EVERETT, Wash. -- Everett police arrested a student at ACES High School for attempted murder after a journal detailing a planned school shooting was discovered by the teen's grandmother.

On Tuesday, the suspect's grandmother called 911 to report what she believed was upcoming and credible threats by her 18-year-old grandson to shoot students at ACES High School.  She showed officers excerpts from the journal and told them her grandson kept a rifle in a guitar case.

Authorities say the journal described shooting students and using homemade explosive devices at the school on Holly Drive.
