An Oregon teen accused of planning an assault on his high school wrote detailed plans to "shoot and throw bombs throughout the school", then kill himself before responding police officers could engage with him, according to court documents released today.
Police said the plans were written in notebooks that were found hidden beneath the floorboards in the teen's bedroom, along with two pipe bombs, two Molotov cocktails and at least two bombs made with a chemical drain cleaner.
Grant Acord, 17, made his first court appearance by video transmission today, but did not enter a plea on charges that include attempted aggravated murder and six counts each of unlawful possession and manufacture of a destructive device. He is being charged as an adult.
Wearing a light-gray sweatshirt and sweatpants with shaggy brown hair covering most of his forehead, Acord said little, but replied "yes, your honour" to questions from Judge Matthew Donohue, who set bail at US$2 million (NZ$2.4m).
Acord's writings included "multiple versions of the plans and diagrams to commit an attack" on West Albany High School, according to a probable cause affidavit signed by Albany Police Detective Mike Wood.
In one, labelled "The (Loosely Stated) 'Plan' AKA Worst case Scenario", the teen lays out an itinerary for an attack: Leave home at 7.30am, go to first period then retreat to the parking lot to prepare.
At about 11.10am, he would begin blasting music from the car while walking toward the school, a napalm firebomb in one hand and a duffel bag in the other.
"Drop duffel. Light and throw napalm, unzip bag and begin firing," the notebook said.
"Cooly state: 'the Russian grim reaper is here'."
The line is apparently a reference to the 2003 film Bad Boys II.
The plan went on: "Throw a smoke bomb prior to walking in. Proceed to enter the school, then shoot and throw bombs throughout the school. Kill myself before S.W.A.T. engages me.''
The detective wrote that the notebooks indicate that Acord ''compares himself to both Eric Harris and Dylan Klebold'', the teenagers who killed 13 people at Columbine High School in Colorado in 1999 before turning their guns on themselves.
Police said they found printouts of a website listing the weapons used by the shooters at Columbine High School and a list of items to use in an attack.
Prosecutor Chris Stringer declined to say whether police found firearms in the home.
On Monday, Acord's mother, Marianne Fox, issued a statement through a Corvallis lawyer, Alan Lanker, saying the teenager struggled with a rare form of obsessive-compulsive disorder.
''I grieve for my son, but understand and support the efforts of law enforcement to keep our beloved community safe,'' the statement said.
''This is a challenging and confusing time for everyone who knows Grant.''
Stringer, the prosecutor, declined to comment Tuesday about Acord's mother's statement.
No bombs were found during searches of the school, and classes resumed as scheduled on Tuesday.
