Cash-to-Drug Conversion May Track Seized-Drug Ratios and Purity; Firearm Enhancement Burdens and Rule 32 Dispute Requirements Reaffirmed in Sixth Circuit Drug-Conspiracy Sentencing

3.1 Precedents Cited

A. Appellate sentencing review framework

• Gall v. United States established abuse-of-discretion review for sentencing reasonableness and identified hallmark procedural errors (miscalculating Guidelines, treating them as mandatory, relying on clearly erroneous facts, inadequate explanation).
• United States v. Morgan (procedural vs. substantive reasonableness) and United States v. Brooks (de novo review of Guidelines interpretation; clear-error review of factual findings) supplied the Sixth Circuit’s review architecture.

B. Drug quantity approximation and cash-to-drug conversion

• United States v. McReynolds framed drug-quantity review as clear-error review of factual determinations.
• United States v. Crowe underscored the Guidelines’ quantity-driven sentencing severity under §2D1.1.
• United States v. Sandridge and United States v. Johnson supplied two key constraints on approximation: evidentiary reliability (a “minimal level of reliability”) and the admonition to “err on the side of caution” when uncertainty exists.
• United States v. Russell and United States v. Warman supported the proposition that seized funds may be converted into equivalent drug weight, requiring proof by a preponderance as to both attribution to drug activity and the conversion ratio.
• United States v. Mahaffey (quoting United States v. Brannon) articulated that an approximation is not clearly erroneous if supported by “competent evidence in the record.”
• United States v. Gilliam-French reinforced that courts are not required to use controlled-buy samples as representative of the whole trafficking enterprise.
• United States v. Murillo-Almarez exemplified an “ascertainable methodology” approach (divide money by typical street price) accepted on appeal.
• The opinion distinguished out-of-circuit authorities invoked by appellants—United States v. Frazier and United States v. Lucio—as factually inapt (and, in Lucio, the cited quotation not appearing as represented).

C. Leadership enhancement under §3B1.1

• United States v. Washington emphasized that leadership determinations involve factual nuances; appellate courts defer to district courts’ vantage point.
• United States v. Robinson clarified the review structure: clear-error review of underlying facts and deferential review of the organizer/leader conclusion.

D. Substantive reasonableness and within-Guidelines presumption

• United States v. Parrish framed substantive-reasonableness claims as challenges to the district court’s weighing of 18 U.S.C. § 3553(a) factors.
• United States v. Jones supported the presumption of reasonableness for within-Guidelines sentences.
• United States v. Sexton limited appellate reweighing: disagreement with the district court’s balancing typically fails under abuse-of-discretion review.

E. Firearm enhancement, burdens, and Rule 32 disputes

• United States v. Wheaton (citing United States v. Darwich) placed firearm-possession determinations in the clear-error category; United States v. Wilson (quoting United States v. West) restated the clear-error standard.
• United States v. Gardiner (quoting United States v. Emuegbunam) provided the four-part plain-error test for unpreserved Rule 32 claims.
• United States v. Lang established that to create a “dispute” requiring findings under Fed. R. Crim. P. 32(i)(3)(B), a defendant must produce some evidence beyond a bare denial; otherwise, the court may rely on PSR facts.
• United States v. Mack supported the sufficiency of district-court factfinding where PSR-supported facts are adopted after considering arguments.
• The firearm-enhancement burden structure relied on United States v. Catalan (quoting United States v. Hill) and was supplemented by United States v. Rios (citing United States v. Penaloza) and United States v. Woods (foreseeability for co-conspirator firearm possession).
• Darwich (quoting United States v. Hough) supplied the presumption that once possession is shown, the weapon is presumed connected to the offense; United States v. Greeno clarified that the defendant must rebut with evidence and addressed the “clearly improbable” standard (noting it was “abrogated on other grounds by New York State Rifle & Pistol Ass'n v. Bruen”).
• United States v. Cochran served as a contrast case where foreseeability of a hidden co-conspirator gun was rejected; the panel distinguished it because firearms here were openly present in the stash-house environment.

F. Relevant conduct and particularized findings (plain error posture)

• United States v. Donohue and United States v. Boyd foreclosed plain-error relief premised on lack of particularized findings where the defendant did not request them at sentencing.
• United States v. Louchart supported using relevant conduct beyond plea admissions to support a sentence.

G. Mental health departures/variances and explanation requirements

• United States v. Johns set the procedural reasonableness principle that a sentence may be procedurally unreasonable if the court wholly fails to address legitimate mitigation.
• United States v. Coleman (en banc) limited appellate review of departure denials to cases where the district court erroneously believed it lacked authority.
• United States v. Elliott and United States v. Judge (quoting United States v. Vonner (en banc)) supported affirmance where the record shows the judge heard and considered mental health arguments and explained the sentence sufficiently.

3.2 Legal Reasoning

A. Cash-to-drug conversion: ratio-and-purity methodology upheld

The central Guidelines question was how to approximate drug quantity under U.S.S.G. §2D1.1 when cash believed to be proceeds is seized. The Sixth Circuit accepted the district court’s logic: when a stash house contains multiple drugs and tested purity information, converting cash by using the proportion of seized drugs (and their known purity) can be a “plausible” approximation supported by “competent evidence.”

Two points did most of the work:

• Evidence of meth trafficking beyond controlled buys: Trash-pull evidence (meth residue), packaging materials, and the large quantity of tested “pure methamphetamine” found in distribution-ready packaging supported the inference that methamphetamine trafficking was part of the conspiracy’s scale—even if earlier investigative leads emphasized fentanyl/heroin.
• “Err on the side of caution” satisfied via pricing: The PSR used $250/ounce (the higher end of a $175–$250 range), yielding a more conservative conversion (less drug quantity per dollar). The panel treated this as meeting the “side of caution” principle from Sandridge and Johnson.

The court also rejected the idea that the district court needed evidence of actual meth sales to use meth in converting proceeds, and endorsed the district court’s view that converting proceeds based on unspecified “past” trafficking in other drugs would be more speculative than tethering the conversion to what was “actually seized” and lab-tested during the conspiracy period.

B. Leadership enhancement: control of the hub + operational direction

Applying U.S.S.G. §3B1.1(c), the district court found that Terrance’s rental and control of the stash house made it the “hub” of the conspiracy and that communications showed decision-making authority (pricing, directing co-conspirators, coordinating customer interactions). Under Washington and Robinson, those fact-intensive conclusions deserved deference. The Sixth Circuit treated “shared phone” and “group sales” as consistent with an organizer/leader structure where one participant still controls critical assets and directs others.

C. Firearm enhancement: (1) possession/foreseeability; (2) “clearly improbable” rebuttal

For Darnell, the court reaffirmed a familiar two-stage burden structure under U.S.S.G. §2D1.1(b)(1) and its commentary:

• Government’s burden first: Show by a preponderance that the defendant actually/constructively possessed a weapon during the offense or relevant conduct (or that a co-conspirator’s possession was reasonably foreseeable). Authorities: Catalan, Hill, Woods.
• Presumption and defendant’s rebuttal: Once possession is shown, a presumption arises that the weapon was connected; the defendant must show it is “clearly improbable” the weapon was connected. Authorities: Darwich, Hough, Catalan, Greeno.

The panel read the sentencing colloquy not as burden shifting but as the district judge correctly prompting the defense to meet its rebuttal burden after possession evidence was proffered. The open presence of firearms in the stash-house setting and evidence suggesting Darnell sought access to “my gun” supported the enhancement; Cochran was distinguished because it involved a concealed firearm under a car seat and lack of foreseeability evidence.

D. Rule 32(i)(3)(B): “disputed portion” requires more than bare denial

Darnell’s Rule 32 argument failed under plain-error review and, substantively, because Lang allows a district court to rely on PSR facts when the defendant offers only an attorney’s denial or argument without evidence calling reliability into question. In that posture, the district court’s adoption of PSR-supported facts—after hearing argument—was treated as sufficient “ruling” on the dispute.

E. Hull: departure unreviewable; variance denial adequately explained

The panel separated two ideas often conflated:

• Departure: The refusal to depart under U.S.S.G. §5H1.3 or §5K2.13 was unreviewable under Coleman because the judge recognized authority but found the condition not present to an “unusual degree” and no “significantly reduced mental capacity.”
• Variance: The court did consider schizophrenia under 18 U.S.C. § 3553(a) and explained why it did not warrant a below-Guidelines sentence (finding Hull “fully engaged” and lacking record support for unusual severity/manipulation). Under Johns, Judge, and Vonner, this sufficed procedurally; under Jones and Elliott, it sufficed substantively.

3.3 Impact

Although unpublished, the opinion is a practical roadmap for district courts and litigants in three recurrent federal-sentencing contexts:

• Proceeds conversion anchored to seized evidence: The court signaled comfort with approximating proceeds using the on-scene drug mix and purity results when that methodology is transparent and conservative, reducing incentives for speculative “alternative drug” conversions untethered to tested evidence.
• Role enhancements from “operational control” evidence: Control of key infrastructure (stash house) plus communications showing delegation/price control can support §3B1.1(c) even within a small conspiracy with shared tools (e.g., a “dope phone”).
• Firearm enhancement litigation discipline: Defendants seeking to trigger Rule 32 findings or defeat §2D1.1(b)(1) must present evidence, not just argument. Once possession/foreseeability is shown, the rebuttal must meet the “clearly improbable” bar with record support.
• Mental-health mitigation record building: The opinion illustrates that merely having a diagnosis (even schizophrenia) may not carry the day without evidence of unusual severity, offense-time functional impairment, or concrete exploitation—particularly where the record supports active participation.
