Authorities in Southern California responding to a report of child abuse found two women and a teenage girl dead inside a home Monday in one of the nation's wealthiest communities.

San Diego County deputies answering the 911 call went to the home in Rancho Santa Fe at midday and spotted one woman's body through a window, sheriff's Lt. Kenn Nelson said.

The deputies went in and found the other bodies. All three had "obvious signs of trauma," Nelson said. He declined to say whether they were shot, stabbed or beaten.

Authorities didn't immediately label the case a murder-suicide but said they weren't searching for any suspects.

The identities of the women and the teenager were not immediately released. Nelson said investigators were trying to determine their relationship and motive for the deaths.

Rancho Santa Fe is an unincorporated county area about 25 miles north of San Diego, in the mountains east of Pacific beach communities. The home is near a country club and the center of the community, which is known for its palatial homes, sprawling lawns and horse pastures.
