Investigators from the Duluth Police Department and Lake Superior Drug and Violent Crime Task Force seized more than 28 grams of fentanyl, more than 93 grams of methamphetamine, $3,974 in cash, eight firearms and ammunition as the result of a search warrant executed Wednesday at an apartment in the 3200 block of West Michigan Street.

Authorities arrested two men as a result of a months-long investigation that led to the issuance of the search warrant: Robert Anthony Winston, 30 of Detroit, and Marice Darnell King, 53, of Duluth. Both suspects remain in the St. Louis County Jail.

On Friday, Winston was charged with first-degree sale of a controlled substance (methamphetamine) and second-degree sale of a controlled substance (fentanyl). Meanwhile, King was charged with aiding and abetting second-degree sale of a controlled substance (fentanyl).

Winston's bail was set at $200,000, and King's was set at $50,000.

At the time of his latest arrest, Winston was free on $100,000 bail, as a suspect already facing a charge of second-degree assault in connection with a shooting in Duluth. This latest incident marks Winston's fifth arrest in the past four months by the Duluth Police Department and the Task Force for Drugs and Violent Crime. Prior to arriving in Duluth, he was convicted in Michigan for receiving/concealing a motor vehicle, delivery/manufacture of a controlled substance, and in Kentucky for possession of a controlled substance in the first degree.

King's rap sheet is shorter, with previous felony convictions in Minnesota for domestic assault and fifth-degree possession of a controlled substance.

Editor's note: This story has been updated to correct Winston's bail amount to $200,000.
