April 22, 1992 - Adam Lanza

Adam Peter Lanza (April 22, 1992 – December 14, 2012) was an American mass murderer responsible for the Sandy Hook Elementary School shooting, one of the deadliest mass shootings in the US. On December 14, 2012, he fatally shot his mother, Nancy Lanza, at their home in Newtown, Connecticut, before driving to Sandy Hook Elementary School, where he killed 20 children between the ages of six and seven, and six adult staff members.

Lanza was born in Exeter, New Hampshire, and grew up in Newtown, Connecticut, where he was raised primarily by his mother following his parents' divorce in 2008. From an early age, he was diagnosed with a number of neurodevelopmental conditions, including Asperger syndrome, sensory processing disorder, and obsessive-compulsive disorder. He was described by those who knew him as highly intelligent but profoundly withdrawn. He struggled throughout his childhood and adolescence with social interaction and emotional regulation.

As a teenager, Lanza became increasingly isolated and stopped attending school. His anxiety led to him being placed on homebound status, where he received instruction at home rather than attending classes.
