A Dubuque man is pleading guilty to providing a fentanyl mix that led to a fatal overdose last summer. Reports show 29-year-old Carl Watkins is facing a mandatory minimum sentence of 20 years in federal prison for distribution of controlled substances resulting in death. He admitted to meeting a woman for a heroin deal in August 2019. The woman took the drugs, lost consciousness and later died. Police found a substance in her bedroom that tested positive for the fatal mix. The Dubuque Drug Task Force set up a controlled buy from Watkins the next day and he was arrested.
