ELIZABETHTOWN, N.C. (AP) -- A North Carolina sheriff's office says a firefighter has died after falling 15 feet from the roof of a water rescue building.

The Bladen County Sheriff's Office confirmed in a Facebook post Tuesday that 37-year-old Mildred Gray Williams was working her day job with a construction company to replace the Bladen County Water Rescue building's roof when she fell.

She was a volunteer with both the White Lake Fire Department and the water rescue team but wasn't on duty at the time.

Sheriff Jim McVicker said that following procedure, the accident has been reported to the Labor Department for investigation.
