On December 14, 2012, a mass shooting occurred at Sandy Hook Elementary School in Newtown, Connecticut, United States. The perpetrator, 20-year-old Adam Lanza, shot and killed 26 people. The victims were 20 children between six and seven years old, and six adult staff members. Earlier that day, before driving to the school, Lanza fatally shot his mother at their Newtown home. As first responders arrived at the school, Lanza killed himself with a gunshot to the head. The incident is the second deadliest school shooting in US history behind the Virginia Tech shooting in 2007.

On October 1, 2017, a mass shooting occurred when 64-year-old Stephen Paddock opened fire on the crowd attending the Route 91 Harvest music festival on the Las Vegas Strip in Nevada from his 32nd-floor suites in the Mandalay Bay hotel. He fired more than 1,000 rounds, killing 60 people and wounding at least 413 others. The ensuing panic brought the total number of injured to about 867. About an hour later, he was found dead in his room from a self-inflicted gunshot wound. The motive for the shooting is officially undetermined.
