They proceed inside, to the school cafeteria, shooting as they walk, then upstairs to the library, still shooting. As bullets ricochet throughout the building, scores of students hide in closets, bathrooms, under tables and chairs. Some students, barricaded behind a heavy door, whisper on their terror over cell-phone calls to relatives. Dozens more flee the building, hiding in bushes or sprinting to a nearby park. Noon - Police SWAT teams find several explosive devices around the school.
Ambulances take first wounded students to area hospitals, all of whom managed to run outside.
Anguished parents, awaiting word on their children, gather at nearby Leaman elementary school. In small groups, the students and teachers run from the building to a holding area, where they are frisked, questioned, offered medical care and then bused to Leaman elementary to be reunited with parents. 4 p.m. - Sheriff's spokesman confirms as many as 25 people are dead, a combination of students and teachers. Officers searching the library find the bodies of both suspects, who apparently died of self-inflicted gunshot wounds. All bodies remain inside.
