injustice of it all into a few paragraphs is near impossible. If you're unfamiliar with it, then watching the excellentParadise Lost trilogy of documentaries—as well as Amy Berg's equally fantastic West of Memphis—serves as a good introduction to this astonishing story.
In short, the West Memphis Three are Damien Echols, Jason Baldwin, and Jessie Misskelley, Jr. They were three boys from West Memphis, Arkansas, aged between 16 and 18, who in 1993 were arrested and convicted for the murder and sexual mutilation of three eight-year-old boys—Steve Branch, Michael Moore, and Christopher Byers. Due to the apparent acts of mutilation it was accused that what had taken place was in fact a satanic ritual—human sacrifices. The pressure on the police to solve the heinous crime was huge, which, combined with the town having a history of supposed witchcraft and satanic practices, left a community shattered and in terrifying fear. Echols, Misskelley, and Baldwin were picked up as they were known friends and were into what a lot of alienated teenagers were into: heavy metal, wearing black, being left alone, and doing their own thing.
