United States of America, Appellee, v. Roger Thomas Good Shield, Appellant, 5 F.3d 532 (8th Cir. 1993)

Roger Thomas Good Shield appeals the district court's¹  refusal to credit pretrial release time served in a community alcohol-drug center against the 97-month sentence imposed after he pleaded guilty to one count of aggravated sexual abuse in violation of 18 U.S.C. §§ 1153 and 2241(a) (1). As the district court noted, it had no authority to calculate a sentence credit at sentencing-that is a task assigned exclusively to the Attorney General and the Bureau of Prisons under 18 U.S.C. § 3585(b). See United States v. Wilson, 112 S. Ct. 1351 (1992). Accordingly, we affirm.
