Authorities in Southern California were searching late Saturday for a gunman who shot three police officers who were trying to resolve a family dispute, killing two of them. 

“It was a simple family disturbance and he elected to open fire on a few of the guardians of the city,” Palm Springs Police Chief Bryan Reyes, his voice breaking, told reporters.

The chief, near tears, identified the slain officers as Jose “Gil” Gilbert Vega and Lesley Zerebny.

“Today Palm Springs lost two brave officers,” Reyes told reporters, his voice shaking with emotion. “I am awake in a nightmare right now.”

Police said Zerebny recently returned to the force from maternity leave after giving birth to a now-4-month-old daughter. Vega, the father of eight, was a 35-year veteran who planned to retire in December. The wounded officer’s name was not released.

Reyes said the three officers were standing near the front door speaking with the man, “trying to negotiate with the suspect to just comply,” when he suddenly shot them.

He said the shooter was not apprehended and may still be in the house. He said Riverside County sheriff’s SWAT officers had the residence surrounded and were now leading the investigation.

Reyes also urged the media and others not to stream live video of police officers’ movements on social media, adding it could put them in danger.

“Understand that we’re actively looking for a cop murderer,” he said.

Dozens of law enforcement officers converged on the normally quiet residential neighborhood in this desert resort city after the shooting. They sealed off several blocks and evacuated some residents.

Police Sgt. William Hutchinson said officers were warning people already inside their homes to stay there, lock their doors and not answer them until further notice.

Although Reyes didn’t identify the shooting suspect, he indicated police had had previous dealings with him.

A neighbor, Frances Serrano, told The Associated Press she called authorities after the father of the shooting suspect came to her house across the street and told her his son was “acting crazy.”

He said, “Help. I need help. My son is in the house, and he’s crazy. He has a gun. He’s ready to shoot all the police,” Serrano told the Los Angeles Times.

She’d gone back inside her home before officers arrived, Serrano said, and a few minutes after they got there she heard gunfire, “starting with a loud — I mean really loud — ‘bang!’” she told the Times. Moments later officers were knocking on her door, warning her to stay inside.

Serrano said the man police are looking for had been in jail at one time and had to wear a monitor on his ankle when he was first released. But she added that he had always been friendly and polite to her and her family.

“We never had any problems with him,” she said. Serrano also told the Times that she believed the man was in his mid-30s.

The shooting occurred just three days after a popular Los Angeles County sheriff’s sergeant was shot and killed in the high desert town of Lancaster.

Sgt. Steve Owen was answering a burglary call when sheriff’s officials say he was shot and wounded by a man who then stood over him and shot him four more times.

A paroled robber has been charged with murder.

Lancaster residents were organizing a candlelight memorial for Owen Saturday night.
