Philadelphia police say 22-year-old Roswell Friend was last seen Thursday evening. His mother, Regina, says he didn't show up for a job interview on Friday.
Friend, originally from Cockeysville, Md., recently graduated from Temple, where he was a member of the track team. A campus security camera captured him going for a run around 7:30 p.m. Thursday.
Police say they recovered Friend's cellphone, wallet and car keys from his house. His house keys are missing.
Investigators are asking anyone with knowledge of Friend's whereabouts to contact police.
