Wenatchee Police relied on surveillance systems from two businesses and some old fashioned detective work to track down a suspect who started a dumpster fire early this week. Sgt. Brian Chance said 31 year old Liam Gainey of Wenatchee was identified as a suspect in the fire started early Sunday around 1a.m. in a dumpster behind the YWCA Thrift Store next to the Cherry Creek Radio studios on North Wenatchee Ave. Police also used video from nearby security cameras at Chelan PUD. Chance said the videos gave a clear description of the suspect vehicle and helped a patrol officer identify it as one he had stopped a few days earlier.
