An elderly couple on Wednesday was found dead of gunshot wounds in a Novato home, the Marin County Sheriff's Office said.
Officers responded to a residence on the 600 block of Bugia Lane around 8:30 a.m. after family members called 911.
The death of the man and woman, who are believed to be in their mid-70s, is an isolated incident, sheriff's officials say. There is no threat to the neighborhood.
An investigation is ongoing and could last several hours. Sheriff's deputies said they are awaiting a search warrant so they can reenter the house and comb through it.
There is no confirmation yet on whether the pair's deaths were a murder-suicide.
