A Los Angeles driver for Uber and Lyft has been missing for days and police have asked the public for help. Joshua Thiede was last seen Feb. 11 in Los Angeles, the LA Times reports. The 29-year-old's mother, Janet Thiede, said phone records show that somebody called 911 from her son's phone on Feb. 12, but the call was disconnected before the dispatcher picked up, reports CBS Los Angeles. The phone is no longer active, per NBC Los Angeles. Janet Thiede says her son, an Ohio native, has been driving for the ride services while working on a business plan to sell organic shoes. His car also is missing, and friends were passing out fliers Sunday hoping for leads on his whereabouts. (More Uber stories.)
