Financial Vulnerability and Fraud: A Direct Nexus, Not Inability to Detect, Governs the Vulnerable-Victim Enhancement

Case: United States v. Koch, consolidated with the appeals of Megan Hess
Court: United States Court of Appeals for the Tenth Circuit
Date: October 27, 2026
Opinion: Judge McHugh, joined by Judges Ebel and Kelly

1. Introduction

This published decision clarifies when financial hardship makes a fraud victim unusually vulnerable under U.S.S.G. § 3A1.1(b). The Tenth Circuit held that individualized evidence connecting financial vulnerability to the acquisition of victims’ business can support the enhancement, even without proof that those victims were less capable of detecting or stopping the fraud. The necessary connection exists when defendants exploit particular victims’ financial circumstances to obtain access essential to their scheme.

The case arose from a funeral-home operation in which Megan Hess and her mother, Shirley Koch, fraudulently obtained human remains, sold bodies and body parts, and misrepresented the services provided to bereaved families. Following an earlier appellate reversal of sentencing errors, the district court imposed the same prison terms on resentencing: 240 months for Hess and 180 months for Koch.

The consolidated appeals presented three principal questions:

  • Whether individualized findings supported the additional enhancement for an offense involving a large number of vulnerable victims.
  • Whether the district court plainly erred in its treatment of Hess’s post-sentencing rehabilitation.
  • Whether Koch’s substantial upward variance was substantively unreasonable.

The court affirmed both sentences. Its principal contribution is a clarification of existing vulnerability doctrine, not a categorical declaration that poverty, age, or bereavement automatically establishes unusual susceptibility to fraud.

2. Background and Procedural History

The fraudulent operation

Hess operated Sunset Mesa Funeral Directors and a nonprofit known as Donor Services. Although Donor Services ostensibly assisted people unable to afford funeral services, its primary purpose was to market human remains for scientific, medical, and educational uses. Koch worked at the funeral home, participated in dealings with families, and helped dismember and prepare remains for sale.

The defendants sometimes obtained limited donation authorizations through false representations and then exceeded those authorizations. In other instances, they sold remains despite receiving no permission or an express refusal. Families frequently paid for cremations that never occurred and received ashes falsely represented as their relatives’ remains.

The operation’s records documented transactions involving 811 individuals. Investigators confirmed that at least 222 bodies had been stolen and concluded that another 338 almost certainly had been. Only 42 bodies were identified as having been obtained through informed consent. The defendants also misrepresented the legitimacy of donations to purchasers and, in some instances, falsified disease-test results.

The illicit sales subsidized unusually inexpensive cremation prices. That pricing strategy became central to the resentencing analysis: low advertised prices and offers of free services drew financially distressed families to the funeral home, supplying bodies for the fraudulent operation.

Guilty pleas and the first appeal

Each defendant pleaded guilty to one count of mail fraud and aiding and abetting. The remaining charges were dismissed. Koch’s plea agreement required the government to recommend a sentence within an anticipated advisory range of 63 to 78 months.

At the original sentencing, the district court applied both components of the vulnerable-victim adjustment:

  1. A two-level increase under § 3A1.1(b)(1), requiring knowledge or constructive knowledge of a victim’s vulnerability.
  2. An additional two-level increase under § 3A1.1(b)(2), applicable when the offense involves a large number of vulnerable victims.

The court initially treated deceased persons and their grieving family members as two large groups of vulnerable victims. In United States v. Hess, 106 F.4th 1011 (10th Cir. 2024), the Tenth Circuit rejected that reasoning. Persons already deceased when the fraud occurred could not qualify on that basis, and grief alone did not establish the required connection between an individual victim’s vulnerability and the fraud.

The earlier appeal also identified errors involving loss calculations and Koch’s sophisticated-means enhancement. The case returned to the district court for resentencing, including an opportunity to make particularized vulnerability findings.

Resentencing

On remand, the government accepted a twelve-level loss enhancement rather than the original fourteen-level increase. It also presented additional victim statements and expert testimony from Dr. Doug Shadel concerning the relationship between multiple stressful life events and susceptibility to fraud.

The district court identified twenty-one individual victims whose circumstances, it concluded, facilitated the scheme. It again imposed the large-number enhancement and then varied upward from the recalculated advisory ranges:

Defendant Resentencing advisory range Sentence imposed
Megan Hess 121–151 months 240 months, the statutory maximum
Shirley Koch 78–97 months 180 months

Both defendants appealed the resentencing judgments and subsequent judgments incorporating restitution. The appellate issues addressed in the opinion concerned the sentencing enhancement, rehabilitation evidence, and Koch’s sentence length.

3. Summary of the Opinion

  • Individualized financial vulnerability can qualify. The record established that the defendants exploited particular families’ financial constraints through inexpensive or free cremation offers, thereby obtaining access to bodies they fraudulently sold.
  • Reduced ability to detect fraud is not indispensable. The governing inquiry is whether vulnerability enabled or facilitated the particular offense, not exclusively whether it impaired detection or resistance.
  • Fifteen qualifying victims were sufficient. The court upheld vulnerability findings for fifteen victims and held that this satisfied the large-number requirement in this mail-fraud case. It did not establish the minimum number required in every fraud case.
  • Personal contact with every victim is unnecessary. Section 3A1.1(b)(2) reaches victims of relevant conduct attributable to the defendant, including conduct she aided and abetted.
  • Hess did not establish plain error concerning rehabilitation. Assuming an error occurred, it was not clearly established under existing law, and she did not show a reasonable probability of a different sentence.
  • Koch’s upward variance was substantively reasonable. The district court permissibly concluded that the exceptional harm, prolonged misconduct, and lack of remorse outweighed mitigating considerations.

4. Analysis: Legal Reasoning

A. The enhancement requires offense-specific susceptibility

Section 3A1.1(b)(1) applies when a defendant knew or should have known that a victim was vulnerable. If that provision applies and the offense involved a large number of vulnerable victims, § 3A1.1(b)(2) adds another two levels.

The Guidelines commentary defines a vulnerable victim as someone victimized by the offense or relevant conduct who is unusually vulnerable because of age, physical or mental condition, or another characteristic making the person particularly susceptible to the criminal conduct. Neither defendant challenged the initial two-level enhancement in this appeal. The dispute concerned the additional increase.

The central limitation is relational: a person must be unusually susceptible to the particular offense, not merely vulnerable in ordinary life. Poverty, grief, illness, and age may be relevant, but their existence alone does not complete the analysis. The sentencing court must explain how the characteristic enabled or facilitated the crime.

B. The nexus can arise when defendants obtain access to the property involved

Hess argued that the victims were no more vulnerable than anyone else because no ordinary customer could have discovered what happened once the funeral home obtained unsupervised possession of the bodies. On her account, the enhancement required proof that vulnerable victims were less able than others to detect or thwart the scheme.

The court rejected that proposed restriction. Nothing in the Guidelines commentary makes impaired fraud-detection ability an essential element. Its example of an ineffective cancer cure demonstrates that vulnerability can consist of a condition that makes a fraudulent offer especially appealing or relevant.

The defendants’ access to the bodies was not treated as a fixed circumstance divorced from the fraud. Rather, obtaining that access was a necessary part of the operation. Particular victims’ inability to afford conventional services made offers of inexpensive or free cremations unusually effective in inducing them to entrust remains to the defendants.

This reasoning distinguishes a vulnerability that merely creates an opportunity to meet a victim from one that directly helps procure the subject matter of the fraud. The defendants did not simply encounter financially distressed people and later commit an unrelated offense. Their promises addressed those people’s immediate financial needs and secured the bodies the scheme required.

C. Particularized findings do not become categorical merely because victims share a characteristic

The district court’s original error was to assume that grief made all bereaved customers unusually susceptible. On remand, it relied instead on individual accounts describing financial pressures, caregiving burdens, illness, isolation, and the reasons particular families selected Sunset Mesa.

The appellate court highlighted several concrete connections:

  • J.D. could not afford immediate cremation costs. Koch offered free cremation in exchange for a supposed brain donation for Alzheimer’s research. The grandfather’s entire body was instead sold.
  • M.C.-P. had little income and serious health problems. The defendants persuaded her to abandon planned embalming for cheaper cremation, obtaining access to her grandmother’s body for fraudulent sale.
  • K.B. faced financial and caregiving pressures and received a purported special price because her husband was a veteran.
  • N.H. was managing debt and had to borrow funeral money. Low prices and assurances of careful treatment induced her choice.
  • T.F. faced debt after her husband’s prolonged cancer treatment and selected Sunset Mesa over a local provider because of price.

Comparable findings supported the treatment of M.B., D.Mc., D.W., A.S.J., and R.B. as financially vulnerable victims. Together with five victims whose terminal-illness or hospice-related vulnerability Hess did not contest, these findings supported fifteen qualifying victims.

The court did not affirm every one of the district court’s twenty-one findings. It found fifteen sufficient and left the remaining findings unresolved. Consequently, the decision should not be cited as approving every form of financial or emotional vulnerability described in the resentencing record.

The distinction between an impermissible class assumption and permissible shared evidence is important. Multiple victims may have the same vulnerability. What matters is whether evidence connects that vulnerability to each victim’s participation in the particular transaction, rather than substituting group membership for proof.

D. “A large number” depends on the offense context

The Guidelines do not supply a universal numerical definition for § 3A1.1(b)(2). The court therefore considered the nature of the offense and analogous Guidelines provisions.

Fraud provisions contain victim-related thresholds of five, ten, and twenty-five. Earlier circuit authority had also upheld the large-number enhancement in a fraud case involving sixteen particularly vulnerable victims. Against that background, fifteen qualifying victims were enough here.

The holding is deliberately limited. The court did not decide whether five or ten vulnerable victims would suffice in a fraud case, and it did not transform an earlier involuntary-servitude decision into a universal ten-victim rule.

E. Koch’s responsibility extended beyond customers she personally met

Koch argued that she lacked meaningful contact with most identified victims and therefore could not have exploited their vulnerabilities. The court answered through the Guidelines’ relevant-conduct provisions.

The commentary to § 3A1.1 includes victims of conduct attributable to a defendant under § 1B1.3. Section 1B1.3(a)(1)(A), in turn, includes acts committed, aided, abetted, counseled, induced, procured, or willfully caused by the defendant in connection with the offense.

The distinction between the two enhancement provisions was decisive:

  • Section 3A1.1(b)(1) expressly requires that the defendant knew or should have known of a victim’s vulnerability.
  • Section 3A1.1(b)(2) adds no separate requirement that the defendant know the vulnerabilities of every victim included in the large-number calculation.

Once the first enhancement applies, the additional enhancement is offense-specific and reaches qualifying victims of attributable relevant conduct. Koch’s aiding-and-abetting responsibility therefore prevented her from limiting the count to people with whom she personally dealt.

This is not unlimited attribution based on association alone. The relevant victims must still fall within conduct for which the Guidelines make the defendant accountable.

F. The government’s recommendation did not control the legal calculation

Consistent with its understanding of Koch’s plea agreement, the government recommended against the additional enhancement and requested 78 months. That position did not bind the sentencing court on a legal question.

The government could also defend the resulting judgment on appeal despite its position below. The court distinguished an appellee’s ability to support an existing judgment from an appellant’s attempt to secure reversal through an unpreserved argument.

Koch suggested that the government’s presentation of evidence might have breached the plea agreement, but she did not develop that contention. The court deemed it waived. Accordingly, the opinion does not resolve the substantive plea-breach question or establish that every form of government advocacy inconsistent with a sentencing promise is permissible.

G. Rehabilitation evidence did not establish reversible plain error

Hess submitted evidence of educational work, courses, inmate assistance, supportive letters, and other productive prison activities. The district court described her conduct as commendable but also expected, and noted the availability of good-time credit.

Because Hess did not object at resentencing, she had to satisfy plain-error review. The appellate court assumed, without deciding, that the district court erred, but rejected her claim on two independent grounds.

First, any error was not obvious under settled law. The Supreme Court’s rehabilitation precedent permits consideration of post-sentencing rehabilitation and recognizes that it can support a lower sentence. It does not require a reduction whenever such evidence exists. Nor did it clearly prohibit considering good-time credit when deciding how much weight to give the evidence.

Second, Hess failed to establish prejudice. The district court repeatedly stated that the nature and consequences of the offense outweighed mitigating circumstances. Its concerns included her continued minimization of the victims’ injuries and lack of remorse. The appellate court found no reasonable probability that a different treatment of rehabilitation would have produced a shorter sentence.

The ruling is therefore narrower than an unqualified endorsement of the district court’s approach. It does not authorize a categorical refusal to consider rehabilitation or declare that constructive prison activities are irrelevant.

H. Koch’s substantial variance remained within permissible sentencing discretion

Koch emphasized her age, serious health problems, limited criminal history, and lesser role relative to Hess. She argued that a fifteen-year sentence was effectively a life sentence and disproportionate to what she characterized as a white-collar fraud.

The court concluded that the district judge had considered these matters rather than ignored them. The judge also identified circumstances inadequately captured by the ordinary fraud calculation: prolonged desecration and unauthorized sale of remains, extraordinary emotional injury, betrayal of trust, and virtually no remorse. Koch’s prior fraud-related felony, although not producing criminal-history points, also informed the court’s evaluation of her history.

The district court recognized comparative culpability by sentencing Koch to five years less than Hess. The appellate court did not independently rebalance these considerations. It asked whether the district court’s explained judgment fell outside the bounds of permissible choice and held that it did not.

5. Analysis: Precedents Cited and Their Influence

A. The prior appeal and the vulnerability requirement

United States v. Hess, 106 F.4th 1011 (10th Cir. 2024)

The earlier appeal supplied the governing remand instructions: deceased persons could not qualify as vulnerable victims on the theory originally advanced, and bereavement could not substitute for proof of a nexus to the fraud. The present opinion treats the new evidence as curing that deficiency. It does not abandon the earlier requirement; it explains how financial inducements and individualized circumstances satisfied it.

United States v. Proffit, 304 F.3d 1001 (10th Cir. 2002)

A rancher’s cancer diagnosis prompted him to offer his ranch for sale, allowing the defendant to approach him. The eventual fraud, however, concerned a purported cattle-futures investment. The diagnosis explained the meeting but not the victim’s susceptibility to that investment, so the enhancement failed. Crucially, the court suggested that fraudulently obtaining the ranch itself could produce a different result. Here, financial hardship directly induced the transactions supplying bodies to the scheme, making the connection materially closer.

United States v. Tissnolthtos, 115 F.3d 759 (10th Cir. 1997), and United States v. Drapeau, 110 F.3d 618 (8th Cir. 1997)

The former rejected reliance on a seventy-one-year-old assault victim’s age without individualized findings. It contrasted the exceptionally strong inference of vulnerability associated with a one-year-old assault victim, as recognized in the latter. Together, these decisions explain why class characteristics sometimes permit obvious inferences but ordinarily require evidence of actual, offense-related susceptibility.

United States v. Fosher, 124 F.3d 52 (1st Cir. 1997)

Hess invoked its language asking whether a victim was less likely to detect or thwart the crime. The Tenth Circuit declined to adopt that formulation as a necessary limitation. Its own precedents and the Guidelines commentary instead focus on whether vulnerability enabled or facilitated the particular offense.

United States v. Brunson, 54 F.3d 673 (10th Cir. 1995)

This case rejected an enhancement based on a defendant’s belief that foreign companies were easier to deceive and the fact that the fraud succeeded. Neither subjective assumptions nor completed victimization established objective unusual vulnerability. The present opinion distinguished those unsupported premises from documented financial constraints directly exploited through the defendants’ pricing strategy.

United States v. Creech, 913 F.2d 780 (10th Cir. 1990)

The court rejected a presumption that newlyweds were unusually vulnerable to threats against their spouses: longer-married people could be equally distressed. This precedent reinforced the prohibition against unsupported class assumptions, while leaving room for evidence-based findings about particular victims.

United States v. Scott, 529 F.3d 1290 (10th Cir. 2008), and United States v. Castaneda, 239 F.3d 978 (9th Cir. 2001)

The opinion drew from these authorities the rationale that exploiting a particular victim’s vulnerability can make conduct more blameworthy and deserving of greater punishment. The former also supplied an example involving exploitation of a minor’s small stature and unusual naivety in trafficking. This rationale supported the enhancement here but did not replace the need to prove susceptibility and a nexus.

United States v. Caballero, 277 F.3d 1235 (10th Cir. 2002)

This immigration-fraud decision upheld findings based on exploited language barriers, unfamiliarity with United States law, cultural background, and immigration status. It supported two conclusions: shared characteristics do not invalidate otherwise individualized findings, and sixteen particularly vulnerable victims can satisfy the large-number requirement in a fraud case. The present court relied on that numerical comparison in accepting fifteen.

B. The numerical requirement and relevant conduct

United States v. Kaufman, 546 F.3d 1242 (10th Cir. 2008)

In a prosecution involving exploitation of mentally ill residents of an unlicensed group home, the court looked to involuntary-servitude Guidelines to interpret “a large number.” It held that ten victims were a large number in the forced-labor and involuntary-servitude context. Its influence here was methodological: examine the offense context, rather than apply a universal numerical threshold.

United States v. Anderson, 349 F.3d 568 (8th Cir. 2003)

This authority appeared through the discussion in the preceding precedent, acknowledging that the phrase “large number” was largely uninterpreted. It provided background for the contextual inquiry, not an independently controlling threshold.

United States v. Boll, 3 F.4th 1099 (8th Cir. 2021)

Koch relied on its contextual approach, but the decision expressly included the offense of conviction and all relevant conduct. The Tenth Circuit explained that “context” referred to offenses of like kind, not merely the defendant’s personal customer interactions. It therefore did not support excluding victims of conduct Koch aided and abetted.

C. Legal concessions, appellate arguments, and waiver

United States v. Ronquillo, 94 F.4th 1169 (10th Cir. 2024)

The court independently interpreted a search warrant despite the government’s contrary concession below. Its principle—that parties’ stipulations on legal questions do not bind courts—supported the district court’s independent Guidelines calculation here.

Richison v. Ernest Grp., 634 F.3d 1123 (10th Cir. 2011)

This decision distinguished arguments supporting affirmance from arguments seeking reversal. It supported allowing the government, as appellee, to defend a judgment on a record-supported ground notwithstanding its earlier legal position.

LaFevers v. Gibson, 182 F.3d 705 (10th Cir. 1999)

The opinion applied its rule that perfunctory references without developed argument do not preserve an appellate issue. Koch’s suggestion of a plea-agreement breach consequently received no merits determination.

D. Guidelines interpretation and standards of review

United States v. Tony, 121 F.4th 56 (10th Cir. 2024)

This decision directed attention to the Sentencing Commission’s intent as expressed in the Guidelines and their commentary. Commentary governs unless constitutionally or statutorily invalid, plainly erroneous, or inconsistent with the provision interpreted. That framework supported reliance on the cancer-cure example and relevant-conduct commentary.

United States v. Sumka, 81 F.4th 1153 (10th Cir. 2023)

This authority distinguishes clear-error review of vulnerability findings from de novo review of legal interpretation or legal sufficiency. As in that case, the court declined to resolve the parties’ disagreement about the precise standard because the enhancement survived either approach.

United States v. Rocha, 145 F.4th 1247 (10th Cir. 2025)

This decision supplied the general sentencing-review framework: legal conclusions receive de novo review, factual findings receive clear-error review, and the ultimate sentencing decision receives deferential abuse-of-discretion review. It also established that outside-Guidelines sentences are not presumptively unreasonable and illustrated an upward variance justified by extraordinary recklessness inadequately captured by the Guidelines.

United States v. Peña, 963 F.3d 1016 (10th Cir. 2020), and United States v. Holt, 161 F.4th 1253 (10th Cir. 2025)

These decisions describe the substantial deference owed to sentencing courts. A sentence warrants reversal when arbitrary, capricious, whimsical, manifestly unreasonable, or beyond permissible choice—not simply because appellate judges might have selected a different term.

E. Rehabilitation and plain error

Pepper v. United States, 562 U.S. 476 (2011)

The Supreme Court permitted consideration of post-sentencing rehabilitation at resentencing and recognized that it may justify a downward variance. It rejected a categorical prohibition and explained that good-time credit and sentence reductions serve different penological interests. But it expressly declined to require a reduction upon every showing of rehabilitation. That distinction prevented Hess from establishing an obvious violation on this record.

United States v. Kee, 129 F.4th 1249 (10th Cir. 2025)

This authority supplied the four-part plain-error test: error, plainness, effect on substantial rights, and serious impairment of judicial fairness, integrity, or public reputation. Hess bore the burden because she had not objected during resentencing.

United States v. Booker, 63 F.4th 1254 (10th Cir. 2023)

This Tenth Circuit decision supplied the requirements that an error be obvious under settled law and that prejudice involve a reasonable probability of a different outcome. The opinion applied both principles against Hess. This citation is to the 2023 circuit decision, not the Supreme Court’s separate sentencing decision bearing the same name.

F. Substantial upward variances

United States v. Doty, 150 F.4th 1351 (10th Cir. 2025)

An increase from a 33–41-month range to 96 months was upheld because the offense was atypical and extraordinarily harmful. It illustrated that severe harm omitted from an ordinary Guidelines calculation may justify a major variance.

United States v. Lawless, 979 F.3d 849 (10th Cir. 2020)

The court upheld a variance from 60 to 144 months for unusually serious arson. It also cautioned against appellate reweighing of § 3553(a) considerations. Both principles directly supported rejection of Koch’s substantive challenge.

United States v. Walker, 74 F.4th 1163 (10th Cir. 2023)

This decision upheld a sentence of 300 months against an 84–105-month range, relying partly on the severity of the victim’s mental and physical injuries. It reinforced the relevance of exceptional nonfinancial harm.

United States v. Vazquez-Garcia, 130 F.4th 891 (10th Cir. 2025)

A variance from 24–30 months to 48 months was upheld in part because the defendant showed no remorse for child sexual abuse. The opinion cited it to confirm that lack of remorse can contribute to an upward-variance justification.

6. Potential Impact

Financial exploitation beyond cognitive impairment

The decision makes clear that unusual vulnerability need not involve diminished intelligence, confusion, or inability to investigate. Financial constraints may make a particular fraudulent offer unusually compelling. Future applications could therefore focus on how defendants tailored inducements to documented needs, rather than exclusively on victims’ capacity to recognize deception.

Acquisition-stage evidence will matter

The opinion directs attention to how defendants obtained access, authority, or possession. A scheme that becomes difficult for anyone to detect after a transfer may still exploit vulnerability in securing that transfer. Victim statements explaining provider selection, price sensitivity, and responses to individualized promises can therefore be important sentencing evidence.

Continued protection against categorical enhancements

The decision preserves meaningful limits. A prosecutor cannot establish the enhancement simply by identifying poor, elderly, ill, or grieving victims. The record must connect their circumstances to unusual susceptibility to the particular offense. Successful victimization and a defendant’s unsupported assumptions remain insufficient.

Broader attribution within accountable conduct

Participants who aid and abet a scheme cannot necessarily narrow the vulnerable-victim count to their personal contacts. Nevertheless, courts must identify conduct attributable under the Guidelines and confirm that the initial knowledge-based enhancement applies.

Limited numerical and rehabilitation holdings

Fifteen vulnerable victims suffice in this fraud setting, but the minimum remains unresolved. Similarly, the rehabilitation ruling principally demonstrates the importance of preserving objections and proving prejudice; it does not settle every question about the appropriate weight of rehabilitation evidence.

Exceptional harm can sustain major variances

The affirmance confirms that a fraud guideline may inadequately reflect profound nonfinancial injuries. A substantial variance can survive where the district court explains those injuries, considers mitigation, and distinguishes defendants’ culpability. The decision does not make similar variances automatic or insulate them from review.

7. Complex Concepts Simplified

Vulnerable victim
A person whose particular circumstances make the specific crime unusually effective against them—not simply anyone facing hardship.
Nexus
The connection between the vulnerability and the offense. Here, financial distress made low-cost cremation promises effective in securing bodies for fraudulent sale.
Particularized findings
Evidence-based explanations about individual victims, rather than assumptions about everyone in a broad group.
Relevant conduct
Conduct counted at sentencing under the Guidelines, including acts the defendant personally committed or aided and abetted.
Scienter
A required mental state. The initial enhancement requires actual or constructive knowledge of vulnerability; the additional large-number provision adds no separate knowledge requirement for every counted victim.
Upward variance
A sentence above the advisory Guidelines range based on statutory sentencing considerations, rather than a change to the Guidelines calculation itself.
Plain error
A demanding review standard for an unpreserved objection. Showing a possible mistake is insufficient; the defendant must also establish obviousness, prejudice, and the required institutional harm.
Substantive reasonableness
Whether the sentence’s length is permissible considering the circumstances and statutory sentencing factors, with substantial deference to the sentencing judge.

8. Conclusion

The opinion’s central rule is that direct exploitation of individualized vulnerability—not necessarily reduced ability to detect fraud—supports the vulnerable-victim enhancement. Documented financial pressures helped the defendants obtain the bodies essential to their scheme, and fifteen qualifying victims satisfied the large-number requirement here.

The decision also confirms relevant-conduct attribution for aiders and abettors, the demanding nature of unpreserved rehabilitation challenges, and the discretion to impose substantial upward variances for extraordinary harm. Its limits remain important: poverty is not categorically vulnerability, fifteen is not a universal minimum, and rehabilitation remains a permissible and potentially significant resentencing consideration.
