Updated 2: 10 p.m.: San Mateo County Sheriff's Office is investigating a report of a possible vehicle that drove off a cliff in Montara.
At about 11:45 p.m. on April 25 a driver reported he saw an oncoming vehicle veer towards him before appearing to drive off the cliff.
Search efforts for a possible red vehicle began overnight with a formal search initiated at about 6:45 a.m. this morning, with the use of a plane from the Sheriff's Office and boats from the San Mateo County District Harbor Patrol, according to Sheriff's spokeswoman Rosemerry Blankswade.
"There are some small cuff marks on the road that indicate the vehicle may have gone off the cliff," Blankswade said.
At about 1 p.m. car parts and personal articles were found near Montara Beach, but none of the items had any identifiable information on them. The U.S. Coast Guard sent a helicopter and California State Parks also responded to assist in continued search efforts.
Traffic is flowing as normal, according to the Sheriff's Office.
No vehicle has been located at this time.
