Sebastian Villaseñor, 18, is a student at Ontario Christian High School in California. He was arrested last Saturday after complaints from another student about the alleged plan.

Authorities found seven rifles, two revolvers, a pistol and a shotgun in his home. The police also found 1,000 bullets in the house and said he confessed that he had a list of five students he wanted to attack. The detainee faces five counts of attempted murder and one count of attempted criminal threats.
