In the last week it seemed that Liberty Lake was the place for people to pull over and light up their marijuana pipes. Liberty Lake Police made arrests in two instances where suspicious parked cars were spotted and officers could smell the distinctive odor of the drug. In one case clouds of smoke were billowing out of the car, said police chief Brian Asmus. At 9:30 p.m. on March 5 an officer spotted a car parked on a dead-end street in the 19700 block of Shannon Ave. at a 45-degree angle to the roadway, Asmus said. When the officer approached, it was evident that the car was filled with smoke. A lot of it came out when the driver opened the door to talk to the officer, Asmus said. The driver, a 17-year-old Spokane Valley boy, was charged with possession of marijuana and possession of drug paraphernalia.
