54-year-old Dave O'Quinn, of Moore, Oklahoma, barricaded himself inside his home Tuesday afternoon. He called his sister and threatened to shoot himself, which resulted in a standoff with police. According to police, "As the SWAT team was making entry we had an accidental discharge by one of the members, striking one of the officers in the leg, the lower part of the leg. Once that was taken care of they continued on and made entry into the house and found that the person inside suffered a gunshot wound to the head."
The officer, Sgt. Michael Leonard, was struck in the leg with a round from an AR-15 rifle. He was taken to the hospital for surgery and is expected to be okay.
O'Quinn is alive but in critical condition.
