Background

Deperryon Deanthonydesean King was convicted by a jury of first-degree murder and several firearm offenses arising from the fatal shooting of Monte Wilson at a Father’s Day block party. Witnesses gave conflicting accounts of the confrontation, including whether Wilson possessed or fired a gun. Investigators found photographs on King’s phone showing him at the party aiming a firearm.

The defense presented no witnesses and argued that the prosecution had failed to prove its case or, alternatively, that any shooting by King was self-defense. On remand, the trial court held an evidentiary hearing concerning counsel’s failure to investigate and call Deshawn Reed-Davenport and Emilio Zamora, who claimed Wilson was intoxicated, aggressive, armed, and the first person to shoot. The trial court found both witnesses not credible and denied King’s motion for a new trial.

The Court’s Holding

The Court of Appeals affirmed. It held that King failed to establish prejudice from counsel’s failure to investigate or call Reed-Davenport and Zamora. Much of their proposed testimony duplicated evidence presented at trial, and the trial court did not clearly err in finding their testimony that Wilson fired first unreliable. Their relationships and communications with King, inconsistencies in their accounts, and evidence contradicting Zamora’s claim that King was unarmed supported that credibility determination.

The court also rejected King’s argument that counsel conceded guilt during closing argument. Read in context, counsel pursued alternative theories of insufficient evidence and self-defense without admitting that King shot Wilson. Finally, counsel was not ineffective for declining to object when forensic pathologist Dr. David Moons characterized the manner of death as homicide because Moons was qualified to give that opinion and used “homicide” as a forensic classification meaning death caused by another person, not as a legal conclusion establishing criminal guilt.

Key Takeaways

  • Failure to call defense witnesses does not warrant a new trial without a reasonable probability that their testimony would have changed the verdict.
  • Cumulative testimony from witnesses whom the trial court reasonably found not credible did not establish prejudice under the ineffective-assistance standard.
  • A forensic pathologist may classify a death as a homicide when explaining the medical manner of death, and counsel is not ineffective for declining to make a futile objection.

Why It Matters

The decision illustrates the difficulty of proving ineffective assistance based on uncalled witnesses, particularly after an evidentiary hearing produces adverse credibility findings. Appellate courts assess the proposed testimony in light of the full trial record and defer to supported trial-court credibility determinations.

It also distinguishes a strategic closing argument presenting alternative defenses from an unauthorized concession of guilt and recognizes that “homicide” can carry a limited forensic meaning that does not decide whether a defendant committed a crime.
