Three felonies have been added to the drug charges a 30-year-old Door County inmate was already facing.  Michael Estevez is accused of trying to pay for a hit on a drug informant while he is still behind bars.  Estevez is charged with conspiracy to commit a homicide, solicitation of first-degree intentional homicide and conspiracy to intimidate a witness.  He was arrested by the Door-Kewaunee Drug Task Force in February on suspicion of selling drugs.  Another inmate told jailers Estevez had approached him about a “murder-for-hire.”  He wanted the informant to be killed by an overdose.
