Watauga County District Attorney Seth Banks says in a statement released on Thursday that it was necessary for Deputy Adam Gregg to use deadly force in self-defense in the shooting on March 30.
The Watauga County Sheriff's Office says when Gregg spotted a suspect in some attempted break-ins east of Boone, 22-year-old Andrew John Mason attacked him. According to Banks, Mason knocked a stun gun out of Gregg's hand and began hitting the deputy him in the face and kicking him.
Banks said Mason reached for Gregg's holstered service weapon before Gregg pulled out the gun and shot Mason, who died at a local hospital.
