 It took 20 years, but Phoenix police solved the cold case going back to 2003 with the arrest of the suspect. Sergeant Brian Bauer says police arrested 37-year-old Sergio Reyes for the murder of 15-year-old Elena Laswell. He's accused of killing the girl in her bedroom July 10th, 2003. Years passed without knowing his whereabouts, then police enlisted some help. They started working with the U.S. Marshal Service, with Mexico, believing that he had fled down to Mexico. They were able to locate Sergio down in Mexico.
