Police 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 said that that gun was stolen.
Police sources told WSOC TV someone else stole the gun during a home break-in and later sold it to Scott.
New documents point to Scott’s extensive and violent past.
WSOC 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 his gun.
It also claimed that Scott told his family that "he's a killer and they should know that."
It went on to say that Scott has a 9 mm handgun that he did not have a permit for it and that he is a convicted felon.
The order was dismissed a month later when Scott's wife said he was no longer a threat to the family.
Documents show Scott served seven years in a Texas prison for aggravated assault with a deadly weapon and a one-year, three-month sentence for evading arrests.
WSOC also uncovered another domestic violence protective order filed by his wife Rakeyia Scott. It claimed her husband stabbed her in the back, almost puncturing her lungs.
