A man and woman who were found dead in their San Juan Capistrano home over the weekend were both shot to death, authorities said Tuesday.
An 8-year-old boy who is believed to be their son was also shot and remains hospitalized.
Bradford Hans Sachs, 57, and Andra Resa Sachs, were found dead inside their home a little before 2 a.m. Saturday. Two teenage girls were also inside the home at the time of the shooting, authorities said.
The couple was divorced but lived together, said Orange County Sheriff's spokesman Jeff Hallock. People who knew them said they lived together with their children -- an 8-year-old boy and two teenage girls. Two older children lived on their own.
Their multimillion-dollar home in an upscale neighborhood is surrounded by a fence, and a tall metal gate blocks the driveway.
Investigators spent much of Saturday searching the home and the shrubs and bushes around it, but no suspects were immediately identified and no arrests have been made.
Investigators have said they are looking at the case as a homicide and are "exploring all possibilities."
Neighbor Patty Bonin described the couple as a nice family that often rode bikes around the neighborhood and took vacations together in an RV.
According to public records, the Sachses were landlords in San Juan Capistrano and owned multiple businesses.
Chris Knuth, owner of Star Motors in San Juan Capistrano, rented one of their offices in the city and said the couple was helpful and encouraging.
"They were always nice, courteous and helpful to us," he said. "They always seemed happy to see us grow."
Ken Baum, who also rented from the couple, told The Times on Tuesday the Saches seemed to be hiding from someone.
As soon as Baum signed his lease with the couple about two years ago, "They immediately told me, 'Make sure that nobody knows who we are, that you don't know us,' " he said.
The couple kept an office next door to Baum's business, Biodynamax, a sports training facility, but "they didn't want anybody to know that they were in that little office door … they always had it locked," he said.
Andra Sachs was difficult to work with, Baum said. But, he added, "I never thought anybody would try to kill her, my god … never in my wildest dreams did I think this might happen."
