An Oregon teen accused of planning an assault on his high school wrote detailed plans to “shoot and throw bombs throughout the school.”

Court documents released Tuesday include an excerpt of the plans police say they found after receiving a tip that 17-year-old Grant Acord planned to attack his high school in Albany. The writings were found along with two pipe bombs, two Molotov cocktails and at least two Drano bombs in a secret compartment beneath the floor in Acord’s bedroom.

According to the documents, Acord wrote of plans to begin his assault by lighting and throwing a napalm bomb, unzipping his bag and shooting.

Acord appeared in court Tuesday and did not enter a plea. A judge set bail at $2 million.

Acord was arrested Thursday night after police got a tip he was making a bomb to blow up his high school south of Portland.

On Saturday, District Attorney John Haroldson said Acord will be charged as an adult with attempted aggravated murder.

On Monday, Acord’s mother, Marianne Fox, issued a statement through a Corvallis lawyer, Alan Lanker, saying the teenager struggles with a rare form of obsessive-compulsive disorder.

The boy lives primarily with Fox, Lanker said, adding he represents the mother and isn’t the youth’s defense attorney.

Authorities didn’t immediately respond to requests for comment about the mother’s statement.

The Associated Press normally doesn’t name minors accused of crimes but is doing so in this case because of the seriousness of the allegations and because Acord is being charged as an adult.

Haroldson said the alleged plot was “forged and inspired” by the 1999 massacre at Columbine High School in Colorado. He said investigators found written plans, checklists and a diagram of the school, along with the six bombs.

Acord’s classmates say he discussed bomb-making in the weeks before his arrest, but did not speak of a plot to inflict damage.

No bombs were found during searches of the school, and classes resumed as scheduled Tuesday.
