The mystery still remains surrounding a Mercedes Benz stolen in 1992 found that was found by landscapers buried in an Atherton backyard.
Since the discovery Thursday morning, investigators have deployed cadaver dogs, dug out the vehicle by hand and used high-tech ground penetrating radar to see if there was any sign of human remains or foul play.
Investigators were able to determine the Mercedes Benz was reported as stolen to the Palo Alto police in September 1992. The possible owner of the vehicle is believed to be deceased. "We are waiting for DMV records that are being retrieved in the DMV archives," police officials said in the news release.
But the activity and large law enforcement presence has drawn the attention of neighbors in the affluent town located in the northern edge of the Silicon Valley.
