Gilroy Garlic Festival

The FBI is keeping a tight lip on what they’ve found on the shooter’s computer, phone, and thumb drives, but a law enforcement source describes discovering “extremist materials.”

While a motive has still not been discussed in Sunday's mass shooting at the Gilroy Garlic Festival, we know that the 19-year-old implicated spent the last months of his life in solitude in a sad-looking triplex near I-95 in Nevada.
