A Lincoln Heights man was killed after apparently confronting an intruder in his apartment Monday night.

Authorities received a burglary in progress call in the 2000 block of North Griffin Avenue around 9:30 p.m., Los Angeles Police Department Lt. Ryan Rabbett said.

Arriving officers located a Hispanic man in his 60s down inside the apartment who was “suffering some type of assault or blunt force trauma,” Rabbett said.

Investigators believe the intruder entered the apartment and got involved in some type of assault or fight with the victim when he returned from watching fireworks.

The victim, who was identified by police as 64-year-old Jose Mancia, was pronounced dead at the scene by paramedics.

Investigators were still trying to determine what type of weapon was used in the attack.

The suspect, who was wearing a face mask and dark clothing, fled the apartment on foot, Rabbett said.

The victim’s brother believes Mancia may have been targeted but investigators have not announced a motive for the attack.

Police said the victim’s spouse and child were also around at the time of the incident but neither were physically harmed by the intruder
