Adam Lanza, the suspected shooter of a Newtown, Conn. elementary school Friday, reportedly had an “altercation” with four school staff members the day before the attack, law officials tell NBC News:
Three of the four staff members were killed Friday in one of the worst school shootings in U.S. history. The fourth staff member was not at school that day and is being interviewed by federal and state investigators, NBC News’ Pete Williams said.
Two days before that, Adam Lanza, 20, went to a sporting goods store in Danbury, Conn., and tried to purchase a rifle, but was rebuffed because the state has a waiting period for gun sales, the officials said.
