A Denver police officer will face 10 days of suspension without pay for almost shooting a man in the head by accident.

Officer Asher Rose will begin his suspension on Feb. 25 for firing his gun accidentally while trying to turn on the flashlight mounted to the weapon, according to a disciplinary letter obtained by The Denver Post. The bullet struck inches from the head of the man he was attempting to arrest, the letter states.

The incident happened more than a year ago, but the internal administrative investigation didn’t begin until November because the police department’s Use of Force Board was reviewing the incident previously.

Around 7:30 p.m. Dec. 15, 2017, Rose and Officer Alicia Martinez received a call about an allegedly drunk person attempt to stop vehicles traveling on West Evans Avenue in south Denver, according to the letter. The caller stated that the man had entered one car, but pedestrians were able to pull him out.

The two officers arrived at the scene and found the suspect running behind nearby warehouses.

Rose ran after the suspect, who is not named in the document, while Martinez drove the patrol car to where the suspect was. While driving, Martinez heard a gunshot.

Martinez quickly got out of the car and found Rose trying to coax the suspect out from underneath a truck where he was hiding. Rose told Martinez and other officers who arrived shortly afterward that he had fired the shot on accident. Footage from Martinez’s body-worn camera showed that the bullet had struck one of the tires inches from where the suspect’s head had been.

The suspect was unharmed and police officers arrested him.

Rose later said that he “unintentionally discharged a round as he was turning on his weapon-mounted light,” according to the disciplinary letter. He immediately informed supervisors and has taken responsibility for his actions, the letter states.

The internal review of his actions found that he had handled the gun carelessly and had his finger on the trigger though he did not intend to shoot.

Rose joined the department in January 2017 and had no previous disciplinary issues, the letter states.

Multiple accidental shootings in 2014 that police said were caused by mounted flashlights prompted a review of the equipment. The department had already banned a certain design of such flashlights with switches below the trigger.
