The mass shooting at the Mandalay Bay Resort and Casino in Las Vegas is officially the deadliest in modern American history. Unfortunately, though, it is also only one of many mass shootings that have scarred American life within the past few years.

Indeed, since the assassination attempt on a Democratic congresswoman in Arizona at the start of 2011, there have been 18 mass shootings in this country that captured national headlines.


1/8/2011 - Jared Lee Loughner, 22, killed 6 and wounded 11 others in Tucson, Ariz.

President Barack Obama called for stricter federal gun control laws after the incident, but no new federal gun laws were passed.

9/16/2013 - Aaron Alexis, 34, killed 12 people and injured 3 others in Washington, D.C.

4/2/2014 - Ivan Lopez, 34, killed 3 people and injured 16 others in Fort Hood, Texas.

6/18/2015 - Dylann Roof, 21, killed 9 people in Charleston, SC

Roof was motivated by a white supremacist ideology to open fire in a predominantly African-American church in Charleston, S.C.

The FBI later admitted that Roof should not have been allowed to buy a gun, but he slipped through the cracks.

7/16/2015 - Mohammod Youssuf Abdulazeez, 24, killed 5 people and wounded 3 others in Chattanooga, Tenn.

Mateen engaged in a mass shooting at a popular gay night club called Pulse. Until Sunday, this was the deadliest mass shooting in American history.

No new federal gun laws were passed, despite President Barack Obama urging Congress to either enact or renew laws that would ban the possession of assault-style weapons and high-capacity ammunition magazines. Mateen committed his attack with an AR-15 semiautomatic rifle.

10/1/2017 - Stephen Paddock, 64, killed at least 58 people and injured at least 515 others in Las Vegas, Nev.

It is unclear what type of weapon Paddock used during the mass shooting, although the sheriff said police found at least 10 rifles in his room. If it turns out that Paddock did use a semiautomatic weapon, however, it could raise concerns for legislation banning them.
