OAKLAND — The revealed secrets and named names, with one notable exception.

At the center of many crimes of corruption allegedly perpetrated by Oakland’s recent mayor is “Co-Conspirator 1.” The are David and Andy Duong, the father-and-son team behind a company called California Waste Solutions, as well as ex-mayor Sheng Thao and her longtime partner, Andre Jones.

The unnamed co-conspirator acted as a catalyst for alleged bribery schemes, including a pay-to-play arrangement that helped Thao win election in the first place, according to prosecutors.

But the person’s identity may not be such a mystery; the allegations spelled out conform with much of what is known about Mario Juarez, a longtime Oakland politician and behind-the-scenes consultant who has said he got into business with Andy Duong because of his longtime dream to house the homeless.

A two-time failed City Council candidate, Juarez was long thought to be cooperating with the federal investigators. Last June, just 11 days before the FBI raided Thao, the Duongs, and Jones in a pre-planned operation, Juarez survived an attempt on his life when gunmen showed up, .

Juarez was not injured by the men who fired at him, prompting him to return fire with his own legally-owned pistol, but the disturbing incident prompted authorities to rush the June raids, according to multiple sources with firsthand knowledge of the investigation.
