It appears that the suspect behind Sunday’s deadly shooting in Gilroy, CA may have been planning an even larger attack.

Investigators searching the Nevada home of 19-year-old Santino William Legan say they found literature about both white supremacy and radical Islam, along with ammo boxes, a gas mask, a knife, and other materials pointing to an attack. The FBI is currently reviewing his computers and other electronic devices.

Legan was shot and killed by police after he opened fire at the Gilroy Garlice Festival on Sunday, killing three people and wounding more than a dozen more.
