Columbine is no longer one of the 10 deadliest shootings in modern US history
By AJ Willingham and Eric Levenson, CNN
(CNN) -- After Columbine, it was hard to imagine things getting much worse.
At the time, the shooting at a Colorado high school was the deadliest school attack in US history. But then came Virginia Tech, and Sandy Hook.
With 13 victims dead, it was also one of the deadliest shootings overall. But then came San Bernardino, Orlando, Las Vegas, Sutherland Springs and Parkland.
In the nearly 19 years since Columbine rocked America to its core, the country has seen so many more mass shootings that the attack isn't even among the 10 deadliest mass shootings in modern US history.
Three of the five deadliest shootings have occurred in just the last year and a half.
Below is a list of the 10 deadliest single-day mass shootings in modern US history. If the shooter was killed or died by suicide during the incident, that death is not included in the total.
