Damien Echols and two other men spent 18 years in prison after being wrongfully convicted for the 1993 murders of three 8-year old boys in West Memphis. What do Damien Echols and Johnny Depp have in common? A good deal of personal history and matching tattoos, actually.

Damien Echols, Jessie Misskelley, and Jason Baldwin were the subjects of the "Paradise Lost" documentaries. Depp saw the documentaries and decided to get involved. Depp, along with other celebrities such as filmmaker Peter Jackson and musicians Eddie Vedder, Natalie Maines, and Henry Rollins made financial contributions to help free the three men. Depp and Echols have become close friends who frequently hit the tattoo shops together. Echols even designed one of Depp's tattoos. Echols, Misskelley, and Baldwin have come to the forefront again due to the upcoming release of "West of Memphis," a documentary about the unjust conviction of the men who would come to be known as the West Memphis Three.
