HANFORD, Cali. – A fight between a man and his girlfriend turned into a bloodbath this weekend… and by the time it was over, two people were dead, including a police officer. 

The Kings County Sheriff’s Office released a statement confirming that 32-year-old Ramiro Trevino Jr., a welfare fraud investigator for the state of California, became enraged after getting into a fight with his girlfriend at their home in Hanford while hosting a birthday party for Trevino’s father.

As the argument began to get more heated, Trevino Jr.’s father Ramiro Trevino Sr. and friend Officer Jonathan Diaz attempted to intervene and calm the man down. 

Diaz served as a police officer in the town of Lemoore, and was off-duty at the time. Fox News reported that as the two men tried to get the girlfriend out of the home and away from the threat of violence, Trevino Jr. produced a weapon and fired at them, striking the two men multiple times. 

“It appeared the two victims were really trying to stop what was occurring,” Kings County Sheriff Dave Robinson said during a press briefing. 

It was their willingness to intervene and prevent a woman from getting hurt that put them in danger, police said.

“They definitely put their lives on the line to try to defuse the situation,” Robinson said.

The gunfire tragically took the life of Officer Diaz and critically wounded Trevino Sr.

After Trevino Jr. shot the two men, investigators say that he turned the weapon on himself and took his own life with a self-inflicted gunshot wound.

Neighbors reportedly thought that the gunshots were actually fireworks being set off, as they knew a party was being thrown for Trevino Sr. at the Hanford home. 

“I heard three shots, but I didn’t know they were shots at the time,”Julio Arevalo said to KFSN News after the incident.

But when he saw what was going on, he was shocked.

“I stepped outside, I looked and that’s when I saw a body on the floor, and I was like, ‘What just happened?'” Arevalo said. 

Investigators from the Kings County Sheriff’s Office confirmed that Officer Diaz died at the scene and that Trevino Sr. had to be rushed from his own birthday party to the emergency room, where he is fighting for his life, currently listed in critical condition. 

Police recovered three firearms from the scene, including a rifle and two handguns. 

“Based on evidence at the scene it does appear that the rifle was fired at least once and at least one of the handguns was fired,” Robinson said.

 

Hanford is located approximately 30 miles south of Fresno. 

Officer Diaz was off-duty at the time. He was reportedly the recipient of the public safety officer of the year award in Lemoore. He leaves behind two children.

Diaz previously worked for the Huron Police Department. They issued a public statement following the announcement of his death. 

“Huron Police Department is saddened by the death of our former Huron Police Officer Jonathan Diaz, and City of Lemoore Police Officer, at the time of his death. We extend our sincere condolences to the family of Officer Jonathan Diaz, Lemoore Police Department, and those who knew and worked alongside Jonathan,” the department said on Facebook.
