The father of a six-year-old boy killed at the Gilroy Garlic Festival has described the shock and despair he felt after losing his son, saying the boy had his "whole life to live."
Alberto Romero told the San Jose Mercury News he was at home with his nine-year-old daughter when his wife phoned him to relay the devastating news that she had been shot, along with their son and her mother.
"I couldn't believe what was happening, that what she was saying was a lie, that maybe I was dreaming," the 33-year-old electrician said, in a video where he appears visibly distressed.
He went straight to St Louise hospital in Gilroy to see his son, who was in a critical condition.
"They told me he was in a critical condition and they were working on him. Five minutes later they told me that he was dead," Mr Romero said.
"There's nothing I really can do besides try to be with him until I can put him in his resting spot, wherever that is," his father, Alberto Romero, told NBC Bay Area.
"My son had his whole life to live and he was only 6. That's all I can say."
The young boy was one of three victims at the festival, where 15 others were injured and the gunman was shot dead by police. His other grandmother, Maribel Romero, who was not at the festival, described him as "a really loving boy."
"I want justice for my grandson," she said. A picture of Steven wearing a t-shirt that says "the birthday dude" was shared online by leaders calling for an end to gun violence.
2016 presidential candidate Hillary Clinton retweeted a comment from his father, Mr Romero and said "America cannot go on like this. For the sake of our kids, we have to change."
“My son had his whole life to live and he was only six,” said Alberto Romero. His son, Steven, was one of three people killed in yesterday’s shooting at a garlic festival in Gilroy, California.
The gunman was shot dead by police officers within minutes of opening fire early on Sunday evening at the three-day Gilroy Garlic Festival, about 48km southeast of the city of San Jose.
He has been named by local media as 19-year-old man, Santino William Legan.
A second suspect "was involved in some way, we just don't know in what way," Gilroy Police Chief Scot Smithee said, without giving further details. "We have no idea of a motive," he said.
Police recovered a rifle at the scene, Smithee said.
Police said the gunman cut through a fence to evade metal detectors and other security at the festival's entrance, police said.
Festival workers Cheryl Low and Candice Marquez told CBS both their bosses had been shot and are in hospital in a stable condition. They said the gunman opened fire randomly on the crowd.
"No, no. Just anybody. He was going back and forth," Ms Marquez said.
"It was random," said Low. "He shot one shot, then he put the clip in, and he just started moving shooting back and forth, walking towards our tent because that's where most of the people were in that area, and he started just shooting."
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. Founded in 1979, the Gilroy Garlic Festival is an annual event run by volunteers and held outdoors at Christmas Hill Park.
Weapons of any kind are prohibited, according to the event's website, which also said anyone wearing clothing or paraphernalia indicating membership in a gang, including a motorcycle club, would be refused entry.
"I want to express my extreme shock and sadness about what's happened today," said Gilroy Mayor Roland Velasco, who described the attack as a "tragic and senseless crime."
