North Carolina authorities said that Keith Scott had a loaded gun when Charlotte-Mecklenburg police Officer Brentley Vinson shot and killed him last week, and on Monday, sources told WSOC-TV that the gun was stolen.

Police sources said someone else stole the gun during a home break-in and later sold it to Scott.

WSOC-TV also obtained a domestic violence protective order that Scott's wife took out on him last year.

The order, filed in Gaston County, said that Scott hit his child in the head with his fist, kicked his wife and threatened to kill them with a gun. Scott had a 9 millimeter handgun that he did not have a permit for and was a convicted felon, according to the order. It also claimed that Scott told his family that "he's a killer and they should know that."

The request for a protective order was dismissed a month later, when Scott's wife said he was no longer a threat to the family.

The State Bureau of Investigation is investigating Scott's death.

Dash and body cam videos released on Saturday show Scott appearing to back away from police with his hands at his sides. However, firearms experts told WSOC-TV that the gun Scott is accused of holding was cocked and ready to fire.

"One way to look at that is that he's backing away from the car," said one expert. "But he's getting into an area where he would have a clear shot at one or two of the other police officers."

The SBI will decipher what police saw and believed in the moments before opening fire. They'll turn their findings over to the Mecklenburg County district attorney, who will decide whether to charge Officer Vinson.
