SUTHERLAND SPRINGS, Texas — On April 20, 1999, an 18-year-old and a 17-year-old opened fire at Columbine High School in Jefferson County, killing 12 fellow students and one teacher before committing suicide in the school library.

The shooting and its aftermath shocked Colorado and the country.

But after a gunman opened fire Sunday in a church in Sutherland Springs, Texas, that left 26 people dead, the Columbine shooting is no longer among the top 10 deadliest single-day mass shootings in the U.S. since 1949.

Columbine is now tied for the 11th-deadliest single-day mass shooting in the U.S. with five other events.

On July 20, 2012, 12 people were killed and 58 were wounded in a shooting at a screening of the new Batman film in Aurora.

That shooting is tied for the 17th-deadliest single-day mass shooting in the U.S.

James Holmes, 24, dressed head-to-toe in protective tactical gear, sets off two devices of some kind before spraying the theater with bullets from an AR-15 rifle, a 12-gauge shotgun and at least one of two .40-caliber handguns police recovered at the scene.

On July 16, 2015, Holmes was found guilty on all 165 counts against him, 24 first-degree murder, 140 attempted murder and one count of possession or control of an explosive or incendiary device.

He was sentenced to life in prison without parole.

Of the 30 deadliest shootings in the U.S. since 1949, 18 have occurred in the past 10 years. Two of the five deadliest have taken place in the past 35 days.

If the shooter was killed or died by suicide during the incident, that death is not included in the total.
