A Vacaville man crossing an item off his to-do list Wednesday unexpectedly added another one when he accidentally shot himself outside a Callen Street gunsmith shop and was transported to a nearby hospital.

The victim, a 27-year-old Travis airman, was shot in the leg, Vacaville police Acting Lt. Bryan Larsen said. “His injury does not appear to be life threatening,” he advised.

Around 10:45 a.m., officers responded to the 1300 block of Callen Street for a report of a gunshot victim. Officers found the wounded man inside Goodshots Gunsmithing.

Vacaville firefighters subsequently carried the victim, who was conscious and alert, out on a stretcher. He was transported to Kaiser Permanente Vacaville Medical Center for treatment.

Meanwhile, officers cordoned off the scene as investigators began their probe.

As officials from Travis Air Force Base arrived on scene, a representative of the county’s Humane Animal Services arrived to take custody of the victim’s dog, which appeared to be a young black German Shepherd. The dog’s bark was huge but the pup turned out to be friendly and was placed into the care of a Travis official.

Richard Nola Jr., gunsmith shop owner, waited on the sidewalk as police conducted their investigation.

He explained that the victim had called the shop asking to bring his firearm in and have work done on its sights. He later showed up, placed the firearm on the shop counter and said he was hurt.

“He said he felt pain,” Nola said, adding that the man asked permission to use the restroom to check the injury site. He came out and asked for an opinion on the bleeding injury.

“We said that’s a gunshot wound,” Nola recalled. “You could see the circle.”

The owner of the shop next door had told Nola that a “pop” was heard outside prior to the melee.

The victim reportedly said he had no idea how the shooting occurred.

Hours later following the investigation, police revealed that the handgun used in the shooting was found at the scene.

“After evaluating all the physical evidence located at the scene, the victim’s injury, and his statement it was determined he accidentally shot himself in the leg,” officials said in a press statement. “He was at this business to have his firearm serviced, but didn’t properly unload it.

“This case is an example of the importance of always treating a firearm as being loaded and making sure to visually and physically inspect it before taking it in for service.”
