Quick Summary
The Arizona Supreme Court reversed Dolan Chapple’s convictions due to the trial court’s admission of prejudicial photographs and exclusion of expert testimony, impacting his right to a fair trial.
Facts of the Case
Dolan Chapple faced charges of first-degree murder and drug-related offenses after an alleged involvement in a triple homicide during a failed drug deal. Witnesses identified him as “Dee,” who purportedly confessed to the murders. Chapple, however, claimed he was in Illinois at the time.
The prosecution introduced graphic photographs of the crime scene, which Chapple argued were inflammatory and unnecessary since he did not contest the cause of death. He offered to stipulate to this fact to prevent jury prejudice.
Chapple also sought to introduce expert testimony from Dr. Elizabeth Loftus on the unreliability of eyewitness identifications, which the trial court excluded. He was convicted and sentenced to life imprisonment without parole for 25 years on each murder charge, alongside concurrent sentences for drug offenses.

I.R.A.C. Format
Issue
Whether the admission of inflammatory photographs and exclusion of expert testimony on eyewitness identification violated Chapple’s right to a fair trial.
Rule of Law
The admissibility of evidence is determined by its relevance under Rule 401, which assesses if evidence makes a fact more or less probable than it would be without it.
Rule 403 allows for the exclusion of relevant evidence if its probative value is substantially outweighed by the risk of unfair prejudice.
Expert testimony is admissible under Rule 702 if it aids the trier of fact in understanding evidence or determining a fact in issue.
Reasoning and Analysis
The court evaluated whether the probative value of the photographs justified their prejudicial impact. Although relevant to show the crime’s nature, their graphic content risked unfairly biasing the jury against Chapple, especially since he agreed to stipulate to the cause of death.
Regarding the exclusion of expert testimony, Rule 702 requires that such testimony assist jurors in understanding complex issues. Dr. Loftus’s insights on eyewitness identification reliability could have been crucial for assessing witness credibility, given factors like time lapse and stress conditions. The exclusion potentially denied jurors important context for evaluating witness reliability.
Conclusion
The Arizona Supreme Court reversed Chapple’s convictions and remanded for a new trial, finding that admitting prejudicial photographs and excluding expert testimony constituted an abuse of discretion.
Dissenting Opinions
Justice Hays dissented in part, expressing concern that allowing expert testimony on eyewitness identification could undermine jury assessment of witness credibility and cautioned against opening doors for academic encroachment on jury functions.
Key Takeaways
- The probative value of evidence must outweigh its potential for unfair prejudice under Arizona Rules of Evidence.
- Admissibility of gruesome photographs should be carefully considered, especially when the cause of death is not disputed.
- Excluding expert testimony on eyewitness identification can significantly impact a defendant’s right to a fair trial.
- Expert insights can assist jurors in understanding complex issues like the reliability of eyewitness identification.
- Reversal of convictions can occur when evidentiary decisions potentially bias the jury and impair fair trial rights.
