In the wake of a freeway standoff between troopers and a man in a motorhome, state investigators are taking over the case. About 2:30 p.m. Saturday, a tow-truck driver reported a suspicious motorhome on southbound Interstate 215, near 1300 South in Salt Lake City. Two males and three âyoung femalesâ were reportedly in the disabled motorhome, according to the Utah Highway Patrol. When troopers arrived, they found a man at a side door of the motorhome.
