Court held that “[ojther than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt.” Id. at 490, 120 S.Ct. 2348. Because the jury had made no drug quantity finding, the district court sentenced Johnson to 240 months of imprisonment — the statutory maximum penalty for this offense without considering drug quantity. See 21 U.S.C. § 841(b)(1)(C); U.S. Sentencing Guidelines Manual § 5Gl.l(a) (1998) (“Where the statutorily authorized maximum sentence is less than the minimum of the applicable guideline range, the statutorily authorized maximum sentence shall be the guideline sentence.”); see also United States v. Aguayo-Delgado, 220 F.3d 926, 933 (8th Cir.) (<HOLDING>), cert. denied, 531 U.S. 1026, 121 S.Ct. 600,
holding that where the indictment charged drug quantity but drug quantity was not submitted to the jury the district court erred in using drug quantity to increase the penalty beyond the twentyyear maximum of  841b1c holding that statutory maximum is twenty years when drug quantity is not charged as element of offense and found by jury beyond a reasonable doubt holding that when the indictment charges that a certain minimum quantity of drugs is involved in the offense proof of that quantity is a fourth element of the offense holding that a sentence is proper as long as it is within the statutory range prescribed for the offense without regard to drug quantity holding no merit to ineffective assistance of counsel claim with regard to sentence imposed where record demonstrated defendants sentence was within range prescribed by relevant sentencing guidelines
