The deaths are being investigated as foul play, deputies said. The victims were members of the same family and all had been shot, the Orange County Register reported.
The bodies may have been inside the home for two to three weeks. The victims were described as an elderly woman, a man and a woman in their 40s, and two women in their early 20s.
Orange County Sheriff's deputies are not pursuing any suspects at this time, and say the community has no reason to be fearful.
