Police said a Dubuque man sold drugs to an individual who later died. 36-year-old Shon Perkins of Dubuque was arrested at 8:04 p.m. Monday in the 300 block of 12th Street on a warrant charging a controlled substance violation. Court documents state Perkins has been the subject of an investigation by the Dubuque Drug Task Force following “credible and corroborated information” that he sold heroin and/or fentanyl that ultimately led to a suspected drug overdose death. In June, documents state Perkins sold three bags of fentanyl to a confidential informant working for the task force as part of the investigation. The total weight of the drugs was 2.92 grams, not including the packaging.
