The Call Was Made Using a Cheap, Prepaid Phone

Authorities tried to trace the call, but it had been made using a cheap, prepaid phone. It wasn't fitted with a GPS tracking device that investigators could use to pinpoint the phone's exact location. However, they were able to identify the phone's owner via its number. It belonged to a 36-year-old unemployed plumber named Michael King. Authorities now know for certain that he was behind the abduction.
