Serial Killer Confesses to 1986 Cold Case Murder

A nearly-40-year-old cold case has been closed, authorities say because of DNA technology. In 1986, 19-year-old Cathy Small was found dead on a road in South Pasadena. Investigators say she was stabbed and strangled, but her killer wasn't identified at the time. Renewed interest in the case in recent years led to DNA testing of the evidence in Small's file. While two different male DNA profiles were present, one came back with a match. Inside Edition Digital’s Mara Montalbano has more.
