Bodies of man, woman found in driveway of home in San Anselmo

SAN ANSELMO, Calif. - Authorities are investigating the death of a 32-year-old man and a 30-year-old woman who were found lifeless in the driveway of a home in San Anselmo Friday morning.

Hazmat crews responded to the Sleepy Hollow neighborhood after the initial first responders reported a possible hazardous materials incident related to the death.

By Friday evening, the Marin County sheriff revealed in a press release that preliminary findings indicated the deaths may be related to illicit substance use. No evidence of foul play or suspicious circumstances were suspected.

The man was found on the ground next to a vehicle. The woman was found inside the vehicle, along with a dog.

Authorities haven't released the names of the two victims because they're still working to properly inform next-of-kin. However, authorities did reveal that the 32-year-old man resides in the Mill Valley area, and the 30-year-old woman is from Tiburon.

Neighbor Louise Franz said that the previous owners of the home had moved out and the home should have been vacant.

"It's a little frightening," Franz said. "I live right around the corner." 

The Marin County coroner will perform an autopsy early next week. They will also perform toxicology testing in order to better determine a cause of death.

Sheriff's say there is no threat to the community.
