Homicide detectives were investigating after a man was found stabbed to death inside a Diamond Bar home on Monday.
A man who lives with the victim in the residence on the 21000 block of Trigger Lane discovered the body just after 3 p.m. and called 911, according to Los Angeles County Sheriff’s Lt. Charles Calderaro.
Paramedics responded to the scene and found the victim suffering from multiple stab wounds to his upper torso. He was pronounced dead at the scene, Calderaro said.
Authorities have not yet identified the man, but Calderaro said he appeared to be Asian and in his late 60s.
Deputies who responded began canvassing the neighborhood for witnesses, but as of Monday evening none had been found, the lieutenant said.
The person who called 911 was middle-aged and not believed to be related to the victim, according to Calderaro.
When asked whether that person was involved, Calderaro replied, “We don’t believe that at this time, but we are investigating it further.”
It’s possible that one other individual lives in the home, the lieutenant said. Video from the scene also showed a small dog being loaded into a county vehicle.
So far, detectives have few leads on a suspect.
“We don’t know,” Calderaro said. “It could be a disagreement between two individuals. At this point, we’re just trying to find out as much information as we can.”
Investigators were working to speak with neighbors and to locate anyone who may have heard some commotion.
