Police: No remains in car buried behind Atherton mansion

The car was removed from the home by a tow truck and transported Saturday to the San Mateo County Crime Lab for further inspection and processing. On Sunday, ground penetrating radar was used to examine the scene, the department said.

"This examination did not reveal anything unusual or suspicious at the scene and no human remains were located," it said.

"This concluded our on-scene investigation," the department added.

Police have not said who owned the car, which was reported stolen in nearby Palo Alto in September 1992, or who might have buried it in the backyard of the sprawling mansion. Police said Monday they had no further comment.

Investigators believe the car was buried 4 to 5 feet (1.2 to 1.5 meters) deep in the home's backyard sometime in the 1990s — before the current owners bought the home.

Atherton police said the possible owner of the car is believed to be deceased but officials were waiting for DMV records to confirm that.

Authorities wouldn't say if investigators believe the vehicle was registered to Johnny Lew, who built the home and lived there with his family in the 1990s. Lew had a history of arrests for murder, attempted murder and insurance fraud,

KRON-TV reported Monday that the car has a personalized license plate that includes "Lew."

Lew died in Washington state in 2015, a year after the family sold the house, his daughter, Jacq Searle, told the San Francisco Chronicle.

Lew was arrested in the late 1990s for insurance fraud after he hired undercover police officers to take a $1.2 million yacht "out west of the Golden Gate Bridge into international waters and put it on the bottom," the newspaper reported.

In the 1960s, Lew was found guilty of murdering a 21-year-old woman in Los Angeles County. He was released from prison after the California Supreme Court reversed the conviction in 1968, citing hearsay evidence that should not have been allowed at trial. Records showed that in 1977 Lew was convicted of two counts of attempted murder, also in Los Angeles County, and spent three years in prison, the Chronicle reported, citing court records.
