The Marin County Sheriff's Office is investigating the deaths of a man and woman found in a driveway Friday morning.

The Ross Valley Fire Department responded to the incident in the area of West Oak Knoll Drive in Sleepy Hollow, an unincorporated area of Marin County just north of Fairfax and San Anselmo (see map above).

When officials arrived at 8 a.m., both of the victims were dead. One was in a car and the other outside a car, said Sgt. Brenton Schneider.

"Due to the circumstances surrounding the deaths of the individuals, we are waiting for the Marin County Hazardous Materials Team to respond to the scene to assist with our investigation," the sheriff's office said in a statement.

The reason for the hazardous-material situation can't be explained at this point, said Sgt. Schneider, but, "There is no threat to the community."

"We’ll be on scene for awhile investigating," he added.

This is a developing story. SFGATE will offer more details as they become available.
