A St. Louis, Mo., police officer has been charged with involuntary manslaughter after a fatal game of “Russian Roulette” led to the death of another officer. According to a probable cause statement released by St. Louis police on Friday, 29-year-old Nathaniel Hendren, is accused of killing fellow officer Katlyn Alix, 24, at his apartment on Thursday. Hendren, Alix and a third officer were at Hendren’s apartment when Hendren emptied the bullets from a revolver, leaving one in the chamber, the statement said.
