In this appeal, we must consider whether the knowing possession of a handgun in violation of a Texas statute prohibiting the possession of a deadly weapon in a penal institution is a crime of violence under the United States Sentencing Guidelines (“U.S.S.G.”), and whether the district court’s classification of the defendant’s pri- or convictions as crimes of violence violates the defendant’s Sixth Amendment rights under
United States v. Booker,
I. FACTUAL AND PROCEDURAL BACKGROUND
On June 23, 2005, pursuant to an oral plea agreement, Defendant-Appellant Ramiro Rodriguez-Jaimes (“Rodriguez-Jaimes”) pleaded guilty to one count of conspiracy to possess with intent to distribute 500 grams or more of cocaine and 50 grams or more of cocaine base, in violation of 21 U.S.C. §§ 841(a) and 846, and one count of knowingly carrying a firearm during and in relation to a drug-trafficking crime, in violation of 18 U.S.C. § 924(c)(1). The presentence investigation report (“PSR”) recommended a base offense level of thirty-seven because the probation officer determined that Rodriguez-Jaimes was a career offender pursuant to U.S.S.G. § 4B1.1 in that he previously had been convicted in Texas state court of aggravated robbery and possession of a deadly weapon in a penal institution. After he received a three-level adjustment for acceptance of responsibility, Rodriguez-Jaimes’s total offense level was thirty-four. This оffense level, combined with a Category VI criminal history score, resulted in a guideline sentencing range of 262 to 327 months.
Rodriguez-Jaimes filed two objections to the PSR, both of which related to his classification as a career offender. First, he claimed that his prior cоnviction for possession of a deadly weapon in a penal institution was not a crime of violence un *285 der U.S.S.G. § 4B1.1. Second, he argued that the sentencing enhancement violated his constitutional rights.
The district court overruled these objections and also deniеd Rodriguez-Jaimes’s motion for a downward departure. On January 25, 2006, the district court sentenced Rodriguez-Jaimes to 290 months in prison and four years of supervised release. Rodriguez-Jaimes timely appealed.
II. DISCUSSION
A. Career Criminal Offender Enhancement
Rodriguez-Jaimes argues that the district court erred in concluding thаt his prior conviction for possession of a deadly weapon in a penal institution qualifies as a crime of violence for purposes of the career criminal offender enhancement under U.S.S.G. § 4B1.1. Section 4B1.1 of the Sentencing Guidelines provides for an increased sentence to be imposed upon career criminal offenders. A defendant is a career criminal offender under the Guidelines if:
(1) the defendant was at least eighteen years old at the time the defendant committed the instant offense of сonviction;
(2) the instant offense of conviction is a felony that is either a crime of violence or a controlled substance offense; and
(3) the defendant has at least two prior felony convictions of either a crime of violence or a cоntrolled substance offense.
U.S.S.G. § 4Bl.l(a). Section 4B1.2(a) defines a “crime of violence” as
any offense under federal or state law, punishable by imprisonment for a term exceeding one year, that—
(1) has as an element the use, attempted use, or threatened use of physical force against the person of another, or
(2) is burglary of a dwelling, arson, or extortion, involves the use of explosives, or otherwise involves conduct that presents a serious potential risk of physical injury to another.
The application notes to the Guidelines further explain that:
“Crime of violence” includes murder, manslaughter, kidnapping, aggravated assault, forcible sex offenses, robbery, arson, extortion, extortionate extension of credit, and burglary of a dwelling. Other offenses are included as “crimes of violence” if (A) that offense has as an element the use, attempted use, or threatened use of physical force against the person of another, or (B) the conduct set forth (ie., expressly charged) in the count of which the defendant was convicted involved use of explosives (including any explosive material or destructive device) or, by its nature, presented a serious potential risk of physical injury to another.
Id. § 4B1.2 cmt. n.l.
Rodriguez-Jaimes contends that his pri- or conviction for possession of a deadly weapon in a penal institution does not qualify as a crime of violence because it does not meet either definition under U.S.S.G. § 4B1.2(a). 1 The government concedes that Rodriguez-Jaimes’s prior conviction does not qualify as a crime of violence under U.S.S.G. § 4B1.2(a)(l) be *286 cause the statute under which Rodriguez-Jaimes was convicted, Texas Penal Code § 46.10, 2 does not have “as an element the use, attempted use, or threatened use of physical force against the person of another.” Instead, the government claims that Rodriguez-Jaimes’s prior conviction for possession of a deadly weapon in a penal institution falls within the “otherwise involves conduct that presents a serious potential risk of physical injury to another” clause of § 4B1.2(a)(2).
Whether a defendant’s prior conviction can be classified as a crime of violence under the Sentencing Guidelines is a question of law.
See United States v. Guevara,
Under § 4B1.2(a)(2), “a categorical approach is takеn to determine whether the charged count of conviction, by its nature, presented a serious potential risk of physical injury.”
United States v. Insaulgarat,
The indictment in this case reveals that:
Ramiro Rodriguez Jaimes, on or about the 13th day of June, One Thousand Nine Hundred and Ninety-Four, and anteriоr to the presentment of this indictment, in the County of Jefferson and State of Texas, did then and there while confined in a penal institution, namely: Jefferson County Detention Facility, intentionally and knowingly possess and conceal a deadly weapon, to-wit: a firearm, namеly, a handgun, that in the manner of its use and intended use was capable of causing serious bodily injury and death ....
Thus, the question we face under our categorical approach is whether the specific conduct charged in the indictment by its nature poses a seriоus potential risk of physical injury. Specifically, we must decide whether intentionally and knowingly possessing and concealing a handgun while confined in a penal institution constitutes conduct which by its nature presents a serious potential risk of physical injury to another.
This court recently decided a similar issue. In
United States v. Robles-Rodriguez,
No. 05-41768,
In
Robles-Rodriguez,
the court also considered the same argument that Rodriguez-Jaimes presents here, namely that the crime of possession of a deadly weapon in prison is similar to the crime of unlawful possession of a firearm by a felon outside of prison, the latter of which is not considered a “crime of violence” for purposes of determining whether a defendant is career criminаl offender.
Id.
at *3. In rejecting this argument, we emphasized that “the possession offense occurs in prison, rather than in the outside world. That fact creates a perpetual risk of injury and precludes any legitimate reasons that a non-incarcerated individual сould have for possessing a weapon (e.g., recreation).”
Id.; see also Vahovick,
Although Robles-Rodriguez involved the knowing possession of a metal shank in a federal correctional facility, its reasoning applies with equal force here. We therefore adopt the reasoning of Robles-Rodriguez in holding that the knowing possession of a handgun in violation of a Texas statute prohibiting the possession of a deadly weapon in a penal institution is a crime of violence under U.S.S.G. § 4B1.2(a)(2). Accordingly, we conclude that the district court did not err in enhancing Rodriguez-Jaimes’s sentence as a career criminal offender under the Guidelines. 3
*288 B. Sixth Amendment Claim
Rodriguez-Jaimes also contends that the district court’s classification of his prior convictions as crimes of violence violated his Sixth Amendment rights under
Booker,
[t]he question Booker answered in the affirmative was “[wjhether the Sixth Amendment is viоlated by the imposition of an enhanced sentence under the United States Sentencing Guidelines based on the sentencing judge’s determination of a fact (other than a prior conviction) that was not found by the jury or admitted by the defendant.”
Id.
at 261 (quoting
Booker,
Our decision in
Guevara
forecloses Rodriguez-Jaimes’s constitutional claim. Absent an en banc or intervening Supreme Court decision, one panel of this court may not overrule a prior panel’s decision.
See United States v. Treft,
III. CONCLUSION
For the foregoing reasons, we AFFIRM Rodriguez-Jaimes’s judgment of conviction and sentence as imposed by the district court.
AFFIRMED.
Notes
. There is no dispute that Rodriguez-Jaimes was over eighteen years old at the time of the instant offense or that the instant offense is a felony that is a controlled substance offense for purposes of U.S.S.G. § 4B1.1. In addition, Rodriguez-Jaimes does not dispute that his prior conviction in Texas state court for aggravated robbery qualifies as a crime of violence.
. The statute provides in full:
(a) A person commits an offense if, while confined in a
penal institution, he intentionally, knowingly, or recklessly:
(1) carries on or about his person a deadly weapon; or
(2) possesses or conceals a deadly weapon in the penal institution.
(b) It is an affirmative defense to prosecution under this section that at the time of the offense the actor was engaged in conduct authorized by an employee of the penal institution.
(c) A person who is subject to prosecution undеr both this section and another section under this chapter may be prosecuted under either section.
(d) An offense under this section is a felony of the third degree.
Tex. Penal Code Ann. § 46.10 (Vernon 2003).
. We also reject Rodriguez-Jaimes's argument that the district court’s classification of Rodriguez-Jaimes аs a career criminal offender violated the Supreme Court’s holding in
