Christopher Williams is suing the city of Philadelphia after spending over three decades in prison and 25 years on death row for murders that he was exonerated for, according to WHYY.

In February, he was released from prison after the Philadelphia District Attorney’s Conviction Integrity Unit investigated his cases and found prosecutorial misconduct, such as secret exculpatory evidence. 

Now, Williams’ mission is to seek accountability for the wrongs that were done on him.

“To this day, I don’t know at times what freedom feels like, but I’m trying to figure it out. I don’t have time. I don’t have time to pity myself because I feel as though I stand on the backs of individuals who paved the way for me, my parents, my grandparents, their parents, individuals in whom survived the bowels of the slave ship, and survived on this shore,” he said at a press conference. “I stand on their backs and that’s why I’ve never given up on myself and I can never give up on individuals and whom I left behind in those cages.” 

The civil lawsuit was filed on Dec. 1 and names culprits like the city of Philadelphia, the Philadelphia District Attorney’s Office, the Philadelphia Police Department and 17 police detectives or their estates, according to WHYY.

Civil rights attorney Ben Crump is Williams’ lawyer as he is seeking $100 million in damages. 

“It is Philadelphia who has one of the worst records on wrongful convictions, especially of Black men,” Crump said. “It is our hope here today that we will start the process of giving the city of Philadelphia an opportunity to go from worst to first.”
