Background
On July 26, 2022, Knoxville Police Department SWAT officers responded to a house where Dusty Mink, a felon with outstanding warrants, had barricaded himself inside. During the standoff, officers used tear gas and pepperballs to flush Mink from a bedroom. Officer Chris Hutton testified that he observed Mink holding two weapons: a stockless .22 caliber rifle in one hand and an AR-style pistol in the other. When tear gas took effect, Mink tossed the .22 rifle into the living room and the AR-style weapon (later determined to be a pellet gun) was found at his feet. Officers subsequently recovered a loaded 9mm Ruger handgun, live ammunition, and drug paraphernalia from the bedroom Mink had occupied.
Mink was indicted for aggravated assault, assault, unlawful possession of a weapon by a felon, and evading arrest. The trial court severed the unlawful possession count for separate trial. At trial, the State presented testimony from firearms examiner Lieutenant Brian Dalton, who confirmed the .22 rifle was mechanically functional and capable of firing live ammunition despite the missing stock. The State also introduced recorded jail phone calls in which Mink stated he “had three guns” and “shot one gun in the house so that the police would know ‘this is real.'” In those same calls, Mink claimed police were shooting through the walls at him. Mink testified he was a heavy methamphetamine user experiencing severe hallucinations at the time of the incident and had limited memory of events that day.
The jury convicted Mink of unlawful possession of a firearm by a felon. The trial court sentenced him as a Range III persistent offender to twenty-five years in confinement. Mink appealed on seven grounds, including sufficiency of evidence, the trial court’s denial of continuances for unavailable expert witnesses, exclusion of expert testimony, and failure to give a Ferguson jury instruction regarding lost evidence.
The Court’s Holding
The Tennessee Court of Criminal Appeals affirmed Mink’s conviction and sentence. On the sufficiency of evidence claim, the court applied the deferential Jackson v. Virginia standard, viewing all evidence in the light most favorable to the State. The court found evidence sufficient to support conviction: Officer Hutton’s testimony that he directly observed Mink holding the .22 rifle during the standoff, the firearms examiner’s confirmation that the rifle was operational despite its missing stock, and Mink’s own jail phone call admissions that he possessed firearms during the incident. The court rejected Mink’s arguments that Officer Hutton’s view was obstructed by his gas mask and shield, or that other firearms in the room created reasonable doubt about which gun Mink held.
Regarding the denial of two continuance motions, the court found no abuse of discretion. Although Mink’s original firearms expert died in August 2023 and his neuropharmacology expert Dr. Lipman became unavailable due to a family medical emergency the week before trial, Dr. Lipman ultimately testified at trial. The court noted Dr. Lipman spent more than twenty hours reviewing records and consulting with the defense despite being unable to personally interview Mink before trial. The court also found that Ms. Williams, a private investigator, provided lay testimony about the body camera footage showing multiple guns in a chair, which arguably supported Mink’s theory that the stockless rifle was not in his possession.
The court upheld the trial court’s ruling requiring proof of Mink’s drug use before Dr. Lipman could testify about the effects of methamphetamine on perception and memory. The trial court did not err by requiring some evidentiary foundation—it did not prohibit Mink from establishing drug use through his own testimony or other means. The court rejected a Ferguson instruction claim, holding the State had no duty to preserve other weapons found in the house that officers did not recover, only the weapons Mink was observed holding and later seized.
Key Takeaways
- Constructive possession of a firearm requires evidence the defendant had power and ability to exercise control over it; direct testimony of observation satisfies sufficiency of evidence.
- Trial courts have broad discretion in denying continuances when experts become unavailable, particularly where substitute experts appear and the trial proceeds.
- Expert testimony about drug effects requires some foundational evidence that the defendant actually used the substance; expert testimony cannot be used to back-door evidence the defendant opposes.
- A Ferguson violation claim regarding lost evidence requires proof the State had a duty to preserve it; no such duty exists for evidence officers did not collect from a crime scene.
Why It Matters
This decision reinforces the broad deference appellate courts give to trial court evidentiary rulings and jury verdicts in felon-in-possession cases. Where a law enforcement officer directly observes a defendant holding a firearm and a ballistics expert confirms it is functional, courts will likely find sufficient evidence of possession even if the defendant presents memory-related or alternate theories of the evidence. The decision also clarifies that expert testimony regarding drug-induced hallucinations or paranoia must still rest on an adequate foundation—defense counsel cannot use expert testimony as a workaround to avoid calling the defendant to establish critical facts.
The ruling on continuances reflects courts’ reluctance to delay trials based on expert unavailability unless the defendant demonstrates clear prejudice. Here, despite losing his original firearms expert and facing his neuropharmacology expert’s unavailability, Mink presented expert testimony at trial and was not precluded from offering alternative theories through lay witnesses. The Ferguson instruction denial makes clear that police have no general duty to preserve weapons recovered from a crime scene—only evidence that might play a significant role in the defense must be preserved.
