Playing Here Are the Deadliest Shootings in U.S. History

Twenty-six people have been killed and another 20 more were injured when a gunman opened fire during morning worship at a church in Sutherland Springs, Texas, Sunday.

Devin Patrick Kelley, who was wearing all-black tactical gear and a mask, opened fire outside the First Baptist Church at about 11:20 a.m. local time before entering the church and continuing to shoot, according to authorities. The gunman fled in a car and was later found dead with a gunshot wound.

Among the dead are children, a pregnant woman and the 14-year-old daughter of the church's pastor, according to reports.

The massacre is the deadliest mass shooting in Texas' modern history and the deadliest in an American place of worship, surpassing the killings at the Emanuel African Methodist Episcopal Church in Charleston, S.C., in 2015. That attack left nine dead.

While the death toll in Texas is still preliminary, the tragedy appears to be the fifth deadliest shooting in U.S. history, behind the Sandy Hook Elementary School massacre, which left 27 dead.

It comes just a month after the deadliest shooting in modern American history.

32 Killed in the Virginia Tech Shooting on April 16, 2007

Virginia Polytechnic Institute and State University student Seung-Hui Cho fatally shot 32 people — including 27 fellow students and five faculty members — and injured 17 others in two separate attacks on the Blacksburg campus before turning the gun on himself.

After the shooting, NBC News received writings, photographs and video that Cho sent the station, in which the 23-year-old gunman complained about being bullied and ranted about “brats.”

The American Psychiatric Association urged the media to stop airing his so-called manifesto, saying in a statement: “The publicity of the Cho materials not only seems insensitive to the grieving and traumatized families, friends and peers of those murdered and injured, but also seriously jeopardizes the public’s safety by potentially inciting 'copycat' suicides, homicides and other incidents.” 

27 Killed in the Sandy Hook Elementary School Shooting on December 14, 2012

Gunman Adam Lanza killed 20 first-graders, all ages 6 and 7, as well as six adult staff members and himself at Sandy Hook Elementary School in Newtown, Conn.

Before opening fire at the school, Lanza shot and killed his mother, Nancy Lanza, in their Newtown home. The 20-year-old’s motive for targeting the school was never established.

Lanza suffered from extreme mental health issues that were left untreated and he was preoccupied with violence, a report from the Office of the Child Advocate found.

"[Lanza], who over the years engaged in recreational shooting activities with both of his parents, retained access to numerous firearms and high capacity ammunition magazines even as his mental health deteriorated in late adolescence," the report said.

Twenty-three people were killed and 27 others were wounded in what was, until Oct. 1, the U.S.’s deadliest shooting to occur outside a school.

The attack – which including an attempted bombing – left 14 dead and 22 injured.

Farook, who was U.S.-born with Pakistani descent, and Malik, a Pakistani-born permanent resident of the U.S., were declared "homegrown violent extremists" by the FBI, but were not directed by any terrorist organizations. 

Their family learned what they did when Farook and Malik did not return to collect their daughter. A year after the shooting, Farook's sister Saira Khan, filed to adopt the little girl.
