On the anniversary of the massacre, Peter and Shelley finally went through "the stuff," reading letters of support they previously hadn't felt able to face. Peter wanted the writers to know how much their words helped him. "There was a woman whose brother shot up a church," Peter said. "Killed a bunch of people and himself. Saying how sorry she is. There was a woman whose husband stabbed and killed a child. People having Masses said for Adam." Some included phone numbers and said to call if he needed anything. Other letters were peculiar: one suggested that Adam had been drugged by the C.I.A. and forced to his acts in order to foment support for gun-control legislation. The anniversary itself felt insignificant. "It's not like I ever go an hour when it doesn't cross my mind," Peter said when we met that day.
