Summary: written with AI from the case record.

What it's about
The Court refused to hear the case (denied review) and did not decide either question.
The petition asked whether courts must apply Batson's three-step jury-selection analysis in order and whether a substitute medical examiner may rely partly on an autopsy report by an examiner who did not testify.
Question presented
1. When a defendant raises a challenge during jury selection, under Batson v. Kentucky, 476 U.S. 79 (1986), is the trial court required to apply Batson’s three-step analysis sequentially? 2. Is the admission of a substitute medical examiner’s expert opinion, based in part on an autopsy report prepared by a non-testifying medical examiner, contrary to this Court’s decision in Smith v. Arizona, 602 U.S. 779 (2024)?
