Billy Jensen and Paul Holes look into the unsolved murder of Brittany Phillips. 18-year-old Brittany Phillips had just moved back to the Tulsa area a few months before she was killed in her apartment in September of 2004. Law enforcement have over 70 swabs of DNA-one with a match-but Brittany's killer still remains unknown. With the help of Brittany's mom Dr. Maggie Zingman, Billy and Paul take a closer look into the investigation.
