State of Hawai'i v. Casey Duncan

Summary

The Supreme Court of Hawai'i reviewed Casey Duncan's conviction for first-degree theft arising from his participation in melting stolen jewelry. The court held that the prosecution improperly introduced extrinsic evidence of Duncan's prior inconsistent statements without laying the foundation required by Hawai'i Rules of Evidence Rule 613. Because the error could have affected Duncan's credibility and defenses, the court vacated the conviction and sentence and remanded for further proceedings.

Holdings

1. Evidence of Tempkins's prior bad acts, known to Rogers but not shown to have been known by Duncan, was not relevant to Duncan's claim that he was coerced into melting the stolen gold and was therefore inadmissible under HRE Rule 402.
2. When extrinsic evidence of a witness's prior inconsistent statement is offered specifically to impeach the witness, the prosecution must comply with HRE Rule 613(b)'s foundation requirements even if the statement also qualifies as a party-opponent admission under HRE Rule 803(a)(1).
3. The erroneous admission of Detective Staszyn's testimony was not harmless because there was a reasonable possibility that it contributed to Duncan's conviction.
4. Substantial evidence supported Duncan's conviction for first-degree theft, including evidence that he intentionally exerted control over and deprived the jewelry store of property worth more than $20,000.
5. The trial court did not abuse its discretion by admitting McCoy's rebuttal testimony because it was offered solely to attack Duncan's credibility after Duncan testified and did not merely supply evidence that should have been presented in the prosecution's case-in-chief.

Questions Presented

1. Whether the trial court properly excluded testimony about Tempkins's prior bad acts as irrelevant to Duncan's duress defense.
2. Whether the trial court abused its discretion by admitting the employer's rebuttal testimony attacking Duncan's credibility.
3. Whether the prosecution could introduce Duncan's prior inconsistent statements through Detective Staszyn without first satisfying HRE Rule 613(b)'s foundation requirement.
4. Whether the erroneous admission of Detective Staszyn's testimony was harmless.
5. Whether substantial evidence supported Duncan's conviction for first-degree theft.
