OPINION
This case arises out of Jeffrey Len Melton’s conviction for being a felon in possession of a firearm and the district court’s imposition of a sentence enhancement un *1023 der the Armed Career Criminal Act (ACCA), 18 U.S.C. § 924(e). The district court concluded that Melton had the requisite three prior violent felony convictions to qualify for an enhancement under the ACCA. We agree and affirm.
Background
In 2002, federal agents arrested Melton after he arrived at a friend’s house in Wasilla, Alaska to pick up a handgun that Melton had mailed from Colorado. After a search of Melton’s vehicle revealed that he had a rifle in his back seat, Melton was charged in a two-count indictment for being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g).
Melton pled guilty under a written plea agreement to one of the felon-in-possession counts, and the Government agreed to dismiss the other count. The plea agreement contemplated that Melton’s sentence might be subject to the ACCA, which imposes a mandatory fifteen-year minimum sentence for violators of § 922(g) who have three prior convictions for violent felonies. Melton preserved the right to argue that he was not subject to the ACCA.
In its Presentence Investigation Report (“PSR”), the United States Probation Office concluded that Melton was subject to sentencing under the ACCA because he had at least four prior felony convictions that met the definition of “violent felony” under the statute: two 1976 convictions in Alexandria, Virginia for armed robbery and statutory burglary; a 1982 conviction in Arizona for residential burglary; and a 1984 conviction in Fairbanks, Alaska for Robbery and Nighttime Burglary in an Occupied Dwelling. The PSR also listed, as part of Melton’s criminal history, a 1990 conviction in Palmer, Alaska for second degree sexual abuse of a minor.
At his sentencing hearing, Melton conceded that the 1984 Fairbanks conviction qualified as a predicate felony under the ACCA. He contested the inclusion of the remaining convictions. The district court did not count the 1982 Arizona burglary as an ACCA- predicate felony because there was insufficient documentation of the conviction. The court concluded, however, that Melton still met the prerequisites for an ACCA sentencing enhancement because the other convictions qualified as violent felonies. Although the court found that either of the 1976 Virginia convictions could count as a violent felony, it counted only one of the convictions for sentencing purposes because the convictions did not occur on different occasions, as required under § 924(e)(1) of the ACCA. The court sentenced Melton to the statutory minimum of fifteen years.
Discussion
The ACCA’s penalty enhancement provisions are applicable if a defendant has been convicted, on separate occasions, of three violent felonies or serious drug offenses. 18 U.S.C. § 924(e)(1). A “violent felony” is defined as:
any crime punishable by imprisonment for a term exceeding one year ... that—
(i) has as an element the use, attempted use, or threatened use of physical force against the person of another; or
(ii) is burglary, arson, or extortion, involves use of explosives, or otherwise involves conduct that presents a serious potential risk of physical injury to another....
Id. at § 924(e)(2)(B).
Melton challenges the district court’s conclusion that his 1976 Virginia convictions for burglary and robbery, as well as his 1990 Alaska sexual abuse conviction, meet § 924(e)’s violent felony definition. In reviewing these convictions,
*1024
which we consider separately, we are guided by the Supreme Court’s directive in
Taylor v. United States,
I. 1976 Virginia Burglary Conviction
Under
Taylor,
we first determine the fact of conviction under a particular statute. Where the conviction is under a state burglary statute, we compare the elements listed in that statute with those of “burglary” as defined by the ACCA. Mindful that the definition of burglary may vary from state to state, the Supreme Court has held that the term “burglary,” as used in § 924(e)(2)(B)(ii), refers to “generic” burglary, meaning any offense that has “the basic elements of unlawful or unprivileged entry into, or remaining in, a building or structure, with intent to commit a crime.”
Taylor,
Had the district court been presented with Melton’s statute of conviction, a certified judgement of conviction, or some other documentary evidence that “clearly establishes” the burglary statute under which Melton was convicted,
United States v. Matthews,
The Government contends that the fact of conviction under § 18.1-89 is self-evident because Melton mentioned in his sentencing memorandum to the district court that he was convicted in 1976 under Va.Code § 18.1-89. This argument ignores that a lone reference in a defendant’s sentencing memorandum, without more, does not qualify as the type of documentary evidence that clearly establishes the fact of conviction under a particular statute.
See Sandoval-Venegas,
Further, even if the documentation were sufficient, the statutes cited by the Government do not contain elements that demonstrate Melton was convicted of generic burglary. The version of § 18.1-89 relied upon by the Government is a penalty provision for certain violations of § 18.1-88 and does not contain any elements of an offense at all. Section 18.1-88, now codified at § 18.2-90, is entitled “Entering dwelling house, etc. with intent to commit murder, rape or robbery”
1
and does contain substantive elements. However, § 18.1-88 is broadly defined, prohibiting breaking and entering not only into certain specified structures, but into ships, vessels, river crafts, and railroad cars, as well as automobiles used for human habitation. This definition exceeds the Supreme Court’s definition of generic burglary.
See Taylor,
The record contains no qualifying statute under which Melton was convicted. Nor does the record contain any judicially noticeable qualifying facts that would, under the second step of the
Taylor
analysis, establish that Melton’s conviction is a predicate conviction for enhancement purposes. The only documents in the record were a charging instrument stating that Melton burglarized the shop and storehouse of the Temple View Garage, and a PSR that reiterates the same information. The district court erroneously relied solely on the charging instrument’s description of the crime in concluding that Melton was convicted for a violent felony. We have consistently held that such documentation is insufficient to establish that a defendant pled guilty to the elements of the generic definition of a crime.
See, e.g., United States v. Corona-Sanchez,
II. 1976 Virginia Robbery Conviction
Although the ACCA does not specifically list robbery as a violent felony, the violent felony definition includes “any crime punishable by imprisonment for a term exceeding one year ... that has as an element the use, attempted use, or threatened use of physical force against the person of another.” 18 U.S.C. § 924(e)(2)(B)®. The government contends that Melton’s 1976 robbery conviction qualifies under this provision because the Virginia definition of robbery contains as an element the use or threatened use of force.
Virginia does not have a robbery statute listing the elements of the offense, relying instead on the common law definition of robbery.
See George v. Commonwealth,
We recognize that in
Taylor
the Supreme Court makes specific reference to categorical analysis of a
statute
of conviction. Indeed,
Taylor
as well as the many cases applying its holding generally stem from crimes of conviction that are defined by statute. This circumstance makes our categorical analysis of Melton’s Virginia robbery conviction unique, but it does not hinder our analysis. Where, as here, the state crime is defined by specific and identifiable common law elements, rather than by a specific statute, the common law definition of a crime serves as a functional equivalent of a statutory definition. This common-sense approach is consistent with Congress’s emphasis on using criminal elements, as opposed to statutory labels, to trigger the ACCA’s enhancement provisions.
See Taylor,
The record contains a valid judgment demonstrating that Melton was actually convicted of “robbery.” Looking to the common law definition of robbery as it has been articulated by the Virginia courts, we agree with the Fourth Circuit that this definition of robbery, on its face, has as an element the use or threatened use of physical force.
See United States v. Presley,
III. 1984 Sexual Abuse Conviction
Finally, we review Melton’s conviction for sexual abuse under Alaska Statute § 11.41.436(a), which provides in relevant part:
(a) An offender commits the crime of sexual abuse of a minor in the second degree if ...
(3) being 18 years of age or older, the offender engages in sexual contact with a person who is under 18 years of age, and the offender is the victim’s natural parent, stepparent, adopted parent, or legal guardian.
“Sexual contact” is defined as:
(i) knowingly touching, directly or through clothing, the victim’s genitals, anus, or female breast; or
*1027 (ii) knowingly causing the victim to touch, directly or through clothing, the defendant’s or victim’s genitals, anus, or female breast.
Alaska Stat. § 11.81.900(a)(57)(A).
The district court concluded that Melton’s conviction under § 11.41.436(a), which was supported in the record by a valid judgment, qualified under the ACCA as a crime that is “burglary, arson, or extortion, involves the use of explosives, or otherwise involves conduct that presents a serious potential risk of physical injury to another ....” 18 U.S.C. § 924(e)(2)(B)(ii) (emphasis added). We agree.
[6] Although we have not previously construed the “otherwise” clause of the ACCA in the context of sexual abuse convictions, our analyses in the United States Sentencing Guidelines (“U.S.S.G.”) context provide guidance. In
United States v. Wood,
More recently, in
United States v. Pereira-Salmeron,
Other circuits have similarly found the “otherwise” clauses of the ACCA and U.S.S.G. § 2L1.2 applicable where the conviction at issue involved sexual offenses against minors.
See, e.g., United States v. Meader,
We recognize that the statute before us encompasses all victims under the age of 18, and that some courts have hesitated in categorically equating the physical risks of sexual acts to minors of different age groups.
See, e.g., United States v. Thomas,
But we need not draw any bright lines here with regard to age or range of conduct because the Alaska sexual abuse statute contains an additional element that bears upon our analysis. The statute requires that “the offender is the victim’s natural parent, stepparent, adopted parent, or legal guardian.” Alaska Stat. § 11.41.436(a). This clause explicitly and implicitly excludes perpetrators that are close in age to the victim and narrows the class of offenders to those who bear parental authority over the victim.
3
Our precedents recognize that such factors as age and the authority position of the offender contribute to the risks inherent in the sexual abuse of a minor.
See Wood,
Other courts also have acknowledged the unique nature of laws that involve, or may involve, parent-child offenses.
See United States v. Vigil,
*1029 Acknowledging the special and unique dynamic of a parent-child relationship and in view of these authorities, we have no trouble concluding that Melton’s crime of sexual abuse “involve[d] conduct that presents a serious potential risk of physical injury.” § 924(e)(2)(B)(ii). The sexual contact, by definition, was committed against a minor. The power disparity inherent in that act, coupled with the fact that Melton was in a position of parental control over the victim, created a situation of dominance and control that brought with it an inherent risk of physical injury. Melton’s sexual abuse conviction constituted a conviction for a crime of violence within the meaning of § 924(e). 4
Conclusion
Although Melton’s 1976 Virginia burglary conviction did not qualify as a predicate felony under the ACCA, we affirm the judgment of the district court that Melton has the requisite three prior violent felony convictions to qualify for an enhancement under 18 U.S.C. § 924(e).
AFFIRMED.
Notes
. At the time of Melton’s indictment and conviction, §§ 18.1-88 and §§ 18.1-89 had already been recodified at §§ 18.2-90 and 18.2— 91, respectively. This statutory substitution has no bearing on our analysis, however, because even if we refer to the statutory definitions urged by the Government, the burglary does not qualify categorically as a violent felony.
. "Crime of violence” is defined in the Application Notes to § 2L1.2:
"Crime of violence”—
(I) means an offense under federal, state, or local law that has as an element the use, attempted use, or threatened use of physical force against the person of another; and (II) includes murder, manslaughter, kidnapping, aggravated assault, forcible sex offenses (including sexual abuse of a minor), robbery, arson, extortion, extortionate extension of credit, and burglary of a dwelling.
U.S.S.G. § 2L1.2, cmt. n. l(B)(ii).
. Alaska Stat. § 11.41.436(a) also contains an explicit requirement that offenders be 18 years of age or older. Although it would be possible for an offender, at age 18 or 19, to qualify under the statute as a natural parent, stepparent, adopted parent, or legal guardian, as a practical matter, the vast majority of parental offenders would be significantly older than the victim.
. The Government directs us to the police affidavit that was submitted in support of the original criminal complaint against Melton. That document states that Melton victimized his thirteen-year-old step-daughter. Were we able to consider these facts, the victim’s precise age might play a stronger role in our analysis. But we are not permitted, under the categorical approach, to consider the underlying facts of the case,
Taylor,
