4 dead including one suspect, 15 injured in shooting at California food festival

A gunman shot and killed three people at a food festival in California Sunday evening.

According to police, a gunman began shooting festival-goers at the Gilroy Garlic Festival at about 5:41 p.m. local time. Officers immediately engaged the suspect, who was shot and killed by police.

Fifteen other people were injured.

Police are searching for a second suspect that may have been involved in the shooting. It's unclear if that person is armed.

"The hearts of Gilroy PD and entire community go out to the victims of today's shooting at the Garlic Festival," the tweet said. "If you are looking for a loved one, please go to the reunification center at Gavilan College at parking lot B."

Police responded to the scene around 5:30 p.m. local time (8:30 p.m. ET), according to The Mercury News .

Video from the festival appears to show people fleeing after hearing gunshots.

Lex De La Herran told CNN he was walking away from the stage and "about two minutes later, I looked over to hear multiple gun shots and saw smoke through the air."

"Initially I thought it was fireworks," he said. "People started screaming and running, I instinctively did the same. It was complete chaos."

De La Herran said a piece of shrapnel hit him in the head.

"I remember seeing a whole stampede of people running, jumping fences," he said. "Some man screamed 'Those are real!'"

Two patients are being treated at Stanford Medicine, spokeswoman Julie Greicius said.

The Santa Clara Sheriff's Department dispatch told CNN an emergency center for this incident has been established at W 6th St and Hanna street.

Gilroy police said a witness line and family reunification line had also been set up.

A law Enforcement official confirms FBI agents from the San Francisco division are responding. ATF San Francisco's field division is also assisting , according to a tweet from the agency.

'It's one of the scariest feelings'

Miquita Price told CNN there were hundreds of people at the festival Sunday.

"It was people just enjoying the day," she said.

When Price realized someone was shooting, she ran and then laid down on the ground. The shooter stopped and that's when she said she ran to a truck. Price said a woman running next to her was shot.

"It's one of the scariest feelings," Price said. "I think this is all like a nightmare. I don't believe this is reality right now."

Peter Winzell was at the festival near its main stage when he saw the shooter. He told CNN affiliate KPIX-TV the band was playing the last song when the shooting started. He said he heard 20 to 25 shots.

"I saw him for approximately one second, he was firing with intent to hit people," he said.

Thirteen-year-old Evenny Reyes of Gilroy told the Mercury News that she and her friends had spent the day at the festival.

"We were just leaving and we saw a guy with a bandana wrapped around his leg because he got shot. And there were people on the ground, crying," she told the newspaper. "There was a little kid hurt on the ground. People were throwing tables and cutting fences to get out."
