GREEN BAY ? Two 17-year-olds suspected of plotting a shooting spree at their Green Bay school were fascinated with the mass killings at Columbine High School and had homemade bombs and weapons at their homes, investigators said Friday.

The boys were arrested Thursday at East High School after a student went to an associate principal. A detective said Friday that one boy wanted to enact the plan Thursday but the other talked him out of it.

“If someone hadn’t come forward, we’d be talking about funerals instead of charges,” said Brown County Dist. Atty. John Zakowski.

William C. Cornell and Shawn R. Sturtz were arrested for suspicion of conspiracy to commit first-degree intentional homicide and conspiracy to commit arson. Zakowski said he planned to file charges next week.

Court Commissioner Jane Sequin ordered each teen jailed on $500,000 bond Friday. Police Detective Tom Molitor testified that both teens, who are seniors, told police they had been plotting the massacre for several years.
