A police officer was killed in Indianapolis Thursday by a crash victim he was trying to help, police say. Authorities say Lt. Aaron Allen was shot multiple times after approaching a car that had flipped in an accident on the city's south side Thursday afternoon, the Indianapolis Star reports. Another officer responding to the crash and an off-duty officer who was in the area returned fire, injuring the shooter, police say. Both people who were in the flipped vehicle were taken to a nearby hospital with non-life-threatening injuries and are now in police custody. Allen, 38, was pronounced dead at the same hospital.
A witness tells RTV6 that the driver was trapped upside-down in the overturned vehicle when he opened fire for reasons that are still unclear. The witness says at least 20 shots were heard. Allen, the Indianapolis-area Southport Police Department's officer of the year in 2015, leaves a wife and children, CBS News reports. He had been in law enforcement for almost 20 years. He was "a hard worker and today was no different," Southport Police Chief Thomas Vaughn told reporters Thursday. "He responded to a crash with urgency to preserve life and tragically his was lost." (A slain NYPD officer became a father this week, more than two years after his death.)
