The DCSO conducted functionality tests on the deputy’s weapon and found nothing wrong.
The deputy was part of the Emergency Response Team that assisted the Durham County Bomb Squad when a motorist reported a suspicious object beside a median wall along Interstate 40.
The highway was shut down for hours while explosive experts determined the object was harmless pieces of foam taped together with a bungee cord attached.
Investigators have said the assault rifle went off as deputies were returning to a vehicle that carries special equipment for bomb investigations.
The deputy is out of the hospital but has not returned to work. He’s recovering from surgery on his arm. The bullet that wounded him is believed to be from his own weapon.
