West Memphis Three to appear at "Paradise Lost 3: Purgatory" screening

(CBS/AP) The West Memphis Three are scheduled to appear at a screening of the HBO film "Paradise Lost 3: Purgatory" at the New York Film Festival at the Lincoln Center in New York.

Damien Echols, Jason Baldwin and Jessie Misskelley were initially convicted of killing three 8-year-old Arkansas Cub Scouts in 1993, but always said they didn't commit the crime. In August 2011 after spending almost two decades in custody, they plead guilty to lesser charges while maintaining their innocence, and were set free.

Despite the fact that Misskelley was initially barred from associating with felons except for his immediate family, and Echols and Baldwin were prohibited from associating with felons except for each other, the three are now allowed to appear together for certain events.

The West Memphis Three were allowed to change their original plea because new DNA evidence has surfaced. Many celebrities, including Johnny Depp and Eddie Vedder, have supported the defendants throughout the years. "I hadn't seen daylight in almost a decade. I hadn't been exposed to sunlight...for almost 10 years," Echols told Piers Morgan on CNN. He had been on Death Row for 18 years.

The saga of the men has been chronicled through the "Paradise Lost" series, anda feature film is reportedly in pre-production.
