Transcript for Off-duty officer killed by fellow cop in Russian roulette-style shooting

Now to the case in St. Louis raising many questions tonight. A police officer charged in the shooting death of a fellow officer, accused of playing a deadly game of Russian roulette. ABC’s Zachary kiesch picks up the story. Reporter: Tonight, one officer is dead and another has been charged with her death in what authorities are calling “A game gone wrong.” Police say 24-year-old Katlyn Alix was off duty and hanging out with two fellow officers when she was shot and killed early Thursday morning. Two of them were allegedly playing with their service weapons at the apartment of 29-year-old officer Nathaniel Hendren, seen here at his 2017 graduation ceremony. According to prosecutors, Hendren produced a revolver and initiated a game in which the gun’s cylinder is emptied, then a bullet is put back in the gun. In what sounds like a game of Russian roulette, the two colleagues allegedly exchanged turns pointing the gun at each other and pulling the trigger when Hendren allegedly fired the fatal shot. Police say Hendren and another male officer were on the clock when the shooting happened. As much as it saddens me and my staff to file these charges, Katlyn and her family deserve accountability and justice. Reporter: Tonight, Hendren is on administrative leave as he faces these charges. The most serious, involuntary manslaughter. Two separate investigations are going on. One is happening internally and the other one in collaboration with the Missouri state highway patrol.
