Calif. cop shot, killed by fellow officers during arrest The officer, who was manning a DUI checkpoint at the time, was arrested for sexual misconduct with a teenage minor January 29, 2012 Associated Press SANTA MARIA, Calif. — A police officer under investigation for sexual misconduct with a teenage minor was shot and killed while on duty by fellow officers Saturday as they tried to arrest him on California's central coast, authorities said. The officer was manning a DUI checkpoint when the shooting occurred shortly after 1 a.m. He was declared dead after emergency surgery at Marian Medical Center, Santa Maria police Chief Danny Macagni said in a statement. The officer, a four-year Santa Maria department veteran, had just learned of the internal investigation of an alleged sexual relationship with a 17-year-old girl, and it became necessary to arrest him immediately, Macagni said. "We had no choice," Macagni said in video of an afternoon news conference posted by KCOY-TV. He said investigators had evidence "that demanded that we go out and take this officer off the street immediately."
