The mass shooting as Jason Aldean performed at a country music festival in Las Vegas is now the deadliest such incident in modern American history.
It eclipsed the 2016 Pulse nightclub massacre in Orlando as the worst event of its kind.
These are the deadliest mass shootings on U.S. soil:
Around 10 p.m. Sunday (1 a.m. ET), gunman Stephen Paddock opened fire from the 32nd floor of the Mandalay Bay Resort on a crowd watching Aldean. Several weapons were located in the 64-year-old Paddock’s hotel room. Police reported more than 50 people were killed and more than 400 people were injured in the shooting.
On June 12, 2016, 49 people were killed and dozens more were wounded after gunman Omar Mateen opened fire and took hostages at Pulse, a LGBT-friendly nightclub in Orlando, Florida. He was later killed following a standoff with police. Mateen was a lone-wolf shooter, using a rifle and handgun he’d purchased legally, according to authorities.
On April 16, 2007, Virginia Tech student Seung-Hui Cho shot 32 people to death on the Blacksburg, Virginia, campus before killing himself. Another 17 people were injured. Days after the worst school shooting in the nation’s history, NBC News received a package from Cho, 23, that contained a video of him ranting about rich “brats” and complaining about being bullied.
On Dec. 14, 2012, 20-year-old Adam Lanza killed 27 people, including his mother, 20 elementary school kids and six school staff and faculty at Sandy Hook Elementary School in Newtown, Connecticut. He also took his own life. Lanza suffered from extreme mental health issues that weren’t treated, and was preoccupied with violence, a report from state officials found. He also had easy access to weapons, the report said.
On Oct. 16, 1991, a 35-year-old named George Hennard crashed his pickup through Luby’s Cafeteria, a packed restaurant in Killeen, Texas. He shot and killed 23 people before turning the gun on himself. Twenty-seven others were wounded. According to a former roommate, Hennard “hated blacks, Hispanics, gays. He said women were snakes.”
On July 18, 1984, James Huberty, a 41-year-old former security guard who had lost his job, opened fire at a McDonald’s in San Ysidro, California. He killed 21 employees and customers, including children. A police sniper killed him an hour after he started shooting.
On Aug. 1, 1966, former U.S. Marine Charles Joseph Whitman, 25, killed his mother and wife, then went on top of a tower at University of Texas at Austin and killed 16 others. He also wounded at least 30. Whitman had complained of physical and mental health issues before the attack. He was then shot by a police officer. An autopsy after his death revealed he had a brain tumor, but it was not clear whether that had affected his actions.
