Colorado Authorities Release Minute-by-Minute Account of Columbine School Shooting
LINDA STOUFFER, CNN ANCHOR: Colorado authorities have released a minute-by-minute account of the gruesome events inside Columbine High School the day two gunmen killed 13 people then later themselves. What the report doesn't offer is an explanation for what may have motivated the attack, and that has the victims' families still searching for answers. With more, here's CNN's Tony Clark.</s>TONY CLARK, CNN CORRESPONDENT (voice-over): Brian Rohrbough, whose son was killed at Columbine, started wading through the computerized report almost as quickly as he got it.</s>BRIAN ROHRBOUGH, SHOOTING VICTIM'S FATHER: a lot of it seems pretty vague to me.</s>CLARK: Dale Todd, whose son was wounded, still has unanswered questions about the gunmen.</s>DALE TODD, SHOOTING VICTIM'S FATHER: What belief system did they have that allowed them to harbor so much hate, to turn into such demonic little warlocks.</s>CLARK: The Columbine report says Dylan Klebold and Eric Harris' killing rampage lasted only 16 minutes. It was far different than they had planned. This duffel bag contained one of two homemade bombs created from 20-pound propane tanks. According to a timeline from the sheriff's office, their plan was for the bombs to explode in the cafeteria and kill more than 400 students and teachers. A page from Dylan Klebold's notebook says, "When the first bombs go off, attack. Have fun." With these four weapons and hundreds of rounds of ammunition, they were to wait outside to shoot those who survived the blast as they ran from the school. But the bombs didn't explode. The plan changed, and they began shooting their way into Columbine.</s>OPERATOR: What's your name, ma'am?</s>UNIDENTIFIED FEMALE: I'm Patti.</s>OPERATOR: Patti?</s>UNIDENTIFIED FEMALE: (OFF-MIKE)</s>CLARK: A security camera shows the gunmen next in the cafeteria, trying to get their bomb to explode by shooting at it. When that didn't work, they appeared to leisurely walk around. Despite the report's findings that Klebold and Harris's victims were already shot at this point, some parents were upset that authorities didn't act more quickly to stop them.</s>JULIE BROWN, COLUMBINE STUDENT'S MOTHER: They let the killers take over our school. They stood outside. They let this happen.</s>CLARK: According to a witness in the cafeteria, one of the gunmen said, today the world is going to come to an end. Today is the day we die. Shortly after noon, after exchanging shots with police, Klebold and Harris returned to the library and killed themselves. (on camera): While the report describes the Klebold and Harris as essentially loners, it does not explain what turn them into killers. Tony Clark, CNN, Jefferson County, Colorado.
