Gilroy shooter's motive may never be known as investigation finds few clues
Five days into the investigation of the Gilroy Garlic Festival shooter, authorities say they still aren't sure why he launched the attack that killed three and injured 13.
They have gathered evidence in Gilroy, Calif., and Nevada and tried to understand his digital footprint. But they admitted they may never know why he acted.
