Sandy Hook Elementary School in Newtown, Connecticut apparently became the latest addition to the list of gruesome school shootout incidents in America after Adam Lanza, 20, went into a shooting spree last Friday.

Using two handguns, Lanza barged into the school, killing 20 kindergarten pupils in a classroom and shooting 7 other school staffs to include the school principal.

Lanza reportedly shot his own mother, also a teacher, before proceeding to her school for the rampage.

The killer committed suicide after the incident.
