Ct. of Appeals dismissed defendant’s appeal alleging that his guilty plea on drug charges was not knowingly given since Dist. Ct. did not explain prior to imposition of 96-month sentence that said sentence would be served consecutively to defendant’s undischarged state sentence. Guilty plea contained waiver of any appellate rights that pertained to defendant’s sentence, and record showed that Dist. Ct. conducted thorough plea colloquy that covered instant waiver. Moreover, Dist. Ct. was not required to advise defendant that his federal sentence might be imposed consecutively to his undischarged state sentence prior to accepting defendant’s guilty plea.
