Police are looking for a knife-wielding robber who took OxyContin and sunglasses from a drugstore early Sunday in Salt Lake City. About 1:30 a.m., a man with a knife in his hand jumped over the pharmacy counter at Walgreen's, 909 E. 2100 South, said Salt Lake City police Lt. Dave Hoffman. The man demanded and received OxyContin before he attempted to leave. Someone in the store ordered the robber to stop because he also had taken a pair of sunglasses. The robber told the victim to turn around or he would shoot the victim, Hoffman said. The man was described as white, 5 feet 6 inches tall, 150 pounds, with light brown hair, a black baseball cap, black jacket and blue jeans.
