No one is facing criminal charges in connection to the shooting death of a 24-year-old Denver man that occurred at a campground near Allenspark over Memorial Day weekend, and the case has been ruled an accident, according to Boulder County sheriff's officials.

David Munoz-Tarin died after suffering a gunshot wound to the face at 1:15 a.m. May 28 at the Olive Ridge campground northwest of Boulder, according to the Sheriff's Office.

Sheriff's deputies initially responded to a report that a man had shot himself accidentally. Munoz-Tarin had been camping and shooting guns with friends at the campground when he was shot, according to sheriff's officials.

The Boulder County Coroner's Office late last month ruled that the cause of Munoz-Tarin's death was a gunshot wound to the head but did not rule the death a suicide, homicide or accident, classifying it instead as "undetermined."

Cmdr. Rick Brough of the Sheriff's Office said investigators determined the shooting was an accident after talking with three friends that were with Munoz-Tarin when he was shot.

Munoz-Tarin had a handgun with him at the time of the incident that investigators determined he believed only had four bullets in it, which meant that each member of the camping party, including himself, would get to fire one shot before the gun was empty, Brough said.

Once each person had fired the gun May 24, the victim went to take the gun from a friend's hands, at which point it went off and struck him in the face, Brough said.
