Police and
FBI officials said at a news conference two days after the rampage in the northern
California town of Gilroy that they still lacked any firm evidence about what spurred the suspect, Santino William Legan, 19, to launch his attack.
Legan was shot dead by
police moments after he began firing with an assault-style rifle into a crowd attending the annual Gilroy Garlic Festival, a decades-old event celebrating produce farmed in the countryside of California's Santa Clara Valley southeast of San Jose.
