Four dead in garlic festival mass shooting

A gunman opened fire at Gilroy, California's garlic festival Sunday, killing three before being shot dead by police. At least fifteen more were injured and a 6-year-old boy was among the dead.

There was "a white man in his early to mid-30s firing a rifle," eyewitness Julissa Contreras told NBC.

It was the 246th mass shooting in the US this year, according to US tracking website Gun Violence Archive.

The suspect entered the festival after cutting through a perimeter fence, Gilroy Chief of Police Scot Smithee told reporters. He said witnesses reported that a second suspect may have been involved, possibly in a support role.

Another eyewitness: "I could see him shooting in just every direction. He wasn't aiming at anyone specifically. It was just left to right, right to left. He definitely was prepared for what he was doing."
