Dist.Ct. erred in sentencing defendant to 84-month term of incarceration on drug distribution charge, where said sentence was based, in part, on imposition of leadership. Organizer enhancement under 3B1.1(c) of USSG. Record failed to support Dist. Ct.’s finding that defendant served as leader of Minneapolis drug operation, or that defendant managed two others to help him transport drugs at time of defendant’s arrest, where: (1) record showed, at best, that defendant was middleman in Minneapolis drug operation who exercised no control over unknown group of individuals; and (2) record showed that two individuals who assisted defendant in transporting drugs at time of defendant’s arrest actually worked for another individual, and that defendant did not actually control said individuals. Fact that defendant was given below-guidelines sentence did not preclude instant remand for new sentencing hearing, where record did not indicate what Dist. Ct. would have done had it considered correct guideline range without imposition of instant enhancement.
