VISTA, Calif. -- A son called police after discovering the bodies of his parents inside their home in Vista on Sunday, according to the San Diego County Sheriff's Department.
While investigators said they could not yet draw any conclusions, they believe murder-suicide "is a possibility."
The grisly discovery was made in the 800 block of Warmlands Avenue at about 1 p.m., Lt. Rich Williams said.
The unnamed son, a man in his 30s, told authorities he lived at home with his parents. Investigators received a warrant to search the home late Sunday evening and were trying to determine the moments leading up to the couple's death. Detectives said they were not actively looking for any outstanding suspects.
The son told deputies there was a gun in the house and at least one neighbor told authorities a gunshot was heard earlier in the day.
