Two people were found dead in an Orange County home early Sunday and the deaths were being investigated as a possible homicide, officials said.
The deaths were reported about 2 a.m. in the 32000 block of Peppertree Bend in San Juan Capistrano, OC Sheriff's Lt. Jeff Hallock said.
One man and one woman were found dead, and an 8-year-old boy believed to be the couple's son was hospitalized in serious condition, officials said.
Officials on Sunday searched the 9,000-square-foot mansion, which sits atop a hill and is protected by a security fence, gates and dogs. The neighborhood has been featured on Bravo's "The Real Housewives of Orange County."
Residents were surprised to hear of the deaths.
"They're always there, they're always together, that family never separates," friend of the victims Kelsey Winterbottom told NBC4. "The kids are with the parents every day, every minute. They do everything together. They're just the best family."
Neighbors said the couple has five children, including the hospitalized 8-year-old boy and two who may be away at college. It was not clear where the other two children were at the time of the deaths.
"It just scares me that they can get past that and makes me want to up our security," neighbor Sophie Waring said. "It's just sad that we're not even safe in our own homes."
Neighbors just want clues as to how the deaths may have happened.
"We live right next door and knowing that no one has been caught ... I feel like anyone could be in my backyard," neighbor Bria Peterson said.
Deputies said the deaths were not a result of a home invasion or robbery, but may have been a homicide.
"We don't have any specific suspect information at this point, but I'd like to reiterate that we believe San Juan Capistrano has been and continues to be a very safe community."
The names of the victims were not released pending notification of family members.
