According to Newsroom Panama, a confidential informant for the US DEA (Drug Enforcement Agency) who was sent to Panama whilst in the agency’s witness protection program was killed, along with his son and wife, in 2007 by William “Wild Bill” Holbert. The informant, known as Mike Brown, was unlucky enough to have crossed paths with Holbert who was arrested in Panama last week under suspicion of a series of murder charges.
