Background
On January 28, 2018, Powell and Darron Blackwell engaged in an altercation in the Western Heights housing project in Knox County. Blackwell jumped out of a white SUV and approached Powell saying “there’s the guy that robbed us.” The two men began fighting physically. Multiple witnesses testified that Powell was the first to brandish a weapon—a .22 caliber pistol—and held it to the back of Blackwell’s head, attempting to fire it. When the gun failed to discharge, Powell and Blackwell tumbled down a grassy embankment, where Powell abandoned the gun and pulled out a box cutter. He slit Blackwell’s throat, causing serious injury that resulted in permanent nerve damage and loss of feeling in the right side of Blackwell’s face. Blackwell retrieved his own gun and fired at Powell as he fled the scene.
Powell was charged with attempted first degree murder, three counts of aggravated assault, firearms violations, and drug possession charges. A jury convicted him of the lesser included offense of attempted voluntary manslaughter, three counts of aggravated assault (which the trial court merged), and drug and trespassing offenses. Powell received a ten-year sentence and appealed, arguing insufficient evidence and claiming self-defense.
The Court’s Holding
The appellate court affirmed the conviction and sentence. Applying the standard that evidence must be viewed in the light most favorable to the prosecution, the court found sufficient evidence for attempted voluntary manslaughter. Although Powell argued Blackwell was the initial aggressor, the jury determined Powell acted “in a state of passion produced by adequate provocation sufficient to lead a reasonable person to act in an irrational manner”—the legal standard for voluntary manslaughter. The jury properly rejected Powell’s self-defense claim, which is fundamentally a factual determination reserved for the jury’s sole discretion.
The court further upheld the three aggravated assault convictions. First, Powell’s throat-cutting caused serious bodily injury satisfying the statutory definition. Second, Powell’s use of the box cutter constituted use of a deadly weapon under Tennessee law. Third, Powell’s act of holding the gun to Blackwell’s head and attempting to fire it caused Blackwell to reasonably fear imminent bodily injury. Under appellate review standards, all conflicts in witness testimony are resolved in favor of the guilty verdict, and the jury’s credibility determinations are binding on appeal.
Key Takeaways
- Self-defense is exclusively a jury question; appellate courts defer to the jury’s rejection of self-defense claims.
- Being the initial physical aggressor does not necessarily defeat assault charges if the defendant was the first to display a deadly weapon.
- A box cutter qualifies as a “deadly weapon” under Tennessee law capable of causing serious bodily injury.
- Serious bodily injury with protracted or permanent functional impairment—such as nerve damage from a throat laceration—supports an aggravated assault conviction.
- On sufficiency of evidence review, the appellate court views all evidence favorably to the conviction and applies only the minimal standard of whether any rational jury could find guilt beyond reasonable doubt.
Why It Matters
This decision clarifies that a self-defense claim will not succeed where the defendant was the first to brandish a deadly weapon, even if there was prior physical confrontation or verbal provocation. The escalation to displaying a firearm places the defendant in a weak position to claim defensive necessity. The case also establishes that Tennessee courts recognize various weapons—including everyday tools like box cutters—as deadly weapons when used to inflict serious injury.
For practitioners, the decision reinforces that sufficiency-of-evidence appeals face an extremely high bar. The appellate court will not reweigh witness credibility, resolve conflicts in testimony, or substitute its inferences for the jury’s. A guilty verdict, once rendered, accredits the prosecution’s case and raises a presumption of guilt that the convicted defendant must overcome—a burden satisfied only in rare cases where no rational jury could find guilt beyond a reasonable doubt.
