SEARSPORT – The local man charged with having a bomb factory also reportedly had writings about blowing up a high school and killing the principal.

Police said Monday that the writings were stored on computer disks owned by Irving Williams, 20, of the Bowen Road Extension.

Williams was arrested on explosive and drug charges early Sunday after homemade bombs and other items were uncovered during a search of the mobile home where he was staying.

Williams has been charged with criminal use of explosives, cultivation of marijuana and possession of drug paraphernalia. He is being held at the Waldo County Jail on $20,000 cash bail and is expected to make an appearance today in 6th District Court in Belfast.

Patrolman Steve Hegstrom said 20 computer disks were found among the explosive devices and bomb-making materials that were removed from Williams’ bedroom over the weekend. Hegstrom said he and Officer Michael Larrivee were in the process of reading the material stored on the disk when they came across stories dealing with blowing up a high school, murder and mayhem.

“It’s pretty chilling stuff,” Hegstrom said Monday.

With graphic descriptions of blood and brains reminiscent of the April 1999 shootings at Columbine High School in Littleton, Colo., one of the stories centers on a group of bombers dressed in black trench coats who take over the school during an assembly.

Besides killing the principal, the bombers shoot a number of students and detonate explosives throughout the school. At the conclusion of the story, one of the bombers blows himself up and another shoots himself in the head.

During the Columbine High School incident, two armed students wearing trench coats shot and killed 15 people.

Hegstrom said Williams told him the writings were fiction and did not mean any harm. Williams has “been very cooperative,” he said, since authorities discovered the explosive materials in his bedroom. The suspect helped identify some of the explosives and chemicals for the federal Bureau of Alcohol, Tobacco and Firearms agent who was called in on the case and has admitted testing some of his homemade bombs in the woods of Searsport.

Police found the cache of explosives while searching for Philip Millette, 23, of Searsport, a fugitive from justice. Tiffany Warman had called police Saturday to ask that Millette be removed from her Bowen Road Extension home. Because there was an outstanding warrant on Millette, Patrolman Hegstrom asked that Waldo County deputy sheriffs lend assistance.

When the officers were unable to locate Millette, they asked Williams, who lived with Warman and her husband, Jeremy Warman, if they could search the house to make sure he was not hiding within. Williams assented and when Hegstrom and the deputies found marijuana in the residence, they decided to conduct a more detailed search. That was when they located the explosives and other material. Millette remains at large.

Besides gunpowder and home-made bombs, the officers found various electrical switches suitable for making car bombs, time bombs and incendiary devices. Williams also had a number of notebooks filled with bomb-making instructions and diagrams.

Hegstrom said police have obtained information that connects other individuals to Williams’s activities. He said the entire case would be brought before the Waldo County grand jury at a later date.

A member of the state police bomb squad assisted in the removal of the items from the Warmans’ trailer. A state fire marshal took possession of all the explosive and flammable items. The evidence remaining was enough to fill an entire cabinet at the Searsport Police Department.

“I’m still going through the computer disks, and we still haven’t finished inventorying all of all this stuff,” Officer Larrivee said Tuesday.
