952 F.3d 728
6th Cir.2020Background
- Between Aug. 22–24, 2016 Wesley Hamm purchased fentanyl/carfentanil from Robert Shields in Cincinnati and supplied Tracey Myers in Mt. Sterling, KY; Myers sold packets that same day to L.K.W., who overdosed and died.
- Myers later smuggled drugs into the county jail and gave doses to three cellmates, who suffered serious overdoses but survived after prompt medical care; Myers later died by suicide.
- A grand jury indicted Hamm, Shields, and Jennifer Hamm; Hamm and Shields were tried and convicted of conspiracy (21 U.S.C. § 846) and two counts of distributing carfentanil (21 U.S.C. § 841(a)), with the jury finding the § 841(b)(1)(C) death-or-injury sentencing enhancement applicable to both distribution counts.
- District court sentenced Hamm to 35 years and Shields to life (Shields had a prior felony drug conviction triggering life under the enhancement).
- On appeal the Sixth Circuit affirmed the convictions, rejected the prosecutorial-misconduct claim and most sufficiency challenges, but held the jury instructions misstated law by allowing Pinkerton liability to trigger the § 841(b)(1)(C) enhancement; the court vacated the sentences and remanded for a new trial limited to the enhancement issue.
Issues
| Issue | Plaintiff's Argument (Gov't) | Defendant's Argument (Hamm/Shields) | Held |
|---|---|---|---|
| Sufficiency of evidence for conspiracy (Count 1) | Evidence (texts, trips, repeated purchases, planning, offers to build relationships) supports tacit agreement and joint distribution. | Relationship was only buyer–seller; only two transactions and short duration; insufficient to prove conspiracy. | Affirmed: circumstantial evidence (quantity, planning, exclusivity) permitted a reasonable juror to find a conspiracy. |
| Causation for death enhancement regarding L.K.W. (Count 2) | Carfentanil at measured levels was a but-for cause of death; experts so testified; drug combined with methamphetamine. | Methamphetamine or intervening acts (Myers’ sale) broke causal chain; Hamm not proximate cause. | Affirmed: expert testimony supported but-for causation and combination theory; jury could credit causation and convict. |
| Prosecutor’s closing remark (stating facts not in evidence linking tested drugs to Myers) | Statement was reasonable summation; evidence overall supported link. | Prosecutor asserted facts not in evidence (linking lab-tested bags to Myers). | No plain error: remark was isolated, not deliberate, and not prejudicial given trial context. |
| Use of Pinkerton to apply § 841(b)(1)(C) enhancement | Pinkerton vicarious liability can be used to hold co-conspirators liable for substantive distributions and thus to trigger the enhancement. | Swiney requires the enhancement to be applied only if defendant was part of the distribution chain to the victim; Pinkerton cannot be broadened to impose the enhancement at sentencing. | Reversed as to sentencing: Pinkerton cannot be used to apply the § 841(b)(1)(C) death-or-injury enhancement; jury must find defendant was part of the distribution chain. Sentences vacated and remanded for new trial solely on enhancement issue. |
