Kings County sheriff's detectives say 32-year-old Ramiro Trevino Jr. died after fatally shooting 31-year-old Johnathan Diaz and critically wounding 58-year-old Ramiro Trevino Sr. Saturday in Hanford.

Authorities say Diaz was a Lemoore police officer and a friend of Trevino Jr., who worked as a Kings County welfare fraud investigator.

Investigators say the shooting occurred around 9 p.m. at the party for the elder Trevino in the community about 33 miles (53 kilometers) south of Fresno.

Detectives say the two men intervened in a fight between Trevino Jr. and his girlfriend and soon after he armed himself with more than one gun.
