A former Santa Ana police officer who worked as an unlicensed private investigator was charged Friday with 63 counts, ranging from defrauding clients to intimidating witnesses to posting ads on Craigslist seeking women to engage in sex acts with his Labrador retriever.

Kevin Michael Sianez, 53, of Fountain Valley is also charged with illegally operating a private investigation service without a license, according to the Orange County district attorney’s office.

Sianez opened his office in 2005 and employed five people, most of whom were family members, the district attorney’s office said. He allegedly posted false reviews of his business on the Internet, misleading potential clients into believing his business had nationwide offices and investigators.

He also is accused of attempting to dissuade two former employees who tried to report his actions to the police, the district attorney’s office said.
