The incident is the deadliest mass shooting in Connecticut history, and the deadliest mass shooting at an elementary school in U.S. As first responders arrived at the school, Lanza died by suicide, shooting himself in the head. Earlier that day, before driving to the school, Lanza fatally shot his mother at their Newtown home. Twenty of the victims were children between six and seven years old, and the other six were adult staff members. The Sandy Hook Elementary School shooting was a mass shooting that occurred on December 14, 2012, in Newtown, Connecticut, United States, when 20-year-old Adam Lanza shot and killed 26 people.
