Case Brief Summary & Legal Analysis
tl;dr: The court reversed a murder conviction, finding the trial court erred by excluding expert testimony on the unreliability of eyewitness identification—the sole issue at trial—and by admitting gruesome photographs of the victim when the facts they depicted were undisputed.
Legal Significance: This case established a foundational precedent for admitting expert testimony on eyewitness identification under Rule 702 in specific, complex cases and clarified the Rule 403 balancing test, holding that inflammatory evidence has minimal probative value when the facts it depicts are uncontested.

Case Facts & Court Holding
Key Facts & Case Background
Dolan Chapple was convicted of three counts of first-degree murder based solely on the eyewitness identification of two accomplices, Malcolm Scott and Pamela Buck, who had been granted immunity. The identification occurred more than a year after the crime. The defendant’s only defense was mistaken identity. He presented an alibi and argued the witnesses’ identification was unreliable due to factors such as the long time delay, the stressful nature of the event, their marijuana use, and potential witness collaboration. Scott had previously failed to identify the defendant in a photo lineup and had tentatively identified another man, James Logan, as resembling the perpetrator. To support his defense, Chapple offered the expert testimony of Dr. Elizabeth Loftus on scientific principles of perception and memory affecting eyewitness reliability. The trial court excluded this testimony. The State introduced several graphic, color photographs of a victim’s charred body and skull to show the cause of death. The defense did not contest the cause of death, the manner of the killing, or the victim’s identity, and offered to stipulate to these facts. The trial court admitted the photographs over the defendant’s objection.
