The Oklahoma City Police Department has released a dramatic body cam video showing the intense moment officers shot an armed man in a fatal incident that began as a mental health call.

The footage is a difficult watch, as it shows Brandon Lena, in distress, walking around with a pistol outside his house near Tinker Air Force Base.

Despite the officers’ efforts to calm the situation, it escalates quickly, ending with Lena’s death in the street.

The video shows Officers James Doran, Joshua Geerdes, and Jimmy Hatfield, who are part of the Crisis Intervention Team, introducing themselves and pleading with Lena to drop the gun. However, he points the gun straight at them.

The officers fire less-than-lethal 40mm projectiles in an attempt to subdue Lena, striking him in the torso. Despite this, he continues to aim his gun at the officers, prompting them to fire more less-than-lethal rounds in a futile attempt to defuse the situation.

The officers are then heard firing multiple rounds of gunshots at Lena, resulting in his instant death.

The Oklahoma City Police Department has placed all three officers on routine administrative leave while the shooting is officially investigated.
