(AP) -- Mass shooters have killed hundreds of people throughout U.S. history in realms like stores, theaters and workplaces, but it is in schools and colleges where the carnage reverberates perhaps most keenly — places filled with children of tender ages, older students aspiring to new heights and the teachers planting the seeds of knowledge, their journeys all cut short.
If a mass shooting is defined as resulting in the death of four or more people, not including the perpetrator, 169 people have died in 14 such events connected to U.S. schools and colleges — from 1999's Columbine High School massacre to Tuesday's shooting in Texas. That's according to a database compiled by The Associated Press, USA Today and Northeastern University, and to other AP reporting:

Even as President Biden's party has slim control of Congress, gun violence bills have stalled in the face of Republican opposition in the Senate. Last year, the House passed two bills to expand background checks on firearms purchases, but both languished in the 50-50 Senate where Democrats need at least 10 Republican votes to overcome objections from a filibuster.
"It sort of centers around the issue of mental health. It seems like there's consensus in that area," No. 2 Senate GOP leader John Thune said about how Congress should respond to the Uvalde shooting. He did not specify what that would be.
In Texas, any changes to gun access would not come until lawmakers return to the Capitol in 2023. In the past, calls for action have faded.
