APPEAL FROM THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF MASSACHUSETTS

LYNCH, Circuit Judge. Michael Mao appeals from a 121-month sentence imposed after he pled guilty to conspiracy to commit drug trafficking and money laundering. On August 14, 2024, Mao pled guilty to conspiring with others to distribute controlled substances from at least December 2019 through May 2021 in the Virginia correctional facility where he was incarcerated. His appeal challenges the district court's determination that he was a "career offender" under the United States Sentencing Guidelines (the "Guidelines" or "U.S.S.G."), on two grounds. First, he argues that his prior Virginia conviction under Va. Code Ann. § 18.2-53.1 for using or displaying a firearm in the commission of a robbery was not a "crime of violence" as referenced in U.S.S.G. § 4B1.1. Second, he contends that his conviction for conspiring to distribute drugs was not a "controlled substance offense" under the Guidelines and that this court should overrule its precedent to the contrary. We hold Mao's first challenge is without merit and his second is foreclosed by the law-of-the-circuit doctrine, and even so, we see no reason to depart from our precedent. We affirm his sentence.

I.

Because Mao pled guilty, "we draw the facts from 'the change-of-plea colloquy, the presentence investigation report ("PSR"), and the sentencing record.'" United States v. Tang, 160

F.4th 237, 240-41 (1st Cir. 2025) (quoting United States v. De La Cruz, 91 F.4th 550, 551 (1st Cir. 2024)).

From at least December 2019 through May 2021, while incarcerated at the Buckingham Correctional Center in Dillwyn, Virginia, Mao conspired with others to distribute MDMA and buprenorphine (also known as Suboxone). Mao worked with two Massachusetts-based drug traffickers, Sathtra Em and Sarath Yut, and with Kenneth Owen, a correctional officer at Buckingham, to distribute the drugs within the facility and collect the proceeds.

A federal grand jury in the District of Massachusetts returned an indictment on January 11, 2023, charging Mao with one count of conspiring to distribute and to possess with intent to distribute MDMA and buprenorphine, in violation of 21 U.S.C. § 846, and one count of conspiring to commit money laundering, in violation of 18 U.S.C. § 1956(h). Mao pled guilty to both counts on August 14, 2024, and a sentencing hearing was held on November 18, 2024.

On November 8, 2024, the Probation Office filed Mao's PSR, which calculated a base offense level of 20 under U.S.S.G. § 2D1.1 and arrived at an adjusted offense level of 26. The PSR further determined that Mao qualified as a career offender under § 4B1.1 and, after a reduction for acceptance of responsibility, calculated a total offense level of 29 and an advisory Guidelines range of 151 to 188 months' imprisonment.

The PSR correctly noted that to qualify as a career offender under the Guidelines: (1) the defendant must be "at least eighteen years old at the time the defendant committed the instant offense of conviction"; (2) the defendant's instant offense must be "a felony that is either a crime of violence or a controlled substance offense"; and (3) the defendant must have "at least two prior felony convictions of either a crime of violence or a controlled substance offense." U.S.S.G. § 4B1.1(a). A "crime of violence" is defined under the Guidelines as:

[A]ny 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 murder, voluntary manslaughter, kidnapping, aggravated assault, a forcible sex offense, robbery, arson, extortion, or the use or unlawful possession of a firearm described in 26 U.S.C. § 5845(a)

or explosive material as defined in 18 U.S.C.

§ 841(c).

U.S.S.G. § 4B1.2(a). "Subsection (1) of this definition is known as the 'force clause,'" and "the segment of subsection (2) listing specific crimes is known as the 'enumerated offenses clause.'" United States v. Frates, 896 F.3d 93, 96 (1st Cir. 2018).

The PSR concluded that Mao's two predicate Virginia felony convictions -- a 2009 conviction for use of a firearm in the commission of a robbery and a 2009 conviction for attempted murder -- qualified as crimes of violence under § 4B1.1(a). It

further found that Mao's instant conviction for conspiracy to distribute controlled substances qualified as a "controlled substance offense." Accordingly, the PSR found that the career offender enhancement should apply.

As relevant to this appeal, Mao objected to his classification as a career offender on two grounds. First, he argued that his prior conviction for use of a firearm in the commission of a robbery under Va. Code Ann. § 18.2-53.1 was not a "crime of violence" because it did not have as an element the use of force "against the person of another." Mao claimed that, under Virginia's common-law definition of robbery, a defendant could (i) use force against the robbery victim's property, as opposed to the victim's person, or (ii) threaten harm to himself rather than to the victim. Second, he argued that his instant conviction for conspiracy to commit drug trafficking was not a "controlled substance offense" because "[n]otwithstanding First Circuit precedent to the contrary," the Fourth Circuit has held that inchoate crimes such as conspiracy are not controlled substance offenses under the Guidelines.

Mao's sentencing memorandum renewed these objections, adding that his use-of-a-firearm conviction was not a crime of violence because it did not require proof of a mens rea greater than recklessness. He argued for a Guidelines range of 57 months' imprisonment.

The government's sentencing memorandum responded that Mao qualified as a career offender, contending that Mao's use-of- a-firearm conviction was a crime of violence "[b]ecause [Va. Code Ann. § 18.2-53.1] has the use of force as an element and is also a categorical match to generic robbery." The government recommended a sentence of 151 months' imprisonment, followed by four years of supervised release.

At the sentencing hearing, the district court "agree[d]

with probation and the government and the majority of the District Courts in Virginia that have considered this question that [use or display of a firearm while committing a robbery] does qualify as a crime of violence." The court reasoned that the elements of Va. Code Ann. § 18.2-53.1 require that the firearm "must be used or displayed in a threatening manner" and must "occur during the predicate offense," here robbery.

The district court also rejected Mao's claim that his conviction for conspiracy to distribute controlled substances did not qualify as a "controlled substance" offense. The court held that, notwithstanding Mao's arguments under Fourth Circuit law, "First Circuit precedence [sic] is fairly clear that . . . a conspiracy to distribute controlled substances is a controlled substance offense under the career offender guideline."

After finding that Mao qualified as a "career offender,"

the district court determined that "the guideline range without

the career offender enhancement is much too short, but . . . the career offender guideline is too long." The court imposed a sentence of 121 months' imprisonment, followed by four years of supervised release.1 II.
