A former student of Timberview Middle School in Colorado Springs was arrested after allegedly planning a mass shooting at the school, according to arrest records obtained Thursday by The Gazette. 

William Whitworth was arrested by members of the Elbert County Sheriff’s Office on March 31 on suspicion of attempted first-degree murder, and other charges, the affidavit states. Students were not at Academy School District 20 schools last week during the district’s weeklong spring break.

Investigators found instructions on how to build homemade bombs and a whiteboard with the floor plan to Timberview Middle School in the bedroom of a former student accused of planning a mass shooting at the Colorado Springs school, according to arrest records.
