GARDEN GROVE, Calif.—A 25-year-old man is suspected of fatally stabbing a man and injuring a teenage girl at a home in Garden Grove, police said March 27.

The suspect, Juan Carlos Fernandez Bustos of Garden Grove, was hospitalized Monday for injuries sustained in a fracas Sunday night at a Garden Grove home, Garden Grove police Sgt. Nick Jensen said.

Police were dispatched just before 10:30 p.m. Sunday to the 10300 block of Lampson Avenue.

Bustos, who previously dated someone living at the residence, got into an argument with family members that escalated into a physical conflict, Jensen said.

A 43-year-old man, whose name was not immediately released, intervened to stop the struggle and got stabbed in the upper body, Jensen said. He was rushed to an area hospital, where he was later pronounced dead.

A 16-year-old girl who also attempted to quell the conflict suffered a non-life-threatening injury to her hand, Jensen said.

The family identified the suspect, who was later tracked down at a nearby hospital, where he was being treated for injuries, Jensen said.
