Police knew of Columbine threats

The two students who gunned down 12 classmates and a teacher at Columbine High School bragged about making pipe bombs and said they were looking for a “ground zero” two years before the bloodbath — and authorities knew it, the sheriff said Wednesday.

AUTHORITIES HAVE said they knew about violent rants by Eric Harris and Dylan Klebold in 1998, a year before the shootings, and that a search warrant was not acted upon.
But Jefferson county Sheriff Ted Mink, who took office in July, said Wednesday that someone had called the sheriff’s office a year earlier, in 1997, to tip off authorities about a Web site run by Harris.
A deputy investigated the tip and forwarded a report and printouts from the Web site to a sheriff’s investigator in charge of computer-related crimes, Mink said.
The investigation of the Web site apparently stopped there, Mink said. The report was not found until last week, when a deputy came upon it as he was leafing through a training manual, the sheriff said.
