A man shot by a Gwinnett County officer called 911 to report that he had been injured, police said Friday night. Police were quickly able to render aid to the man because they were just outside his Buford home.

Officers were called to the 4600 block of Gold Mine Drive in Buford around 4:15 p.m. on a report of gunshots being fired, according to Sgt. Rich Long with Gwinnett police.

At the home, officers were told that Jon Christopher Digiulio, 42, had been involved in a dispute with his roommates Thursday, Long said. But Digiulio, who is wheelchair bound, declined to come out of the house, according to police.

Around 5 p.m., Digiulio allegedly fired several shots out of the house, but no one was injured. At that point, a SWAT team was activated, Long said.

“SWAT team members were in place at about 6:05 p.m. when the suspect fired additional shots from a window towards officers that were stationed outside,” Long said in an emailed statement. “When the suspect reappeared in the window with a gun at about 6:30 p.m., an officer fired a single shot, striking the suspect.”

After being shot, Digiulio called 911 stating that he was injured and asking for help, Long said. The SWAT team confirmed the Digiulio was no longer armed before an officer rendered first aid. Digiulio was then transported to a local hospital for treatment, according to police. He was in stable condition with an injury to his hand, Long said Saturday.

An arrest warrant has been issued for Digiulio on an aggravated assault charge, police said. Digiulio will remain under guard until his release, Long said.

The officer who fired the shot will be placed on administrative leave per police department protocol. His name has not been released.

The incident remains under investigation.
