Smith told authorities he saw Brady begin descending the basement steps, then fired once Brady's hips came into view. Brady fell.
"He's looking, facing up at me, and I shoot him in the face. I want him dead," Smith told investigators.
Smith said he put Brady's body on a tarp so he wouldn't get blood into his carpet, dragged it into his
workshop, reloaded his rifle and sat down.
Smith described feeling adrenaline, and "blood was pounding in my ears." He said he also felt he was being ganged up on, something he called one of his "red buttons." So when he saw Kifer come down the stairs minutes later, "I killed her too."
He shot her, and when he tried to "finish her off" his rifle jammed and she laughed, he said.
"I just pulled out the 22 and I shot her," he told authorities. He said he then pulled her into the workshop, but she was still gasping, so "I did a good, clean finishing shot and she gave out the death twitch."
He said he didn't call police because the teens were already dead and "just cause my Thanksgiving is screwed up I don't need to screw up yours." The next day, he asked a neighbor to call police.
Smith is a retired security engineer for the U.S. Department of State. Kifer and Brady were cousins. The two were well-known in the community, and both were involved in sports.
