The FBI has caught an escaped prisoner who had been on the run for 36 years -- and it's largely because his dying mother had asked to see him, CNN reports.
"She asked various family members to assist her in using the 'secret' number to call 'Billy,'" the FBI said. Agents had been tipped off about the conversation by a source.
Armed with that information, agents scoured phone records of people who they believed may have helped fulfill the mother's request.
