Deputies responded to the 32000 block of Peppertree Bend regarding a call of "unknown trouble" around 1:52 a.m.
"We can't specify at this time what was said by the caller, however the call was titled as 'unknown trouble,' that's what the deputies responded to," said Lt. Jeff Hallock with the Orange County Sheriff's Department.
The boy was transported to Mission Hospital in serious condition. Authorities say the boy will survive his injuries, but they did not specify what those injuries are.
Friends and neighbors have identified the couple as Brad and Andra Sachs. They say they lived in the home with their 8-year-old son and two teenage daughters. Friends say the couple's two older sons are away at college.
Neighbors say they did not hear any gunshots or anything unusual from the 10,000 square-foot, multi-million-dollar home. Investigators will not say who was in the home at the time, or how the man and woman were killed. Investigators say it does not appear to be a murder-suicide, and they do not know what the motive may have been or who a suspect could be.
People who knew the couple are devastated.
"They were the most genuine people. They were beautiful, such amazing people, I can't..." said neighbor Brittany Zkiba, who broke down crying.
But others say the Sachs had made quite a few enemies in their business dealings.
"Shocked, my stomach sank, and then I thought, 'I'm not surprised,'" said Ken Baum.
For the last two years, Ken Baum has rented office space at one of the properties the Sachs own. He says as soon as he signed the contract, things took a turn.
"Shady, underhanded, we don't like it, move, sue me, we don't care. And they also told us as soon we moved in, don't tell anybody we were here, don't tell anybody you know us, don't tell them our name, don't tell them this is our business next door to you, we don't want to be known," he said.
Neighbors say the Sachs' home was gated and a security code is needed to enter. Investigators will not say if there were any signs of forced entry.
Friends say they have no idea who would want to hurt the couple. Residents say they would often see the family taking walks throughout the neighborhood.
Authorities say given the size of the home, the investigation is expected to take hours to complete.
