The 911 dispatcher told him to administer CPR, but Mr. Reichert, who has had emergency training, told her it was too late. His son, Kameron, 17, was already cold to the touch.

 

Guns are like a grandmother’s diamonds in the Reichert family, heirlooms that carry memory and tradition. They are used on the occasional hunting trip, but most days they are stored, forgotten, under a bed. So when Kameron used one on himself, his parents were as shocked as they were heartbroken.

“I beat myself up quite a bit over not having a gun safe or something to put them in,” Mr. Reichert said. But he said even if he had had one, “There would have been two people in the house with the combination, him and me.”
