Steven Dixon was 16-years old when he allegedly stabbed Tiffany Lindsey to death in October 1991. She was also 16.
Prosecutors say Dixon told detectives he was at Lindsey's South Side apartment when someone stabbed both of them.
Two years ago, police realized that DNA saved from the case was never analyzed. Testing found Dixon's blood on Lindsey's fingernails and a weapon recovered at the scene. He's now being held without bond.
