On Dec. 14, 2012, Adam Lanza, 20, walked into the elementary school and started shooting, CNN reported. The weapons were legally purchased by his mother Nancy Lanza, whom he killed at their home before he went to the school. As police approached him that day six years ago, Lanza killed himself.

On Friday, a bomb threat was made toward the school around 9 a.m. forcing the evacuation of the building that sits on the site of the massacre. The other school was torn down and replaced by a new structure, The Associated Press reported.
