Donald W. Allen, a 66-year-old Vietnam veteran in Sand Springs, Oklahoma, was shot and killed by a police officer on April 11, 2015, after a confrontation at his home. Officers had been called earlier that morning for reports of a man firing a gun in the neighborhood. When Officer Brian Barnett arrived, Donald Allen confronted him armed with a loaded pistol.

Allen had a documented history of mental illness and, according to his wife, was a paranoid schizophrenic who had not taken medication for about a year; police records show multiple prior contacts about his mental health and past seizures of firearms from the home. A negotiator and SWAT were summoned and officers attempted de-escalation, but police say Allen exited the house, advanced toward Officer Barnett while pointing the weapon, and ignored commands to drop it. Officer Barnett fired four times, striking Allen three times; CPR was performed but Allen was pronounced dead at the scene.

The two officers present were placed on paid administrative leave while an investigation was conducted. The Tulsa County District Attorney’s Office later reviewed the case and concluded the shooting was justified; no charges were filed. Does anyone have additional information about Allen’s life or that neighborhood on the day of the shooting?
