We often see headlines about DNA evidence exonerating the innocent. It seems we hear less about how DNA is used to track down the guilty. In the story you're about to see, a sample found on a murdered young woman, was sent to the national data base. Twelve years after she was killed, it turned up a match. One profile out of five million, matching a man thousands of miles away. But in this case, prosecutors would need more than DNA to convict a killer.
Keith Morrison asks, will there be "Justice for Bonnie?" tonight at 10pm/9c on Dateline NBC.
