Aaron Richmond Bornemann, 23, was killed in Bellingham, Washington, on the evening of April 2, 2015, after a handgun discharged during what friends described as ‘‘messing around’’ with the weapon. Bornemann had gone to a friend’s house and brought a .22-caliber pistol. Reports say the men removed the magazine and dry-fired the gun inside the home; later, after stepping outside for a cigarette and returning, the friend picked up the handgun, pointed it at Bornemann’s head believing it to be unloaded, and pulled the trigger. The shot was fatal; Bornemann was taken to St. Joseph hospital and never regained consciousness. An autopsy found alcohol and illegal drugs in his system, and investigators suggested Bornemann may have reloaded the gun without the other man’s knowledge.

Masen Jon Potter, 22 at the time, confessed to police, was arrested shortly after the shooting, and was charged with first-degree manslaughter. He later pleaded guilty to that charge; in March 2016 a judge sentenced him to five years and ten months in prison under a plea agreement that had been discussed with Bornemann’s family. Does anyone have additional information about the events that night or knew Aaron and his circle of friends?
