Four people have died at a California food festival shooting, including a suspected gunman, police chief Scot Smithee told a news conference late on Sunday.
Fifteen more were injured, including some who suffered gunshot wounds, although the number of those shot was not immediately clear.
"It's just incredibly sad and disheartening that at an event that does so much good the community had to suffer from a tragedy like this," said Smithee, chief of police in the city of Gilroy, near San Jose.
The gunman appeared to have cut through a fence to get into the annual Garlic Festival. He may have had one accomplice, Smithee added.
Evenny Reyes, 13, told the San Jose Mercury News that at first she thought the gunfire was fireworks. But then she saw someone with a wounded leg.
“We were just leaving and we saw a guy with a bandana wrapped around his leg because he got shot,” Reyes told the newspaper. “There was a little kid hurt on the ground. People were throwing tables and cutting fences to get out.”
Another witness, Maximo Rocha, a volunteer with the Gilroy Browns youth football team, said he saw many people on the ground, but could not be sure how many may have been shot and how many were trying to protect themselves.
He told NBC Bay Area that “quite a few” were injured, “because I helped a few.”
One video posted on Twitter showed a blood-spattered woman sitting in the back of a semi-trailer and telling a man she had been shot in the hand.
Stage hand Shawn Viaggi told the Mercury News he heard gunshots and saw bullets hitting the ground. “I called out, ‘It’s a real gun, let’s get out of here,’ and we hid under the stage,” Viaggi told the newspaper, adding that he saw police officers trying to resuscitate one man.
Founded in 1979, the Gilroy Garlic Festival features food, drink, live entertainment and cooking competitions. It says it is hosted by volunteers and describes itself as the world’s greatest summer food festival.
It was being held at the outdoor Christmas Hill Park, where weapons of any kind are prohibited, according to the event’s website.
To provide a safe, family-friendly atmosphere, it said, entry was refused to anyone wearing clothing or paraphernalia indicating membership in a gang, including a motorcycle club.
Festival officials did not immediately respond to requests for comment.
Gilroy is about 30 miles (48 km) southeast of San Jose.
