SPRINGFIELD, Mo. (AP) — A southwest Missouri prosecutor has determined that a Springfield man used an officer’s gun to kill himself last year while resisting arrest.

The Springfield News-Leader reports that the shooting happened in November while Officer Kolby Helms was attempting to arrest 23-year-old Magnum Phillips and take a knife away from him at a mobile home park. A Greene County news release says Phillips grabbed Helms’ handgun, and the pair struggled over it before Phillips shot himself in the head.

The release says prosecuting attorney Dan Patterson’s investigation affirms the officer’s account. Patterson also said in a letter to the Springfield police chief that Phillips said he wanted to die.

Patterson described the case in a news release as a “stark reminder of the dangers faced by police officers.”
