A 70-year-old man who accidentally shot himself in a Clarksville restaurant this month has died.

Bobby Atkinson died of a gunshot wound to the stomach on Sept. 16, five days after the incident on Sept. 11, according to a police report obtained by The Leaf-Chronicle Thursday.

At about 8:50 a.m. that day, Atkinson entered Rudy's Diner on Madison Street and started to sit down. He dropped a cloth bag on the floor. A witness then reported hearing a pop, "like a firecracker going off," the report said.

Atkinson said he'd been shot and asked for an ambulance.

When CPD officers arrived, a customer and Montgomery County Sheriff’s Office deputy were holding the man and applying pressure to the gunshot wound to the abdomen, Knoll said.

Atkinson was taken by LifeFlight helicopter to a hospital in Nashville in critical condition.

The investigation uncovered there was a Chiappa .22-caliber revolver inside a cloth bag, strapped into a holster with the hammer forward. When the bag was dropped, the hammer of the revolver struck the floor, causing it to discharge, Knoll said.

There was a distinct chip on the corner of the hammer where it appeared to have hit the floor. The man was a Tennessee handgun carry permit holder.

The case remains open, as Clarksville Police have not yet received autopsy results from the state, according to police spokesman Jim Knoll.
