Authorities said a man hit someone with a car at the Canyon RV Park in Anaheim on Sunday, fired at them and sent the gun to himself.
Three people, including the gunman, were taken to a hospital with gunshot wounds, and their condition is still unclear.
The fourth victim suffered minor injuries and remained at the scene.
“This is not considered a terrorist attack, but an isolated incident between people who know each other,” said Gerard McCann, a public information officer for the Orange County Sheriff.
McCann said in a video posted on social media platform X that the suspect appears to have had an argument with people in the recreational vehicle park, turned left and then returned with his car and gun to attack them.
The park was hosting a four-day event for Volkswagen enthusiasts at the time of the shooting, called the “Air-Cooled Carnival Gras Gras Picnic Weekend.”
Andrea Montano told KTLA-TV that she has been attending events with her family for years and has never seen anything that happened on Sunday.
