Calhoun tells abc13 he was searching the internet, stumbled upon Flores' story and found out police were looking for him. He turned himself in but repeatedly told detectives he is innocent.
"I think it's a horrible crime, man. I hate that I was ever mixed up with it, man. I haven't had no sleep. I'm tearing up here and there and I'm still scared for my life. At the same time, I just hope that the family really finds justice," Calhoun said. "I've been out here trying to change my image and doing so, this put a big damper in it, but at the same time, I don't think God would've allowed it."
Calhoun says he's ready to help that north side community and help Flores' family in the search for the real killer.
Several people have been calling for a crackdown on homeless men in the area near the murder scene. In response, the Salvation Army changed the rules at Harbor Light Center.
Also on Saturday, a group of people held a special walk to honor Flores. The Fearless Walk Movement held what it calls "a march for a change and unity." Their goal is to create a safer passage for children and future generations.
