Hunter said she and another neighbor immediately suspected Sally's son Ryan when they realized where the gunshots came from. Ryan had a temper and had sometimes thrown tantrums in high school, rushing outdoors hollering and throwing things.
His truck was in the driveway Saturday.
"We went, 'Oh my God, he shot her,'" Hunter said. The neighbor ran to the house in her flip-flops and shorts, pounding on the door to try to save Sally. But nobody answered. Smoke could be seen coming from a window.
The Carnan family home is on about 2 acres, and while many neighbors own horses, the Carnans do not. Their backyard featured a professional-style paintball course.
"They didn't have horses, they played paintball," Hunter said. "Their whole backyard behind the steep hill was set up with the wood plywood boards to hide behind. He was a good aim ... between paintballing and the military."
Police said Monday that Carnan carried a handgun with him, and he had advanced firearms skills and training. They declined to say whether it was registered to him or legally in his possession.
Hunter said Carnan had a temper problem but there were no indications he'd take such drastic actions. Often he'd be spotted out mowing the grass or at local garage sales.
"The mother loved her son, for whatever problems she had, she was there for him," Hunter said. "It was a tragedy it happened."
