Caine was wrongfully convicted in the 1986 stabbing deaths of a South Side couple and spent almost 25 years in prison for the crime. He said he was tortured by police under Chicago Police Commander Jon Burge into making a false confession. He was released from prison a year ago.
"Because today I've been truly vindicated. I've been declaring my innocence since April 1986. At that time, few people believed in me," Caine said.
The murders will be expunged from Caine's records and he will now be eligible for monetary compensation from the state.
