Sheriff Hubert Peterkin said it happened around 7:30 at 110 T.C. Jones Road.
Neighbors said 35-year-old Tommy Brown was playing basketball with his sons and was concerned because neighbor John Oliver Hill Jr., 48, was shooting a gun in the area
"And this nut from across the street - who had been outside shooting his gun - the gentleman asked him if he would quit because of all the kids outside playing. And so he took it upon his self to come over here and he just shot the man. Shot him in the head," said neighbor Lois Clairmont.
Deputies said the weapon was a .30-30 hunting rifle. The three boys who witnessed the shooting ran inside to get their mother and when she came out, Hill allegedly shot her twice.
Thalia Rebecca Mook, 35, was taken to Cape Fear Valley Medical Center where she died Sunday.
Peterkin said when his officers arrived, Hill had returned to his home on Philippi Church Road - around the corner from the Brown's house. A short standoff ensued, and Hill surrendered after about 30 minutes.
Ten weapons were seized at Hill's home.
Hill was charged with two counts of first-degree murder. He was being held without bond in the Hoke County Jail.
