Manuel Antonio Mata appeals the sentence he received following his guilty-plea conviction for distributing heroin within 1,000 feet of a school, in violation of 21 U.S.C. §§ 841(a)(1) and 860; for using a firearm in connection with a drug-trafficking offense, in violation of 18 U.S.C. § 924(c)(1); for being an unlawful user of a controlled substance in possession of a firearm, in violation of 21 U.S.C. § 922(g)(3); and for being a felon in possession of a firearm, in violation of 21 U.S.C. § 922(g)(1). He first contends that the district court erred in sentencing him as an aimed career criminal under 18 U.S.C. § 924(e) and U.S.S.G. § 4B1.4.

*720 Because Mata did not object to the armed-career-criminal enhancement in the district court, review is for plain error. See United States v. Vonn, 535 U.S. 55, 59, 122 S.Ct. 1043, 152 L.Ed.2d 90 (2002). Mata has demonstrated that the enhancement was plainly erroneous because the record does not establish that his prior conviction for simple possession of cocaine under Texas law was a “serious drug offense” or that his prior conviction for theft under Texas law was a “violent felony” within the meaning of the statute so as to qualify as predicate offenses. See 18 U.S.C. §§ 924(e)(2)(A) and (B). Even assuming that the two other prior convictions pleaded in the indictment constitute valid predicate offenses, three predicate offenses are required by the statute. See 18 U.S.C. § 924(e)(1). The error affected Mata’s substantial rights because, without the enhancement, he would have been subjected to a lower sentence.

Mata next renews the argument, preserved in the district court, that his constitutional rights were violated when the district court assessed a two-point adjustment, pursuant to U.S.S.G. § 2K2.1(b)(4), based on judicially determined facts, citing Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004). In light of the Supreme Court’s recent decision in United States v. Booker, — U.S. -, 125 S.Ct. 738, 756, 160 L.Ed.2d 621 (2005), the two-level adjustment violated Mata’s Sixth Amendment right to a trial by jury, and the Government has not carried its burden of demonstrating that the error was harmless. Accordingly, Mata’s sentence is VACATED, and the case is REMANDED FOR RESENTENCING. See United States v. Pineiro, 410 F.3d 282, 286-87 & n. 4 (5th Cir. 2005); United States v. Akpan, 407 F.3d 360, 377 (5th Cir. 2005); United States v. Mares, 402 F.3d 511, 520 n. 9 (5th Cir. 2005), petition for cert. filed (March 31, 2005) (No. 04-9517).
