A self-proclaimed government watchdog could have his private investigator’s license revoked, depending on what a governing board could decide next month. Another private investigator filed an official complaint with the New Mexico Regulation and Licensing Department (RLD) last month against Carlos McMahon that alleged he obtained his private investigator license fraudulently and abused his position as an investigator. McMahon has been in and out of the news since he filed a whistleblower lawsuit against the Bernalillo County Metropolitan Detention Center, his former place of employment, in 2010. At that time his name was Carlos Villanueva. He changed his last name to McMahon this June.
