LIPEZ, Circuit Judge.
Appellant David Frates pleaded guilty to one count of federal armed bank robbery, in violation of 18 U.S.C. § 2113(a) & (d). At his sentencing hearing, the district court applied the United States Sentencing Guidelines career offender enhancement, increasing Fratess guideline sentencing range to 188-235 months imprisonment. The court varied downward and sentenced Frates to 132 months imprisonment.
Frates appeals this sentence, challenging his classification as a career offender, and alternatively asking us to vacate his sentence in light of a recently enacted amendment to the Guidelines. We find no error with the district courts application of the Guidelines. Nonetheless, we exercise our discretion under United States v. Godin (Godin II ), 522 F.3d 133 (1st Cir. 2008), and United States v. Ahrendt, 560 F.3d 69 (1st Cir. 2009), to vacate Fratess sentence and remand to allow the district court to consider the United States Sentencing Commissions current policy position on who qualifies as a career offender.
I.
This case arises at a peculiar moment in the history of the Sentencing Guidelines career offender enhancement. That enhancement increases the sentencing ranges of certain defendants whose offense of conviction was either a crime of violence or a controlled substance offense, and who have at least two such prior convictions. U.S. Sentencing Guidelines Manual § 4B1.1 (2016). At the time of Fratess sentencing in July 2016, the Guidelines defined the term crime of violence as follows:
The term crime of violence means 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 use of explosives, or otherwise involves conduct that presents a serious potential risk of physical injury to another.
Id. § 4B1.2(a) (2015). Subsection (1) of this definition is known as the force clause, the segment of subsection (2) listing specific crimes is known as the enumerated offenses clause, and the segment of subsection (2) beginning with otherwise involves is known as the residual clause. See, e.g., United States v. Wurie, 867 F.3d 28, 31, 36 (1st Cir. 2017) ; United States v. Ramírez, 708 F.3d 295, 300 (1st Cir. 2013). The commentary to section 4B1.2 further specified a number of offenses that sentencing courts essentially treat[ed] ... as additional enumerated offenses. United States v. Ball, 870 F.3d 1, 5 (1st Cir. 2017) ; U.S. Sentencing Guidelines Manual § 4B1.2, cmt. n.1 (2015) (listing, for example: murder, kidnapping, aggravated assault, and robbery).
The Guidelines crime of violence definition mirrored the Armed Career Criminal Acts (ACCA) definition of violent felony. 18 U.S.C. § 924(e)(2)(B). The ACCA imposes a mandatory minimum 15-year term of imprisonment on any person convicted of being a felon in possession of a firearm who has three prior violent felony convictions. Id. §§ 922(g), 924(e)(1). Its definition of violent felony includes a force clause, an enumerated offenses clause, and a residual clause, all materially identical to the Guidelines crime of violence definition. Id. § 924(e)(2)(B).
In June 2015, the Supreme Court held that the residual clause of the ACCAs violent felony definition was unconstitutional. Johnson v. United States, --- U.S. ----, 135 S.Ct. 2551, 2563, 192 L.Ed.2d 569 (2015). It reasoned that the indeterminacy of the wide-ranging inquiry required by the residual clause both denies fair notice to defendants and invites arbitrary enforcement by judges. Id. at 2557. Sentencing judges interpreting the residual clause faced grave uncertainty about how to estimate the risk of injury involved in a crime, and also what level of risk sufficed to qualify a crime as a violent felony. Id. at 2257-58. These vagaries were more than the strictures of due process could tolerate: Invoking so shapeless a provision to condemn someone to prison for 15 years to life does not comport with the Constitutions guarantee of due process. Id. at 2560.
Not surprisingly, in the wake of Johnson, there were challenges to the constitutionality of the Guidelines crime of violence definition. Most of the circuit courts to address the issue held that section 4B1.2(a)s identically-worded residual clause was unconstitutionally vague. See United States v. Hurlburt, 835 F.3d 715 (7th Cir. 2016) ; United States v. Calabretta, 831 F.3d 128 (3d Cir. 2016) ; United States v. Pawlak, 822 F.3d 902 (6th Cir. 2016) ; United States v. Madrid, 805 F.3d 1204 (10th Cir. 2015). But see United States v. Matchett, 802 F.3d 1185 (11th Cir. 2015). In the First Circuit, the government routinely took the position that Johnsons reasoning extended to the crime of violence definition, and conceded that section 4B1.2(a)s residual clause was void. See, e.g., Ball, 870 F.3d at 3 (1st Cir. 2017) ; United States v. Thompson, 851 F.3d 129, 131 (1st Cir. 2017).
This ongoing litigation and uncertainty resulting from the Johnson decision prompted the United States Sentencing Commission to adopt an amendment eliminating the residual clause from the crime of violence definition. U.S. Sentencing Guidelines Manual supp. to app. C, Amend. 798. The amendment also moved some of the offenses listed in the commentary to section 4B1.2 into the body of section 4B1.2(a)(2). Id. Amendment 798 took effect on November 1, 2016-a few months after Fratess sentencing-and the Commission declined to make the amendment retroactive. See Wurie, 867 F.3d at 35 n.7 (noting that the Commission chose to not make Amendment 798 retroactive).
Four months after Amendment 798 took effect, the Supreme Court rejected a void-for-vagueness challenge to the crime of violence definitions residual clause. Beckles v. United States, --- U.S. ----, 137 S.Ct. 886, 890, 197 L.Ed.2d 145 (2017). Distinguishing Johnson, the Court explained that the ACCA fix[ed] the permissible sentences for criminal offenses, while the Guidelines merely guide the exercise of a courts discretion in choosing an appropriate sentence within the statutory range. Id. at 892. Since the Guidelines are discretionary, they are not amenable to a vagueness challenge, and thus § 4B1.2(a)s residual clause is not void for vagueness. Id. at 894-95.
The result in Beckles creates a quirk for defendants (1) sentenced pursuant to section 4B1.2(a)s residual clause prior to Amendment 798, and (2) whose appeals were pending when the amendment became effective. Although stricken by the Sentencing Commission, the residual clause remains valid as applied to them. Hence, they will be the last group subjected to the disfavored-yet constitutional-residual clause. This is the context in which Frates appeals his sentence.
II.
Frates asserts that neither his offense of conviction nor his prior convictions qualify as crimes of violence. As to his present conviction for federal armed bank robbery, he suggests that the crime does not fit within the force clause, and that we should remand to give the district court the opportunity to determine in the first instance whether the residual clause covers the crime. Regarding his prior convictions, he argues that his four Massachusetts unarmed robbery convictions do not count as crimes of violence under any of section 4B1.2(a)s clauses, leaving him without the two requisite crimes of violence necessary to trigger the career offender enhancement. We address these contentions in turn.
A. Fratess Offense of Conviction
It is axiomatic that in determining whether a crime fits within the force clause, we look to the elements that comprise the offense, rather than the defendants conduct in committing the crime. See, e.g., United States v. Ramos-González, 775 F.3d 483, 504 (1st Cir. 2015). This analysis involves taking a categorical approach and determining whether the elements of the defendants crime of conviction necessarily require the use, attempted use, or threatened use of physical force against another person. See, e.g., United States v. Martinez, 762 F.3d 127, 133 (1st Cir. 2014). An offense qualifies as a crime of violence under the force clause only if the least serious conduct encompassed by the elements of the offense involves the requisite physical force. United States v. Ellison, 866 F.3d 32, 35 (1st Cir. 2017).
The federal armed bank robbery statute, in relevant part, penalizes [w]hoever, by force and violence, or by intimidation, takes, or attempts to take, ... any property or money ... belonging to ... any bank ..., and who, in committing such an offense, assaults any person, or puts in jeopardy the life of any person by the use of a dangerous weapon or device. 18 U.S.C. § 2113(a) & (d). Frates argues that this offense can be committed without the use, attempted use, or threatened use of physical force. He believes that intimidation does not require force, and imagines that a robber could use poison, or withhold medication, to accomplish the crime without employing force. He further asserts that the force clause requires an intent mens rea, and that intimidation can be accomplished unintentionally.
Shortly after Frates filed his opening brief staking out these positions, we rebuffed identical arguments in Ellison, 866 F.3d at 36-38. The defendant in Ellison argued that his conviction for federal unarmed robbery did not qualify as a crime of violence under the force clause. Id. at 34. We squarely rejected his argument, concluding that section 2113(a)requires proving that a threat of bodily harm was made. Id. at 37. In doing so, we specifically spurned the threat to poison or to withhold vital medicine hypotheticals also offered here by Frates. Id. We likewise rebuffed the same mens rea argument raised by Frates, finding that section 2113(a)does have an implicit mens rea element of general intent-or knowledge-as to the actus reus of the offense. Id. at 39.
Ellison thus undermines Fratess assertion that federal armed bank robbery does not require the use, attempted use, or threatened use of force. Indeed, a conviction for federal unarmed bank robbery-at issue in Ellison-is a lesser included offense to federal armed bank robbery. See United States v. Spinney, 65 F.3d 231, 235 n.3 (1st Cir. 1995). As we are bound by this prior panel decision, e.g., Wurie, 867 F.3d at 34, we need not probe the matter further: federal armed bank robbery is a crime of violence under section 4B1.2(a)s force clause.
B. Fratess Prior Convictions
The Massachusetts statute criminalizing unarmed robbery provides:
Whoever, not being armed with a dangerous weapon, by force and violence, or by assault and putting in fear, robs, steals or takes from the person of another, or from his immediate control, money or other property which may be the subject of larceny, shall be punished by imprisonment in the state prison for life or for any term of years.
Mass. Gen. Laws ch. 265, § 19(b). The government concedes that Fratess unarmed robbery convictions do not qualify as crimes of violence under the force clause and the enumerated offenses clause. Indeed, it acknowledges our holding in Starks that Massachusetts unarmed robbery does not qualify under the ACCAs force clause, 861 F.3d at 319-20, and admits that the enumerated offense of robbery does not encompass the crime, see U.S. Sentencing Guidelines Manual § 4B1.2, cmt. n.1 (2015). Thus, we assess only whether the convictions qualify as crimes of violence under the prospectively defunct, but retrospectively applicable, residual clause.
Our precedent compels us to conclude that Massachusetts unarmed robbery is a crime of violence under the residual clause. In United States v. De Jesus, we held that the Massachusetts offense of larceny from the person qualified as a crime of violence under the residual clause. 984 F.2d 21, 22 (1st Cir. 1993). Massachusetts classifies larceny from the person as a lesser included offense of unarmed robbery. See Commonwealth v. Glowacki, 398 Mass. 507, 499 N.E.2d 290, 294 (1986) ; Commonwealth v. Sheppard, 404 Mass. 774, 537 N.E.2d 583, 585 (1989). Hence, Massachusetts unarmed robbery is necessarily a crime of violence under the residual clause.
Frates urges us to abandon this otherwise straightforward analysis and overrule De Jesus. He argues that De Jesus was based on the ordinary case method for determining whether an offense fits within the residual clause, and that Johnson rendered that methodology invalid. We disagree.
Under the ordinary case method, we assess whether the elements of the crime, in the ordinary case, (1) present a risk of physical injury similar to the risk presented by the clauses enumerated offenses and (2) [are] similar in kind to those offenses. United States v. Holloway, 630 F.3d 252, 260 (1st Cir. 2011) (quoting United States v. Giggey, 551 F.3d 27, 41-42 (1st Cir. 2008) (en banc) ); see also Ramírez, 708 F.3d at 305 (applying the ordinary case method). Although Johnson was critical of this approach, see 135 S.Ct. at 2557-58, we recently rejected the contention that the Courts criticism in the ACCA context allows us to overrule prior decisions applying the ordinary case method to section 4B1.2(a)s residual clause. In Wurie, the defendant asked us to reconsider our holding in United States v. Glover, 558 F.3d 71, 80 (1st Cir. 2009), that Massachusetts assault and battery with a dangerous weapon was a crime of violence under the residual clause. 867 F.3d at 32. We explained that Johnson did not necessarily reject[ ] the ordinary case analysis in all of its applications. Id. at 35. Rather, the Courts criticism of that methodology was only one part of its conclusion as to why the residual clause of the ACCA was unconstitutionally vague. Id. at 34. Since the Court later declined to extend Johnsons holding to the crime of violence residual clause, Beckles, 137 S.Ct. at 890, we were not persuaded that Johnsonoffers a sound reason for believing that the panel in Gloverwould change its collective mind in light of Johnson. Wurie, 867 F.3d at 35 (quoting United States v. Rodríguez, 527 F.3d 221, 225 (1st Cir. 2008) ).
Wurie thus undermines Fratess attempt to rely on Johnson to circumvent De Jesus. Instead, De Jesus remains controlling, and requires us to conclude that Massachusetts unarmed robbery is a crime of violence under the residual clause. As both Fratess offense of conviction and his prior unarmed robbery convictions were crimes of violence under the version of the Guidelines applicable at the time of his sentencing, the district court did not err in applying the career offender enhancement.
III.
Once we have concluded that a district court did not err in sentencing a defendant, it is ordinarily the end of the matter. In a narrow category of cases, however, we have discretion to vacate a correctly imposed sentence and remand to allow the sentencing court to consider the United States Sentencing Commissions revised policy positions, as demonstrated by its subsequent amendment of the Guidelines. For the reasons detailed below, this is precisely the type of case in which exercising that discretion is warranted.
A. The Godin /Ahrendt Doctrine
Our discretion to remand in such situations derives from a pair of cases involving Amendment 709 to the Guidelines. Godin II, 522 F.3d at 133 ; Ahrendt, 560 F.3d at 69. Amendment 709 restat[ed] the rules for determining when multiple crimes are counted as one for criminal history purposes. Godin II, 522 F.3d at 135 ; see also U.S. Sentencing Guidelines supp. to app. C, Amend. 709 (2007). Prior to that amendment, the First Circuit treated crimes for which the sentence was imposed on the same date as separate offenses if they were not part of a common scheme or plan, or were not consolidated for trial or sentencing. See, e.g., United States v. Godin (Godin I ), 489 F.3d 431, 434-35 (1st Cir. 2007) ; United States v. Correa, 114 F.3d 314, 317 (1st Cir. 1997). Amendment 709 rendered this approach obsolete by specifying that offenses committed without an intervening arrest are treated as a single sentence when the sentences were imposed on the same day. See U.S. Sentencing Guidelines supp. to app. C, Amend. 709 (2007); U.S. Sentencing Guidelines Manual § 4A1.2(a)(2) (2007). The amendment went into effect on November 1, 2007, after Godin and Ahrendt were sentenced but before their appeals were final. See Godin II, 522 F.3d at 134-35 ; Ahrendt, 560 F.3d at 78-79. Since the Sentencing Commission did not make Amendment 709 retroactive, the amendment would not ultimately change either defendants guideline sentencing range. See Godin II, 522 F.3d at 134-35 (noting that Amendment 709 was not retroactive).
Nonetheless, we vacated and remanded both of their sentences to give the district courts the opportunity to weigh the Sentencing Commissions revised policy as a discretionary factor in imposing sentence. Under the Commissions changed thinking, Godin and Ahrendt would have been subject to significantly lower guideline ranges. Godin had two prior burglary convictions for which she was sentenced on the same date. Id. at 134. Counting these offenses as a single sentence would have removed her from the career offender category and decreased her guideline sentencing range from 262-327 months imprisonment to 121-130 months. Id. Ahrendt had committed three offenses in the same week, and he was sentenced for those crimes on the same date. Counting his offenses as a single sentence would have decreased his guideline range from 210-262 months imprisonment to 168-210 months. See Ahrendt, 560 F.3d at 73 ; U.S. Sentencing Guidelines Manual § 5A (2005) (Sentencing Table).
Our decisions to vacate and remand in those cases were animated by two principal factors. The first involved the posture of the cases and the manner in which the Sentencing Commission chose to amend the Guidelines. In Godin II, we explained that the posture of this case is peculiar: the amendment is not applicable retroactively, but neither has the pending appeal yet resulted in a final disposition. 522 F.3d at 135. The non-finality of Godins sentence interacted with Amendment 709 to produce a procedural inequity. Amendment 709 would not alter Godins guideline range because the amendment substantively changed the Guidelines and applied only prospectively. Id. However, if the Sentencing Commission had instead issued a clarifying amendment-one that is purely expository, United States v. Cabrera-Polo, 376 F.3d 29, 32 (1st Cir. 2004) -we could have chosen to alter our own prior reading of [the] newly clarified guideline on appeal, and given Godin the benefit of the lower guideline range. Godin II, 522 F.3d at 135. Thus, without a remand to allow the district court to consider the Commissions revised policy, Godin would have been irremediably worse off because the Commission went further in her direction by substantively revising the offending provision of the Guidelines instead of issuing a mere clarification. Id. at 136.
The second factor that led us to vacate and remand in Godin and Ahrendt was the discretionary nature of the federal sentencing regime after United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). Under federal sentencing procedures post-Booker, district courts begin by calculating a defendants guideline sentencing range. See, e.g., Molina-Martinez v. United States, --- U.S. ----, 136 S.Ct. 1338, 1345, 194 L.Ed.2d 444 (2016). This range is merely advisory. See Booker, 543 U.S. at 245, 125 S.Ct. 738. Courts then exercise their discretion to select a sentence-either inside or outside of the advisory guideline range-that is sufficient, but not greater than necessary to fulfill certain sentencing objectives. 18 U.S.C. § 3553(a). Godin and Ahrendt recognized that the Commissions current policy positions may be relevant at this second, discretionary, step of a district courts sentencing procedures, even when a non-retroactive amendment prevents the district court from altering the advisory guideline range calculated at the first step. See Godin II, 522 F.3d at 136 ; Ahrendt, 560 F.3d at 79.
Three more recent cases provide guidance on when we will choose to exercise our discretion under the Godin/ Ahrendt doctrine. The defendant in United States v. Matos, 611 F.3d 31 (1st Cir. 2010), asked us to vacate his sentence and remand to allow the district court to consider Amendment 709. Distinguishing Godin II and Ahrendt, we explained that it was evident in those cases that if the Guidelines as amended ... had been in effect at the time of the defendants sentencing, the defendant would have been subjected to a lower sentencing range. Id. at 39. However, it was far from clear that Amendment 709 would have had any effect on Matoss sentence. Id. The district court would have had to engage in fact-finding to determine whether the Amendment applie[d]. Id. Given the complexity of the district courts task on remand, we conclude[d] that Godin and Ahrendt [did] not advocate in favor of remanding for resentencing. Id. at 39-40.
We recently applied this reasoning from Matos in a case involving Amendment 798. In Wurie, we explained that it was unclear whether the defendant would have benefitted from the intervening amendment. 867 F.3d at 36. On remand, the district court would have had to consider whether at least two of Wuries prior offenses ... qualify as crimes of violence under the force clause. Id. This analysis would have been much more complicated than the simple mechanistic change involved in Godin II and Ahrendt. Id. at 36-37. We accordingly declined to vacate the defendants sentence and remand for resentencing.
Lastly, we ordinarily will not use our discretion under the Godin/ Ahrendt doctrine when the district court was aware of the proposed amendment at the time of the initial sentencing. See United States v. Adams, 640 F.3d 41, 43 (1st Cir. 2011). The courts awareness of the amendment extinguishes the doubt triggering our concern in Godin and Ahrendt that the district court would reconsider the sentences in light of the now-revised thinking of the Commission. Id.
Godin II and Ahrendt thus establish a narrow doctrine that gives us discretion to vacate a defendants sentence and remand when: (i) the Sentencing Commission adopts a substantive, non-retroactive amendment to the Guidelines; (ii) the amendment is adopted before the defendants sentence becomes final on appeal; and (iii) the amendment would have lowered the defendants guideline range if it had been in effect at the initial sentencing. However, we will ordinarily not exercise our discretion under Godin/ Ahrendt when the district courts analysis on remand would be complex, or when the district court was aware of the amendment during the initial sentencing.
If we do remand a case pursuant to the Godin/ Ahrendt doctrine, the district court is prohibited from recalculating the defendants guideline range in light of the intervening amendment, lest it circumvent the Sentencing Commissions non-retroactivity determination. It may, however, consider the Commissions revised policy position in exercising its discretion to select an appropriate sentence for the defendant.
B. Vacating Fratess Sentence and Remanding for Resentencing
The facts of this case squarely implicate our Godin/ Ahrendt doctrine, and counsel in favor of exercising our discretion to vacate Fratess sentence and remand to the district court. Amendment 798 is a substantive, non-retroactive amendment that the Sentencing Commission enacted while Fratess appeal was pending. If the amendment had been in effect at the time of Fratess sentencing, his guideline range would have decreased from 188-235 months imprisonment to 92-115 months. Indeed, the government concedes that Fratess prior convictions for Massachusetts unarmed robbery would not qualify as crimes of violence under Amendment 798.
Given the governments concession, the sentencing process on remand will be mechanistic, not complex. Wurie, 867 F.3d at 37. The district court will need to consider only whether the Sentencing Commissions current policy about who qualifies as a career offender affects its discretionary choice of sentence. Finally, there is no indication that the district court was aware of Amendment 798 at the time of sentencing.
The government advances three primary reasons why we should nonetheless decline to vacate Fratess sentence and remand for resentencing. All three are unpersuasive. First, the government argues that a line from the Supreme Courts decision in Dillon v. United States, 560 U.S. 817, 130 S.Ct. 2683, 177 L.Ed.2d 271 (2010), undermines the Godin/ Ahrendt doctrine. Dillon involved the question of whether a provision of the Guidelines that limited a courts discretion in sentence modification proceedings remained mandatory-rather than advisory-after Booker. 560 U.S. at 819-822, 130 S.Ct. 2683. In holding that the provision was mandatory, the Court sought to establish that other provisions of the Guidelines likewise remained binding post-Booker. Id. at 830, 130 S.Ct. 2683. It thus observed that [n]o one disputes that the Commissions retroactivity determinations ... are binding. Id.
The Godin/ Ahrendt doctrine is entirely consistent with the Supreme Courts observation that the Sentencing Commissions retroactivity determinations are binding. Both Godin II and Ahrendt acknowledge that the Commissions pronouncement that Amendment 709 was non-retroactive bound the court. Godin II, 522 F.3d at 136 (The original guideline range ... remains applicable, because the amendment was substantive and non-retroactive.); Ahrendt, 560 F.3d at 79 (Because Amendment 709 is non-retroactive, ... Ahrendt is not entitled to the benefit of [the] amendment....). Indeed, the Godin/ Ahrendt doctrine necessarily presupposes that the Commissions retroactivity determinations are binding. It only allows district courts to consider the Sentencing Commissions revised policies as a discretionary factor in resentencing defendants.
Second, the government contends that vacating and remanding in this case will effectively open the floodgates for defendants challenging their sentences in light of Johnson. This position is vastly overstated. As we detailed above, the Godin/ Ahrendt doctrine applies only to a narrow category of cases involving certain non-retroactive amendments that are adopted before a defendants sentence becomes final on appeal. Our holding here is thus potentially relevant to defendants sentenced pursuant to section 4B1.2(a)s residual clause only if their sentences were not yet final when Amendment 798 went into effect in November 2017. We fail to see how-as the government seems to suggest-this case would apply more broadly to defendants challenging their sentences based on Johnsons invalidation of the ACCAs residual clause.
Third, the government contends that the district courts decision to vary downward from Fratess guideline sentencing range makes remanding his case for resentencing unnecessary. Though perhaps not irrelevant, a district courts decision to depart from a defendants guideline range will not ordinarily be a significant factor in determining whether to remand under Godin/ Ahrendt. Ahrendt, 560 F.3d at 80 (reasoning that the amount an amendment reduces a defendants guideline range is not dispositive in deciding whether to remand). A downward variance does not necessarily alter our judgment that a different result might well be reached on remand, Adams, 640 F.3d at 43, as the Sentencing Commissions revised policy may lead a district court to vary further from a defendants guideline range. Indeed, the guideline range anchor[s] ... the district courts discretion, such that even when the sentencing judge sees a reason to vary from the Guidelines ... the Guidelines are in a real sense [still] the basis for the sentence. Molina-Martinez, 136 S.Ct. at 1346 (emphasis omitted) (quoting Peugh v. United States, 569 U.S. 530, 542, 549, 133 S.Ct. 2072, 186 L.Ed.2d 84 (2013) ). The knowledge that the Sentencing Commission would choose a different anchor thus remains a relevant discretionary factor for district courts to consider even where they initially varied downward.
This case provides a prime example of this principle. The district court varied downward based on Fratess history of substance abuse and mental health issues, and imposed a sentence of 132 months imprisonment. Under the Sentencing Commissions current thinking, that sentence would constitute an upward variance of 17 months. The district court may well view this fact as reason to vary even more significantly from Fratess guideline range.
IV.
For these reasons, we think it prudent to allow the [district] court the opportunity to consider the Sentencing Commissions updated views. Ahrendt, 560 F.3d at 80. We therefore vacate Fratess sentence and remand for resentencing consistent with this opinion. On remand, the courts initial calculation of Fratess guideline range remains in effect. The court is under no obligation to modify Fratess sentence if, in its discretion, it does not feel that modification is warranted.
So ordered.
We employ a modified categorical approach when the statute sets forth alternative elements of a crime, some of which are broader than the crime of violence definition. See Descamps v. United States, 570 U.S. 254, 257, 133 S.Ct. 2276, 186 L.Ed.2d 438 (2013) ; Ramos-González, 775 F.3d at 505. This approach allows us to consult a limited set of judicial records to determine which set of elements provided the basis for the defendants conviction. Ramos-Gonzalez, 775 F.3d at 505 ; see also Shepard v. United States, 544 U.S. 13, 26, 125 S.Ct. 1254, 161 L.Ed.2d 205 (2005) (listing the charging document, plea agreement, plea transcript, and comparable judicial record[s] as permissible documents). The parties agree that we should employ the categorical approach, and we accept their position without deciding the issue. See United States v. Starks, 861 F.3d 306, 317 (1st Cir. 2017).
The district court also concluded that Fratess prior conviction for Massachusetts breaking and entering was a crime of violence. Frates did not appeal this decision.
More specifically, Godin was sentenced in April 2006, we first decided her appeal in June 2007, and we adjudicated her petition for rehearing in April 2008. Godin II, 522 F.3d at 133-34. Ahrendt was sentenced in January 2006 and we resolved his appeal in March 2009. Ahrendt, 560 F.3d at 73.
The government specifically conceded that Massachusetts unarmed robbery would not qualify as crimes of violence under section 4B1.2(a)s force clause or under its enumerated crime of robbery.
