The woman shot by her suburban Atlanta police chief husband early New Year’s Day told investigators she was sleeping at the time and believes the shooting was accidental, Georgia investigators said.

Margaret McCollom, 58, remains hospitalized in good condition, five days after her husband William McCollom, the Peachtree City, Ga., police chief, told a dispatcher he accidentally plugged her – twice – with his service weapon around 4:15 a.m. Jan. 1.

Investigators later learned Margaret had been shot just once after she was taken into surgery.

It’s unclear if William McCollom fired the weapon twice, or why exactly he told the 911 dispatcher that his prone wife had been hit twice.

The chief is on leave as the Georgia Bureau of Investigation looks into the shooting. The GBI released Friday the 5-minute 911 call made by William McCollom shortly after he shot his wife.

"The gun was in the bed. I went to move it, put it to the side, and it went off," he says in the call placed at 4:17 a.m.

He later says he was asleep at the time of the shooting and then tells the dispatcher the gun is on a dresser.

Margaret McCollom can be heard crying in the background, lying on her stomach in their bed, while her husband tries to console her.

"Are you alright dear? I know you're not all right, I mean, are you still breathing?" he’s heard asking his wife.

William McCollom is glum on the call as he admits he’s also the local police chief.

"She's having trouble breathing," he tells the dispatcher as his wife is heard crying in the background. "How the hell did this happen?" he says in an aside.

No charges have been filed.

William and Margaret McCollom were divorced in 1999 before apparently reconciling, the Associated Press reported. He spent two decades as the Delray Beach, Fla., police chief before moving to a smaller department. William McCollom was hired by Peachtree City in 2012 and reportedly became chief in October after serving some months as the interim chief.
