A police pursuit through Placer County ended at the Interstate 80, Highway 65 interchange. That’s where the gunman’s pickup truck ended up after colliding with multiple vehicles during the pursuit. He was killed after shots were exchanged with numerous officers. “Multiple officers from multiple jurisdictions were involved in not only the shooting but in the entire incident,” said Roseville police Officer Rob Baquera. It began in Newcastle, where witnesses saw a pickup truck pulling a trailer with a motorcycle on it speeding in tight circles. “He started going in circles and my friend goes, ‘You got to watch this guy doing donuts over here,'” said nearby business owner Rod Engberson. “We didn’t know he had a gun. We just thought he was trying to lose a motorcycle off a trailer.” The suspect then parked the pickup in front of Engberson’s business for 15 minutes. Engberson called 911 but before deputies arrived he heard gunfire. “Some say two clips, I heard three,” Engberson recalled. What the suspect was shooting at is still unknown. Afterward, he slowly and calmly drove away. But he apparently wasn’t finished. He traveled down Rock Springs Road in Penryn where 93-year-old Mary Toste was found shot to death in front of her home. The gunman then shot and injured a man in a vehicle. The victim drove to a Loomis fire station for aid. Another driver was shot at but wasn’t hit. A resident on Rock Springs said the suspect parked directly in front of her house for several minutes before firing his gun. She and her young children had to dive for cover. “There are seven crime scenes that we’re looking at right now throughout south Placer County and it’s going to take some while to get down into those details,” said Placer County sheriff’s Lt. Andrew Scott. Investigators are still trying to determine a motive and whether any of the victims knew the suspect. Right now, they believe they were random acts of violence. A K-9 officer was shot during the gunfight but is recovering, as is the motorist who was shot and injured. So far the name of the dead suspect has not been reported.
