kulakowski's t-shirt had come from barry bench. >> the paternity testing showed that the john doe dna on the shirt came from the father of this young woman, katherine exstat, who was barry bench's daughter. >> unbelievably, when this evidence was presented to the court, the judge refused to grant a new trial. he said he had no proof that barry bench was katherine's biological father. >> you would think you would be home the next day. you wouldn't think people would drag this out. >> this is the kind of people i'm dealing with. >> with more prompting, the state of new york exhumed barry bench's body and took a dna sample. it conclusively matched the saliva on sabina kulakowski's t-shirt and roy brown was finally released from prison, 15 years to the day he was convicted.
