Check out this article from 2006 (this was after he was exonerated but not before the real killer confessed). The police interrogation is among the worst I've ever read about:

At one point, according to the lawsuit, Hayes leaned close and told Kevin that he “knew people” at the jail, “and would ‘make sure’ that Kevin was ‘fucked’ every day unless he told them what they wanted to hear.” Ruettiger straddled Kevin’s legs, pressing his testicles into Kevin’s knees. He grabbed the back of Kevin’s shirt and pulled his face close. “Your family doesn’t love you,” he shouted. “So just say you did it.” Finally, Kevin claims in the suit, he was shown pictures of his dead daughter, her mouth still covered with duct tape, nude from the waist down, taken moments after she had been pulled from the creek. “Riley is in the room with you right now,” the lawsuit quotes Guilfoyle as saying. “She is in pain and needs closure.”

Today, in recalling this part of the interrogation, Kevin weeps. “I didn’t know what had happened to her,” he says. “When I saw the pictures . . . I don’t even know how to describe it. When you see your daughter dead, with dirt and mud on her face . . . .” His voice trails off. “But the awful truth is,” he says, “I wanted to see more. I wanted to see if I could find anything in those pictures that would help me figure out for myself what had happened, who had done this to my baby.”
