A Madison man will spend nine years in federal prison after pleading guilty to conspiracy to distribute more than 100 grams of heroin. The U-S Attorney’s Office says 33-year-old Darnell Brunt was charged after the heroin overdose of Victor Spidell in May 2017. Prosecutors say Spidell died from using heroin laced with fentanyl that he bought from Brunt. The Dane County Narcotics Task Force made four heroin buys from Brunt using an undercover officer. A search of Brunt’s apartment in Sun Prarie led to the seizure of 125 grams of heroin, some laced with fentanyl, along with a loaded firearm. The judge gave Brunt a nine-year sentence due to a history of drug dealing.
