SIOUX CITY, Iowa (AP) – Authorities say a Nebraska man who supplied crack cocaine that was sold in northwest Iowa has been given 15 years in federal prison. Federal prosecutors say 32-year-old Tuwane English had pleaded guilty in Sioux City to conspiring to distribute crack cocaine. English would sell crack in Omaha, Neb., to people who would sell it in the Sioux City area. English, of Omaha, must serve eight years of supervised release when he leaves prison. He was sentenced on Monday. He’d already been convicted of conspiracy to distribute narcotics in Nebraska.
