Gun control activists rally in Nashville, Tennessee on March 28, 2023, following a school shooting, where three students and three staff members were killed on March 27. A heavily armed former student killed three young children and three staff in what appeared to be a carefully planned attack at a private elementary school in Nashville on March 27, before being shot dead by police.

Chief of Police John Drake named the suspect as Audrey Hale, 28, who the officer later said identified as transgender.

Three people died and five others were injured after a shooting at multiple locations on Michigan State University's East Lansing campus on the night of Feb. 13. The suspect died from a self-inflicted gunshot wound, officials said.

An 18-year-old gunman opened fire On May 24, 2022, at a Texas elementary school, killing 19 children and two teachers and wounding others, Texas Governor Greg Abbott said at the time. It was the deadliest shooting since the attack at Sandy Hook Elementary school a decade ago. 

On May 18, 2018, Dimitrios Pagourtzis, 17, opened fire on fellow students and school staff, killing 10 people in one of the deadliest school shooting incidents in the United States at the time.

The Sandy Hook Elementary School shooting occurred in Newtown, Connecticut, when 20-year-old Adam Lanza shot and killed 26 people. Twenty of the victims were children between six and seven years old, and the other six were adult staff members. Earlier that day, before driving to the school, Lanza had shot and killed his mother at their Newtown home. As first responders arrived at the school, Lanza died by suicide, shooting himself in the head.

This has been the deadliest school shooting in the United States in a decade.
