After each massacre, survivors and witnesses have echoed the words “no more” — yet mass shootings have continued to plague the U.S.

In fact, shootings only have continued to increase over the past few years.

Wednesday’s shooting at Marjory Stoneman Douglas High School is the third deadliest shooting in modern U.S. history to take place within the past five months.

It’s also the 25th fatal shooting at a U.S. elementary, middle or high school since — and including — Columbine in 1999.

Here’s a look back at the 10 deadliest shootings that the country ever has seen as the nation mourns yet another tragedy.

Authorities say gunman Stephen Paddock fired at the Route 91 Harvest Festival concert on the Las Vegas Strip from the 32nd floor of the Mandalay Bay Hotel and Casino on Oct. 1, 2017, killing 58 people and wounding more than 520 others.

It was the deadliest shooting in modern U.S. history, police said. Twenty-one victims were shot in the head, 36 died with chest and back wounds and one died of a gunshot to a leg, according to a coroner’s report.

SWAT teams who stormed Paddock’s room discovered the 64-year-old dead of a self-inflicted gunshot to the mouth, the report adds.

Virginia Tech student Seung-Hui Cho fatally shot 32 people in two locations of the school’s Blacksburg, Va., campus in April 2007, before killing himself with a bullet to the head.

Many of the victims had defensive wounds, indicating they tried to shield themselves from the gunfire, but there was no evidence that Cho struggled with any of the people he killed.

Virginia Tech’s response to the shootings by the mentally ill student caused schools nationwide to review security protocols.

On Dec. 14, 2012, Adam Lanza, 20, shot his mother dead in her home, then drove to Sandy Hook Elementary School and fatally shot 20 children, between the ages of 6 and 7.

Lanza also murdered school personnel, killing a total of 26 people, before committing suicide.

“In fewer than 11 minutes, twenty first-grade pupils and six adults had lost their lives,” a police report released after the massacre reads.

 (On Nov. 5, 2017, gunman Devin Patrick Kelley opened fire at First Baptist Church in Sutherland Springs, Texas, killing 26 people.)

On Nov. 5, 2017, gunman Devin Patrick Kelley opened fire at First Baptist Church in Sutherland Springs, Texas.

He killed 26 people, including an unborn baby, and injured another 20.

Kelley, 26, died of an apparent self-inflicted gunshot wound after he was shot and chased by two men who heard the gunfire at the church and chased after him in a vehicle.

Investigators said the attack appeared to stem from a domestic dispute involving Kelley and his mother-in-law, Michelle Shields, who sometimes attended services at the church. Kelly sent several disturbing text messages to Shields prior to the shooting.

“I suggest you don’t test my resolve,” read one of several texts.

That wasn’t the first time Kelley became violent.

In New Mexico, he was kicked out of the Air Force following a court-martial in 2012 for abusing his first wife and reportedly hitting her child hard enough to fracture his skull. In Colorado, he was charged with misdemeanor animal cruelty after someone saw him punch a dog several times.

And in Texas, sheriff’s deputies were called to his parents’ house after his girlfriend told a friend he was abusing her.

“You had to walk on eggshells around him all the time because you’re afraid of saying something to upset him,” Shields told the San Antonio Express-News months after the attack.

Killeen, Texas — Luby’s Cafeteria shooting, 23 killed

George “Jo-Jo” Hennard, an unemployed merchant seaman, shot and killed 23 people and wounded 27 others during the lunchtime rush at Luby’s Cafeteria in Killeen, Texas, on Oct. 16, 1991.

Hennard killed himself shortly after the rampage.

During the attack, Hennard reportedly targeted women, whom he called “vipers.”

A shooting at Marjory Stoneman Douglas High School in Parkland, Florida, left at least 17 people dead and 15 wounded on Feb. 14, officials said.

The shooting suspect, who was identified as 19-year-old Nikolaus Cruz, had been expelled for disciplinary reasons.

The alleged gunman carried an AR-15 rifle and had “countless magazines,” Broward Sheriff Scott Israel said.

An Instagram page apparently belonging to Cruz showed pictures of guns and knives.

One student told WJXT that “everyone predicted” the shooting and some teachers acknowledged there were warning signs. However, Superintendent Robert Runcie said he was not aware of any specific warnings the school district had received regarding the shooter.
