Authorities in Orange County say four killings in a suburban home are a murder-suicide.

Sheriff's Lt. Jeff Hallock had already said no suspects were being sought after the bodies of two male and two female victims were discovered in the home in Mission Viejo on Tuesday morning.

But at a late-afternoon media briefing, Hallock said investigators had ruled that one of the victims had killed the other three before committing suicide.

The bodies remained in the home late in the day, and authorities had yet to release the names, relationships or causes of death of any of the victims.
