3 people, including gunman, hospitalized after shooting at Yorba Linda park, OC sheriff says

YORBA LINDA, Calif. (KABC) -- A dispute in a Santa Ana Canyon wilderness park ended in gunfire Sunday afternoon. Police said a man tried to run over someone with his car before turning a gun on two people and then himself.

The two victims and the suspect were all taken to the hospital. Further information about their conditions was not immediately available.

It all unfolded at Featherly Regional Park in Santa Ana Canyon. It's normally a mostly private RV park.

However, hundreds of people were gathered at the park in Yorba Linda, including countless kids, when the shots rang out Sunday afternoon.

"Ropes courses, actually, a birthday party was going on for a 9-year-old girl. There were probably 30, 25 kids there on the ropes course at the time, and all of a sudden it was, 'Hit the Ground. Get down. Everyone get down,'" witness Andra Montano said.

The park, which has a camping and RV section, was also host to a vintage Volkswagen event this weekend, where VW enthusiasts showed off their vintage vehicles.

The Orange County Sheriff's Department said the gunman and victims all knew each other and apparently got into an argument earlier in the day, but the suspect left the park.

"The suspect was involved with an altercation with one of the members, the victims, earlier in the day, responded back to the park, attempted to strike one of the victims with his vehicle, and then got out of the car and fired several times, striking at least two of the victims," Sgt. Gerard McCann said.

Deputies said the suspect then turned the gun on himself. All three gunshot victims were rushed to the hospital.

A fourth person was hit by the truck, but the injuries weren't serious, deputies said.

The sheriff's department did not immediately identify the suspect or the victims.
