Notice: Eighth Circuit Rule 28a(k) Governs Citation of Unpublished Opinions and Provides That They Are Not Precedent and Generally Should Not Be Cited Unless Relevant to Establishing the Doctrines of Res Judicata, Collateral Estoppel, the Law of the Case, or if the Opinion Has Persuasive Value on a Material Issue and No Published Opinion Would Serve As Well.united States of America, Appellee, v. Allie Harper, Appellant, 111 F.3d 136 (8th Cir. 1997)

In this direct criminal appeal, Allie Harper challenges the 324-month sentence imposed by the district court¹  following his guilty plea to possessing with intent to distribute in excess of fifty grams of a mixture or substance containing cocaine base, in violation of 21 U.S.C. § 841(a) (1). We affirm.

We reject Harper's contention on appeal that the district court erred in calculating his base offense level absent "proof by a preponderance of the evidence that the form of cocaine base possessed by Harper was actually crack." Harper did not contend below that the cocaine base he possessed was something other than crack cocaine. Thus, his present challenge is subject to plain error review. See Fritz v. United States, 995 F.2d 136, 137 (8th Cir. 1993), cert. denied, 510 U.S. 1075 (1994). We conclude there was no plain error here, as the record demonstrates Harper was aware that he was pleading guilty to an offense involving crack cocaine. The unchallenged offense conduct portion of Harper's presentence report (PSR) clearly showed that Harper possessed crack cocaine with intent to distribute. Further, Harper implicitly conceded to the type of cocaine involved by agreeing to the PSR's determination of his base offense level. See United States v. LaRoche, 83 F.3d 958, 959 (8th Cir. 1996) (per curiam) (district court entitled to accept as true factual statements in PSR to which defendant does not object). Finally, Harper's objection at sentencing to the enhanced penalties for crack versus powder cocaine revealed his awareness that his plea was to a crack-cocaine offense. Cf. United States v. Bush, 70 F.3d 557, 562 (8th Cir. 1996) (10th Cir. 1995) (sentencing for cocaine base upheld where clear from defendant's admissions that he intended to plead guilty to offense involving cocaine base, not cocaine powder), cert. denied, 116 S. Ct. 795 (1996). Accordingly, we affirm.
