Gunman Had Earlier Altercation With School Staff; Unsuccessfully Tried To Buy Rifle
Adam Lanza went to a sporting goods store in Danbury, CT to buy a rifle on Tuesday, but was denied when he refused a background check or observe the state’s waiting period.
Still, Lanza was heavily armed when he forced his way into the school Friday morning – after killing his mother at their home in Newtown.
The officials said he had four handguns on him as he stormed the 600-student school and shot his victims – clustered in two classrooms – at close range. There was a rifle found in the car he drove to Sandy Hook…
The motive for the mass killing was unknown, but officials told NBC’s Pete Williams that they were investigating whether Lanza is the person who had an “altercation” with four staff members at the school on Thursday.
Three of the four 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, Williams said.
