OPINION

Appellant Francisco Salgado Martinez (Martinez) challenges the district court’s denial of his motion to dismiss an indictment alleging that he was found in the United States subsequent to an order of removal in violation of 8 U.S.C. § 1326 . Martinez asserts that the underlying removal order was invalid because his conviction for third-degree child molestation in violation of Wash. Rev.Code § 9A.44.089 (2001) was not an aggravated felony. Because recent developments in the law support Martinez’s claim, we reverse the district court’s denial of Martinez’s motion to dismiss the indictment.

I. BACKGROUND

In 2001, Martinez pled guilty to- third-degree child molestation in violation of Wash. Rev.Code § 9A.44.089. Martinez, a lawful permanent resident, was subsequently served with a notice to appear because his conviction was an aggravated felony “relating to ... the sexual abuse of a minor.” 8 U.S.C. § 1101 (a)(43)(A). The Immigration Judge ordered Martinez’s removal from the United States based on his admission to the charges in the notice to appear.

In 2011, Martinez was indicted for being found in the United States subsequent to his removal in violation of 8 U.S.C. § 1326 . Martinez filed a motion to dismiss the indictment premised on a challenge to the validity of the underlying removal order. Martinez asserted that his removal violated his due process rights because his state conviction was not an aggravated felony. According to Martinez, Washington’s third-degree child molestation offense was broader than the generic offense of sexual abuse of a minor because it criminalized sexual contact involving the touching of a minor over clothing.

The district court denied Martinez’s motion to dismiss the indictment. The district court concluded that Martinez’s removal comported with due process requirements because Martinez’s third-degree child molestation conviction categorically qualified as sexual abuse of a minor. Relying on our decision in Jimenez-Juarez v. Holder, 635 F.3d 1169 (9th Cir.2011), the district court opined that Martinez’s conviction was a categorical match to the generic offense of sexual abuse of a minor because, under Jimenez-Juarez , the act of sexual touching of a 14- or 15-year, old victim by one who is at least 48 months older constitutes, at a minimum, “maltreatment of a child and impairs the child’s mental well-being,” id. at 1171 , and was therefore categorically “abuse.” Id.

Martinez filed a timely notice of appeal.

II. STANDARD OF REVIEW

‘We review de novo the denial of a motion to dismiss an indictment under 8 U.S.C. § 1326 when the motion is based on alleged due process defects in an underlying deportation proceeding.” United States v. Alvarado-Pineda, 774 F.3d 1198, 1201 (9th Cir.2014) (citation omitted).

III. DISCUSSION

Martinez contends that his prior removal was invalid because his third-degree child molestation conviction did not categorically qualify as an aggravated felony.

“To convict an alien criminal defendant of illegal reentry under 8 U.S.C. § 1326 , the government must prove that the alien left the United States under order of exclusion, deportation, or removal, and then illegally reentered.” Id. (citation omitted). “A noncitizen charged with illegal reentry therefore has a Fifth Amendment right to collaterally attack his removal order because the removal order serves as a predicate element of his conviction .... ” Id. (citations and internal quotation marks omitted). “An underlying order is fundamentally unfair if (1) a defendant’s due process rights were violated by defects in his underlying deportation proceeding, and (2) he suffered prejudice as a result of the defects.” Id. (citation and internal quotation marks omitted). Where a prior removal order is premised on the commission of an aggravated felony, a defendant who shows that the crime of which he was previously convicted was not, in fact, an aggravated felony, has established both that his due process rights were violated and that he suffered prejudice as a result. See United States v. Camacho-Lopez, 450 F.3d 928, 930 (9th Cir.2006).

In ascertaining whether Martinez’s removal was validly premised on his commission of an aggravated felony, “we employ the categorical approach. That is, we compare the elements of the statute forming the basis of [Martinez’s] conviction with the elements of the generic crime.” Alvarado-Pineda, 774 F.3d at 1202 (citation and internal quotation marks omitted). “The prior conviction qualifies as the generic offense only if the statute’s elements are the same as, or narrower than, those of the generic offense.” Id. (citation and alteration omitted). “A state offense qualifies as a generic offense — and therefore, in this case, as an aggravated felony — only if the full range of conduct covered by the state statute falls within the meaning of the generic offense.” Id. (citation, alteration, and internal quotation marks omitted).

At the time of Martinez’s conviction, Wash. Rev.Code § 9A.44.089 (2001) provided:

Under Washington law, “ ‘[s]exual contact’ means any touching of the sexual or other intimate parts of a person done for the purpose of gratifying sexual desire of either party or a third party.” Wash. Rev. Code § 9A.44.010(2) (2001) (internal quotation marks omitted).

We conclude that Martinez’s conviction for third-degree child molestation does not categorically qualify as an aggravated felony. An aggravated felony is defined by 8 U.S.C. § 1101 (a)(43)(A), inter alia, as “murder, rape, or sexual abuse of a minor[.]” The issue raised in this appeal is whether the Washington offense of third-degree child molestation constitutes “sexu al abuse of a minor.” Id. In a series of opinions, we have articulated an evolving generic definition of this offense. In Estrada-Espinoza, v. Mukasey, 546 F.3d 1147 (9th Cir.2008) (en banc), overruled on other grounds by United States v. Aguila-Montes de Oca, 655 F.3d 915 (9th Cir.2011) (en banc) (per curiam), abrogated by Descamps v. United States , — U.S. —, 133 S.Ct. 2276 , 186 L.Ed.2d 438 (2013), we held that “the generic offense of ‘sexual abuse of a minor’ requires four elements: (1) a mens rea level of knowingly; (2) a sexual act; (3) with a minor between the ages of 12 and 16; and (4) an age difference of at least four years between the defendant and the minor.” Estrada-Espinoza, 546 F.3d at 1152 (citation and internal quotation marks omitted).

In United States v. Medina-Villa, 567 F.3d 507 (9th Cir.2009), we determined that the generic offense of sexual abuse of a minor was not limited to the elements delineated in Estradar-E spinoza. Instead, we reasoned that Estrada-Espinoza’s definition “encompassed statutory rape crimes only — that is, sexual offenses involving older as well as younger adolescents, not crimes prohibiting conduct harmful to younger children specifically....” Id. at 514 . We have since interpreted Medina-Villa and its progeny as recognizing “a residual category of ‘sexual abuse of a minor’ ... that encompasses statutes where (1) the conduct proscribed is sexual; (2) the statute protects a minor; and (3) the statute requires abuse.... ” United States v. Gomez, 757 F.3d 885, 904 (9th Cir.2014) (citation, alteration, and some internal quotation marks omitted).

In Gomez , we applied this definitional framework in concluding that an Arizona statute prohibiting “attempted sexual conduct with a minor under the age of 15” was not categorically an offense involving sexual abuse of a minor. Id. at 900, 902 . At issue in Gomez was whether the defendant’s conviction for violating Ariz.Rev. Stat. § 13-1405 warranted a sixteen-level enhancement under U.S.S.G. § 2L1.2(b)(l)(A)(ii) as a crime of violence. See id. at 902. Pursuant to A.R.S. § 13-1405:

In determining that the Arizona statute was missing elements of the generic definition of sexual abuse of a minor, we held:

Id. at 904 (citations and some internal quotation marks omitted).

We similarly conclude that Wash. Rev. Code § 9A.44.089 (2001), an indivisible statute, does not categorically meet the generic definition of sexual abuse of a minor due to its missing elements. Indeed, the Washington statute “criminalizes a broader swath of conduct than the relevant generic offense,” Descamps, 133 S.Ct. at 2281 , because it criminalizes touching over clothing as opposed to the generic offense’s requirement of skin-to-skin contact. See State v. Soonalole, 99 Wash.App. 207 , 992 P.2d 541 , 544 & n. 13 (2000) (holding that “the fondling and thigh rubbing over the victim’s clothes” constituted a separate act of third-degree child molestation for double jeopardy purposes); see also United States v. Castro, 607 F.3d 566, 570 (9th Cir.2010), as amended (holding that a California statute prohibiting lewd and lascivious acts on a child was categorically broader than the generic definition for sexual abuse of a minor because “[l]ewd touching [under the state statute] can occur through a victim’s clothing and can involve any part of the victim’s body”).

“In the. absence of a categorical match, we may, in some circumstances, apply the modified categorical approach, under which we consider whether certain documents in the record or judicially noticeable facts show that the conviction qualifies as an aggravated felony....” Aguilar-Turcios v. Holder, 740 F.3d 1294, 1301 (9th Cir.2014) (citation and internal quotation marks omitted). However, we are unable to resort to the modified categorical approach because the Washington statute “has a single, indivisible set of elements” and is missing elements of the generic definition of sexual abuse of a minor. Descamps, 133 S.Ct. at 2282 ; see also Gomez, 757 F.3d at 903-04 . The Washington offense is missing the element of “abuse”' as required under the Medina-Villa standard, because it does not require “abuse” based on “physical, or psychological .harm in light of the age of the victim in question.” Medina-Villa, 567 F.3d at 513 (citations and internal quotation marks omitted). The Washington offense is also missing the element of a “sexual act” as required under the Estrada-Espinoza analysis, because a conviction may be based on touching over clothing while the generic offense “requires, at a minimum, an intentional touching, not through the clothing, of a minor’s genitalia.” Castro, 607 F.3d at 570 . Because the state offense is missing elements of sexual abuse of a minor, we may not consult the relevant documents relating to Martinez’s conviction in ascertaining whether he committed an aggravated felony. See United States v. Aguilera-Rios, 769 F.3d 626, 637 (9th Cir.2014), as amended (“Because the statute is missing an element of the generic crime, our inquiry ends here — we do not undertake a modified categorical analysis.”) (citation and alterations omitted).

Applying Jimenez-Juarez , the district court- reached an opposite conclusion and held that Martinez’s prior conviction was categorically an aggravated felony because it encompassed “abuse.” However, in Jimenez-Juarez , we confined our analysis to whether the petitioner’s conviction under Wash. Rev.Code § 9A.44.089 constituted “child abuse” as defined in 8 U.S.C. § 1227 (a)(2)(E), and did not otherwise address whether the offense was an aggravated felony involving sexual abuse of a minor. See Jimenez-Juarez, 635 F.3d at 1170 & n. 1. We therefore applied the less stringent definition for child abuse which relates to “any offense that (1) involves an intentional, knowing, reckless, or criminally negligent act or omission that (2) constitutes maltreatment of a child or that impairs a child’s' physical or mental well-being, including sexual abuse or exploitation.” Id. at 1171 (citation omitted). In contrast, the generic offense of sexual abuse of a minor categorically corresponds only to those crimes that fit the narrower definitions set out in Estradar-Espinoza (for statutory rape crimes) and Medina-Villa (for crimes of “abuse”).

IV. CONCLUSION

We conclude that Martinez was not removable based on an aggravated felony. A conviction premised on a violation of Wash. Rev.Code § 9A.44.089 (2001) does not categorically meet the generic definition of sexual abuse of a minor due to the missing elements in the statutory provision. Because the Washington statute is indivisible, we may not resort to the modified categorical approach in determining whether Martinez’s conviction constituted an aggravated felony that would warrant his removal. Reversal of the district court’s denial of Martinez’s motion to dismiss the indictment is justified because the government is unable to demonstrate, as required for a violation of 8 U.S.C. § 1326 , that Martinez was removed pursuant to a valid removal order. See Alvarado-Pineda, 774 F.3d at 1201 (articulating that “the removal order serves as a predicate element of [the defendant’s] conviction”) (citations omitted).

REVERSED and REMANDED.

. Gomez and Castro apply to Martinez's collateral challenge to the underlying removal order because his appeal "concerns not the duty to inform the noncitizen of his eligibility for relief in a removal proceeding, but whether he was removable at all.” Aguilera-Rios, 769 F.3d at 631 (emphases in the original). . The Notice To Appear in this case charged Martinez as removable only because he had committed an aggravated felony as defined in 8 U.S.C. § 1101 (a)(43)(A), for a crime of “sexual abuse of a minor.''
