OAK HILL, Fla. – The Volusia County Sheriff's Office is investigating after a man said he accidentally shot and killed his longtime girlfriend while the two were camping in Oak Hill Sunday.

Authorities said that the call for the shooting came in around 5 p.m. in the area of Brooks Circle and Saturday Drive.

Officials with the Sheriff's Office said the victim, Dawn Schaefer, 53, was shot by her boyfriend, Andrew McGee, 49. McGee remained on the scene and cooperated with detectives.

Detectives said Schaefer was killed near the couple's tent in the wooded area near 232 North Brooks Circle in Oak Hill.

"McGee told detectives he heard gunshots in the area and came out of the tent to fire a warning shot in response to those gunshots," a statement from the Sheriff's Office said. "He said he slipped and accidentally shot Schaefer with an old, poorly functioning shotgun."

McGee told authorities he couldn't see Schaefer in the dark.

No charges have been filed against McGee, and the investigation is ongoing.
