For thieves with a huge stomach ache: A Seattle patrol officer discovered a 30-foot Dreyer's Ice Cream truck in South Seattle that had been stolen earlier Monday from Shoreline. The driver reported the theft to the King County Sheriff's Office just before 3 p.m. Monday. He left the vehicle for a few minutes at a Walgreens store at 14510 Aurora Ave. N. and returned to find it gone. The truck was found just before 11:30 that night on a South Seattle street. "I understand most of the ice cream was still there," sheriff's Deputy Travis DeFries said.
