In what circumstances will a defendant be found guilty of attempted murder by the Court of Appeal for an armed robbery?

Appellants also cite People v. Nguyen (1988) 204 Cal.App.3d 181, in which the defendant entered a market with an accomplice, both armed. The confederate took a clerk to the rear of the store; the defendant stayed up front. After the defendant shouted a "Vietnamese battle phrase used when 'someone was to kill or be killed,'" the confederate shot the victim. (Id. at p. 185.) The Fourth Appellate District held "the evidence supports a finding of ... use of a firearm during the robbery but not the attempted murder." (Id. at p. 194.)
