A shot was fired yesterday in an armed robbery attempt. 911 got a cell phone around 5:00 Saturday afternoon reporting that one car was chasing and shooting at another vehicle. Deputies saw the suspect vehicle on the move. As the deputy made a stop on the vehicle, two passengers jumped out and fled on foot. The driver, Sisters resident Keith Schmidtke, 35, was arrested. In the meantime, an OSP Trooper advised citizens in the area to watch for the suspects. A short time later, one of those citizens decided to check a vacant house, found the two suspects, and held them at gunpoint until police arrived. As a result, La Pine Resident Tim Sole, 30, and Jared Pickett, 33, also of La Pine was arrested. Several guns were conficasted. Victims William Duckworth and Paulette Smith of La Pine were not injured. There were three small children with them during the incident.
