CLEVELAND (AP) — A man pleaded not guilty Thursday to a 41-count indictment charging him with plotting with an Indiana teenager to carry out Columbine-style attacks at two high schools in Indiana and Ohio.

An attorney for Lee Billi, 33, of suburban Lakewood, entered the plea by video hookup from jail. Billi is being held on a $250,000 bond.

Billi was indicted Tuesday on two counts of conspiracy to commit murder, 38 counts of pandering sexually oriented matter involving a minor and one count of possessing criminal tools.

Billi has been declared indigent and will be represented by a public defender. A message seeking comment was left Thursday at the public defender's office.

Authorities said Billi and a 16-year-old boy exchanged e-mails in April, discussing simultaneous mass murders at the teen's high school near South Bend, Ind., and at another location that police haven't identified.

A computer was removed from Billi's home along with computer disks, papers, books and three partial boxes of handgun ammunition, authorities said.

Prosecutors found child pornography that had been downloaded onto Billi's computer and saved onto computer disks, said Cuyahoga County prosecutor's spokesman Ryan Miday. Miday also said Billi had looked up dates of gun shows where he could buy guns several days before his April arrest.

The teen has been charged in Indiana with a juvenile count of conspiracy to commit murder. Court documents filed by prosecutors say he had picked a date for the attack at his school and researched the "Anarchist's Cookbook," buying a 9 mm handgun and making propane bombs.

Police have said they don't know how far along the two were in the alleged plan, but they had talked about a Columbine-style plot, a reference to the 1999 massacre at a Colorado high school in which two students killed 12 classmates and a teacher and then committed suicide.

Authorities said they found more than 100 knives and several illegal snakes at the teen's home in South Bend.
