USA v Johntavis Matlock, 23-3374
U.S. Court of Appeals, Seventh Circuit Criminal Drug Crimes
Holdings
- Seventh Circuit affirms § 841(b)(1)(C) conviction, finding sufficient evidence of 'but-for' causation under Burrage despite absence of toxicology testing.
- Presence of other drugs or health conditions does not defeat but-for causation where defendant's drug was 'the straw that broke the camel's back.'
- Useful for drug-crime defense and prosecution attorneys litigating causation elements in overdose-related distribution cases under 21 U.S.C. § 841.
Summary
Johntavis Matlock was convicted by a jury in the Southern District of Indiana of distributing heroin resulting in serious bodily injury, felon-in-possession of a firearm, and possession of a controlled substance; he was acquitted on a related count alleging distribution resulting in death. Matlock unsuccessfully moved twice for judgment of acquittal under Rule 29(a), and the district court sentenced him to 420 months' imprisonment. On appeal, he challenged only the sufficiency of the evidence supporting 'but-for' causation on the serious-bodily-injury count.
The Seventh Circuit affirmed, applying the Burrage v. United States standard for but-for causation, which can be satisfied either by showing the drug was independently sufficient to cause the harm or that it combined with other factors as the decisive contributing cause. The court found the jury instructions properly tracked Burrage, distinguishing this case from Krieger, where the district court failed to apply the correct causation standard at all. The evidence supporting causation included testimony from Wiley's mother and medical personnel describing a heroin-induced overdose, Wiley's own statements to first responders that she had used heroin, Matlock's admission that he distributed heroin to her that day, incriminating text messages, and EMT testimony that her symptoms and rapid response to Narcan were consistent with an opioid overdose rather than diabetic shock.
The court rejected Matlock's arguments regarding other drugs present, lack of toxicology testing, possible prescription interactions, and timing gaps, relying on Perrone for the principle that other contributing substances do not preclude a finding that the defendant's drug pushed the victim over the edge. The decision reinforces that appellate review of sufficiency challenges is highly deferential, and reaffirms the practical application of the Burrage causation framework in drug distribution injury cases.
In short
A jury may find 'but-for' causation under 21 U.S.C. § 841(b)(1)(C) where the defendant's drug was either independently sufficient to cause the injury or served as a contributing 'last straw' cause, per Burrage v. United States.
The presence of other drugs, absence of toxicology testing, or possible interacting factors does not defeat a but-for causation finding when sufficient circumstantial and testimonial evidence supports the jury's verdict.
Jury instructions that correctly track the Burrage 'but-for' causation standard distinguish a case from Krieger, where the district court failed to apply that standard.
Appellate review of a Rule 29(a) sufficiency challenge is highly deferential; courts will not reweigh evidence or disturb credibility determinations made by the jury.
