The Gilroy Garlic Festival draws tens of thousands each year, and like many large events, there are security checks at the entrance.
Gilroy Police Chief Scott Smithee said the gunman used “some sort of tool” to cut a fence next to a creek to get into the event.
Christmas Hill Park backs up against a wilderness area, though it is unclear exactly where the gunman entered.
Smithee said the festival had security checkpoints with metal detectors.
