State v. Triplett, 368 N.C. 172

On Dec. 9, 2009, Triplett and co-defendants went to the victim's house; a fight ensued and the victim was fatally stabbed. Triplett claimed he blacked out and acted in self-defense.
The State's case included testimony that the group planned to rob the victim and that Triplett knew of that plan; key testimony came from a co-defendant, Triplett’s cellmate, and Triplett’s sister Teresa Ogle.
Ogle testified that Triplett admitted killing the victim, that he took a knife from her kitchen because he knew the victim had a gun, and that he said the group went to get drugs and that Ben planned to rob the victim.
Defense sought to play a late-2011 voicemail Ogle left for another sister, containing hostile statements in the context of an eviction and threats to involve authorities, to show Ogle’s bias against Triplett and the family.
The trial court excluded the voicemail under Rule 403 as more confusing and potentially prejudicial than probative. Triplett was convicted of first-degree felony murder and sentenced to life without parole; the Court of Appeals reversed, ruling exclusion was error and prejudicial.
The North Carolina Supreme Court reversed the Court of Appeals, holding (1) the voicemail was minimally relevant, (2) Ogle was not a uniquely "key" witness given other testimony, and (3) the trial court did not abuse its discretion in excluding the voicemail under Rule 403.

Issue	State's Argument	Triplett's Argument	Held
Admissibility — relevance of voicemail (Rule 401/402)	Voicemail largely unrelated to charged offense; relevance is marginal and tied to later family eviction dispute	Voicemail shows Ogle’s bias and animus toward Triplett/family, bearing on her credibility	Voicemail met low relevancy bar but only barely; trial court treated it as minimally relevant and proceeded to Rule 403 balancing
Admissibility — Rule 403 balancing (prejudice, confusion, cumulative evidence)	Admission would open collateral family-eviction dispute, confuse jury, and be unfairly prejudicial	Excluding the voicemail prevented impeachment of a key State witness and was reversible error	Trial court did not abuse discretion: probative value was weak and substantially outweighed by danger of confusion and prejudice
Prejudice / Harmlessness (whether exclusion was reversible)	Exclusion did not prejudice Triplett because other witnesses corroborated knowledge of robbery plan; Ogle was not indispensable	Ogle was a key witness whose credibility was central to felony-murder predicate; exclusion was prejudicial	Court held Ogle was not uniquely essential—other witnesses testified to robbery plan—so any bias impeachment was less probative; exclusion not reversible error
