Sheriff's deputies on Monday discovered the bodies of three females, two adults and one teen, in an upscale home in Rancho Santa Fe.
As they wrapped up their investigation on Tuesday morning, deputies were waiting on the San Diego County Medical Examiner's Office to rule on the official cause of death of the females.
Deputies responded to a 911 call from a friend of one of the victims about a possible child abuse case just before noon Monday.
Responding to the home in the 17100 block of Via De La Valle, they saw the body of one of the females through a kitchen window, said San Diego County sheriff's Lt. Kenn Nelson. The home is near the Rancho Santa Fe Golf Club.
After forcing entry, they found all three bodies in separate areas of the house, Nelson said. The females all had visible signs of trauma, though deputies will not disclose how they died.
The adult women were in their mid 40s and the third female was a teenager, deputies said.
Nelson said they do not believe there are any outstanding suspects in the case, indicating the situation is a murder-suicide.
Investigators are still trying to determine the relationship of the females and a motive.
The grisly deaths are not believed to be connected to the death investigation under way in Encinitas.
Via De Santa Fe to the south and Las Colinas to the north have been closed off as authorities work on scene.
