Tow truck operator, Joe Fairbourn, spent an hour and a half digging Susie Harris' car out of the mud Friday afternoon when it rolled into the construction site of the Broadway Theater parking garage on 300 South and Edison Street in downtown Salt Lake City. Harris thought her Toyota Camry had been stolen when she came out of a downtown business about 3:30 p.m. and it was gone. Her car had apparently slipped out of gear and rolled about 100 yards down an alley and into the muddy construction site."The car came crashing through the gate and rolled down the hill before it stopped," said crane operator Steve Prout. "It was going fast enough to break the mirror on the car." No one was injured.
