A 67-year-old female and a 68-year-old male were found around 5 p.m. inside the large Orange home located about 30 miles from downtown Los Angeles, according to CBSLA.
The victims were not immediately identified but longtime neighbors told reporters Gordon’s parents live in the house.
It was not immediately clear how the victims died but one investigator said they might be dealing with a murder-suicide. Gordon, a California native, boasts more than a dozen NASCAR series wins. He recently began racing in the Speed Energy Formula Off-Road series, which he founded in 2013.
