FALLBROOK, Calif. — Authorities on Friday are investigating a shooting that left one dead and two wounded at a plant nursery in the Fallbrook area, first responders said.

The gunfire occurred around 2:44 p.m. at Atkins Nursery at 3100 Reche Road, the San Diego County Sheriff’s Department said.

When deputies arrived on scene, they found three people with gunshot wounds, according to authorities. One man in his 50s was confirmed dead while the other two victims, a woman in her 30s and a man in his 70s, were taken to a local hospital, where they are expected to survive. All of the victims are believed to be employees of the nursery.

The identity of the deceased victim is known, but authorities are not releasing that information until the person’s family has been notified.

A 76-year-old male shooting suspect, who was a father of one of the victims and worked at the property, was taken into custody without incident during a search of the nursery, the sheriff’s department said. That suspect has been identified by authorities as 76-year-old Enrique Barajas Gutierrez.

There were several people on the property during the shooting, which investigators are trying to determine if they were owners, residents or other employees.

“We do know that the suspect is a father of the female victim. We do not know the relationship between the suspect and the other victims,” said Lt. Chris Steffen with the sheriff’s department.

The sheriff’s department says the weapon used is believed to be a rifle of some kind – though it hadn’t been found as of Friday evening on the several-acre property.

About 10-15 witnesses are being interviewed in the case, and identities of the victims and suspect will be release at a later time, according to authorities.

There is no further threat to the public, but authorities advise Reche Road is currently closed from Old Highway 395 and Gird Road due to the investigation.

California Governor Gavin Newsom’s office also commented on Friday’s shooting.

“We are monitoring the shooting in San Diego and coordinating closely with local officials on this developing situation. Our thoughts are with those impacted by today’s act of violence, and all the Californians recovering from tragic shootings this year.”

After processing, the sheriff’s department said Gutierrez will be booked into the Vista Detention Facility on murder charges.
