Twenty-three mass shootings have occurred in the US in the year since the Sandy Hook school massacre in Newtown, Connecticut, leaving more than 100 dead across 17 states. Today marks the anniversary of the Newtown shooting, in which Adam Lanza killed 20 children and six teachers at Sandy Hook Elementary School. Lanza, who also killed his mother before leaving home for the school, reportedly had an obsession with mass murders, especially the 1999 Columbine High School massacre in Colorado, in which 13 people died excluding the two perpetrators. While there is no official definition for a mass shooting in US law, the FBI defines a mass murder as the killing of four or more people without an extended period of “cooling-off” by the perpetrator.
