An attorney involved in the West Memphis Three case, in which three teenagers were convicted of killing three boys in 1993, is claiming that evidence related to the case that was believed to be lost or destroyed has been located at the West Memphis Police Department, local CBS affiliate WREG reported.

Attorney Patrick Benca, who represents defendant Damien Echols, wrote in a Wednesday statement that he located evidence from the case after being granted access to the police department through an Arkansas state court order, according to WREG. He said the evidence, which he claims city officials previously told him was lost, destroyed or missing, was found intact and organized.

Benca said he hopes the evidence can be tested for DNA to help clear the name of his client, who along with Jason Baldwin and Jesse Misskelley Jr. was convicted of murder as a teenager in 1994. Prosecutors in the case argued that Echols, Baldwin and Misskelley had killed three boys the prior year as part of Satanic rituals. The three men spent nearly 17 years in prison before being released in 2012 after entering an Alford plea, pleading guilty while maintaining their innocence.
