Madison Man Sentenced to More Than 4 Years for Illegally Possessing a Firearm

MADISON, WIS. - Chadwick M. Elgersma, United States Attorney for the Western District of Wisconsin, announced that Marcus Brinkley, 23, Madison, Wisconsin, was sentenced last week by Chief U.S. District Judge James D. Peterson to 54 months in federal prison for possessing a firearm as a felon. Brinkley's prison term will be followed by three years of supervised release. Brinkley pleaded guilty to this charge on February 27, 2026.

Brinkley was arrested following a controlled delivery of narcotics. In Brinkley's motel room, law enforcement recovered a loaded handgun on the nightstand. Brinkley is prohibited from legally possessing firearms or ammunition due to prior felony convictions.

At sentencing, Judge Peterson commented on the nature of Brinkley's prior convictions and his conduct in this case to highlight the danger Brinkley posed to the public. To arrive at the sentence, Judge Peterson balanced these aggravating factors with the defendant's young age.

The charge against Brinkley was the result of an investigation conducted by the Dane County Narcotics Task Force and the ATF Madison Crime Gun Task Force, which is comprised of federal agents from ATF and task force officers from state and local agencies throughout the Western District of Wisconsin. Assistant U.S. Attorney Louis Glinzak prosecuted this case.

Federal prosecutions by the U.S. Department of Justice involving drugs and guns are part of the U.S. Department of Justice's Operation Take Back America. Operation Take Back America is a nationwide initiative that marshals the full resources of the Department to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations, and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department's Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).
