SIOUX CITY, Iowa (AP) – A 26-year-old Iowan has been given 80 months in federal prison for two more drug convictions.  Federal prosecutors say Roscoe Perry, of Sioux City, pleaded guilty to selling crack cocaine and conspiracy. Perry admitted selling cocaine from October 2011 through February this year. Prosecutors say Perry traveled to Omaha, Neb., to obtain the crack cocaine he sold in Sioux City.  Perry had been convicted in November 2006 in U.S. District Court in Nebraska for selling crack.  Perry must serve eight years of supervised release after he leaves prison.
