Madison Heroin Dealer Gets 10 Years in Prison

MADISON, WIS. – Scott C. Blader, United States Attorney for the Western District of Wisconsin, announced that Michael Carroll, 50, Milwaukee, Wisconsin, pleaded guilty and was sentenced today by U.S. District Judge William H. Conley to 10 years in prison for conspiring to distribute heroin.

In September 2019, Carroll arranged to expand his drug-distribution operation from Milwaukee to Madison, Wisconsin.  He drove large quantities of heroin, some of which tested positive for fentanyl, from Milwaukee to Madison where he used another person to sell the heroin and collect his money.  Between September 13 and November 15, 2019, Carroll conspired to sell heroin to an undercover police officer on multiple occasions.  His relevant conduct included over 400 grams of heroin.  During the execution of search warrants where he stayed in Milwaukee, law enforcement agents located several hidden firearms.

Carroll has a lengthy criminal history dating back over 30 years, including gun crimes, drug crimes, and a reckless homicide where he shot an innocent person after pointing a gun at someone else.  At the time of his arrest, Carroll was on state supervision for three criminal cases, including the reckless homicide.  Judge Conley remarked that at age 50, Carroll had yet to make any meaningful deviation from a criminal lifestyle.

The charge against Carroll was the result of an investigation conducted by the Dane County Narcotics Task Force, the Wisconsin Department of Justice Division of Criminal Investigation, the Drug Enforcement Administration, and North Central HIDTA.  The prosecution of the case has been handled by Assistant U.S. Attorney Diane Schlipper.
