Two young men wearing long black trench coats approach the school. They pull out weapons and open fire in the parking lot. They proceed inside to the school cafeteria, shooting as they walk, then upstairs to the library, still shooting. Scores of students hide in closets, bathrooms, under tables and chairs. Dozens more flee the building, hiding in bushes or sprinting to a nearby park.
Ambulances take the first wounded students to area hospitals.
Anguished parents, awaiting word on their children, gather at nearby Leawood elementary school. In small groups, students and teachers run from the building to a holding area, where they are frisked, questioned, offered medical care, and then bused to Leawood elementary to be reunited with parents. A Sheriff's spokesman estimates 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.
