Police arrested an expelled 17-year-old student who allegedly plotted to blow up his former high school in Tampa on the first day of class.
Jared Michael Cano had allegedly amassed materials to make an explosive that he hoped would kill more people than the Columbine High School massacre, according to The Tampa Tribune.
A raid Tuesday evening by police uncovered Cano's journal, which had schematic drawings of the school and passages about his deadly plans, according to TV station WTSP. Tampa police said in a statement his diary contained "a minute-by-minute plan of carrying out the violence."
Authorities were tipped off Tuesday about the former student's looming attack on his old school, according to news reports. Their search of his home turned up shrapnel, fuel, plastic tubing and timing devices for a pipe bomb.
Besides the violent scheme he allegedly undertook, Cano was busted for growing marijuana. The Associated Press said.
The list of felony charges against Cano includes possessing bomb-making materials, cultivating marijuana, drug paraphernalia possession, marijuana possession and threatening to detonate a destructive device, The St. Petersburg Times said. Authorities might charge Cano as an adult, WTSP said.
He's been arrested before for burglary, carrying a concealed weapon and marijuana possession, but the cases were dismissed or never pursued, The St Petersburg Times said.
Fifteen died in the 1999 shooting at Columbine High School in Colorado.
