LITTLE FALLS, Minn. (AP) — A Minnesota homeowner who shot two unarmed teenagers in the midst of an apparent Thanksgiving Day break-in told authorities he feared they had a weapon, but acknowledged firing “more shots than I needed to” and appeared to take pride in “a good clean finishing shot” for one teen, according to investigators.

Byron David Smith, 64, was charged Monday with two counts of second-degree murder in a criminal complaint that was chilling for the clinical way investigators said he described the shootings.

Smith told investigators he shot 18-year-old Haile Kifer several times as she descended a stairway into his basement, and his Mini 14 rifle jammed as he tried to shoot her again after she had tumbled down the steps.
