The two teenage gunmen who killed 13 people in a shooting spree at their high school before killing themselves also planted 30 pipe bombs as part of a plan to maim and kill as many people as possible, authorities in Littleton, Colo., said Wednesday. While police said they believed that Eric Harris, who just turned 18, and Dylan Klebold, 17, were alone when they walked into Columbine High School Tuesday and shot at students and teachers, the elaborate nature of their plan prompted suspicion that others may have known about it. “There was a lot of planning put into this. It took a considerable amount of time to make it (the arsenal),” said Jefferson County Sheriff John Stone. “I have concerns whether two people could carry all that stuff in there.”

  • The arsenal discovered by police was daunting: one sawed-off shotgun, one nine millimeter semi-automatic rifle and a handgun in addition to 30 pipe bombs planted at the school, in two cars in the school parking lot and at the assailants’ homes.
  • The death toll in the worst act of violence ever at an American school stood at 15 Wednesday, including the two gunmen who took their own lives. Officials will release the names of the victims on Thursday. Some of the victims’ bodies were found under desks and cubicles, indicating they may have been trying to hide. Abandoned backpacks remained on classroom desks Thursday, and the school is expected to remain closed for the rest of the year.
  • Students on Wednesday decorated with flowers a car belonging to Rachel Scott, who died in the attack. Teachers at the school are being hailed as heroes for their roles in calming and protecting students and possibly saving many lives.
  • Snow started to fall in Littleton on Thursday, bringing a hush to a shell-shocked community.
