JEFFREY KAYE: More bomb sweeps were carried out at Columbine High School today. Investigators say they'll continue to examine the crime scene for as many as two more weeks. Authorities are also carefully reviewing a diary kept by one of the suspected killers, Eric Harris, which indicated he and Dylan Klebold had planned the massacre for an entire year. According to Sheriff Spokesman Steve Davis, the diary also suggested the two intended to kill more than the 13 murdered last Tuesday.
STEVE DAVIS: It did include things such as I believe it said kill 500 people, hijack a plane and crash it into New York City. Yes, those were part of what's in the diary. We have indications in the diary that make us believe that if, in fact, they were able to carry out their entire plan, there could have been quite a bit more damage and quite a few more fatalities.
JEFFREY KAYE: Davis also said an 18-year-old female friend of one of the suspects was believed to have purchased one or two of the four weapons used in the killings.
STEVE DAVIS: Her involvement at this point is not -- I mean there's not enough evidence that we're aware of to classify her as a suspect. If, through our investigation, it is shown that she or anyone else for that matter, either supplied the weapons to the suspects, especially with knowledge of their intent, the district attorney has informed us that certainly he's leaving open the possibility of charging not only her but anyone, for that matter, that could be shown that they knew.
JEFFREY KAYE: Davis said no arrests of any suspect is imminent. Investigators are completing an inventory of evidence taken from the boys' homes. At the Harris house, they found the sawed off barrel of a shotgun and bomb-making materials in clear sight. The discoveries prompted an outraged response by Jefferson County Sheriff Johnstone who said, "I think I would be a little concerned about my son's room if I went in there and I found a sawed-off shotgun barrel. I think parents should be accountable for their kids' actions." But the sheriff's spokesman refused to comment on reports that parents of another Columbine High School student went to the department last year to complain that Harris was making pipe bombs.
STEVE DAVIS: Investigations advise me that all of that is part of the ongoing investigation and they do not want to make any comments about that right now.
JEFFREY KAYE: Four funerals were held today for three of the murdered students and for Dave Sanders, a teacher and basketball coach.
STUDENT: He saved all of our lives in the cafeteria. He was running around, and I remember seeing him jump over the chairs and yelling at everybody to get down. And I truly believe that he saved my life with many, many other people.
JEFFREY KAYE: As a grieving community continues to pay somber tribute to the victims at makeshift memorials outside Columbine High School, today students from neighboring schools held an exuberant march to show sympathy for the victims.
