An Oregon teen accused of plotting to attack his classmates planned to blare music before entering the school with a napalm firebomb in his hand and open fire while saying, "The Russian grim reaper is here," according to an affidavit.
After he threw the napalm firebomb, 17-year-old Grant Acord planned to unzip his duffle bag and begin firing on his classmates at West Albany High School, according to handwritten plans authorities said were seized from Acord's home.
Next, Acord plann called for him to "cooly state, 'the Russian grim reaper is here,'" according to the documents, which were released today.
The high school junior is being charged as an adult and made his first appearance in Benton County Circuit Court this afternoon via a video link.
Acord faces charges including attempted aggravated murder, manufacture and possession of a destructive device and possession of a deadly weapon with intent to use against another person. He was charged as an adult.
A judge ordered Acord to be held on $2 million bail.
He did not enter a plea and his court appointed attorney asked that a plea not be entered at this time.
Benton County District Attorney John Haroldson said the teen had a detailed plan, timeline and a deadly cache of weapons "specifically modeled after the Columbine shootings," that killed 13 people and injured 21 more in 1999.
Authorities said they found six homemade explosive devices -- including pipe bombs, Molotov cocktails and Draino bombs -- hidden in a compartment beneath Acord's bedroom floor.
He meticulously planned the massacre and kept a checklist of his current stock and items he needed to buy and their costs, and how he planned to use them, according to the documents.
"Proceed to enter the school, then shoot and throw bombs throughout the school," Acord wrote in his journal, according to the affidavit. "Kill myself before S.W.A.T. engages me."
Acord's mother, Marianne Fox, attended the court hearing today and released a statement to ABC News' Portland affiliate KATU-TV through her attorney, Alan Lanker.
"My heart goes out to everyone affected by Grant's struggle with PANDAS, 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," she said. "This is a challenging and confusing time for everyone who knows Grant. I will have no further comment while I wait with the rest of you to see what unfolds."
