(ADAM BRIMER/NEWS SENTINEL)OAK RIDGE - The accidental discharge of a firearm at the Y-12 National Security Complex occurred early Sunday when a security police officer was "repositioning" his weapon inside a hardened patrol vehicle, which he shared with another security officer.
According to the occurrence report filed by Y-12, the repositioning of the officer's "duty firearm" caused "an unintended discharge of that firearm." A single round was discharged, but it "impacted the interior wall of the hardened vehicle causing fragmentation," the report stated.
