What is the legal test for overturning a verdict in a case where the jury was instructed on the kill zone theory?

If a jury has been instructed on the kill zone theory in error, reversal is not automatic. Instead, we review the error for prejudice under the standard articulated in Chapman v. California (1967) 386 U.S. 18, 24. (People v. Aledamat (2019) 8 Cal.5th 1, 13.) Under this standard, "[t]he reviewing court must reverse the conviction unless, after examining the entire cause, including the evidence, and considering all relevant circumstances, it determines the error was harmless beyond a reasonable doubt." (Ibid.) In other words, the reviewing court must determine beyond a reasonable doubt that a reasonable jury would have rendered the same verdict absent the error. (Canizales, supra, 7 Cal.5th at p. 615.)
