The following excerpt is from People v. Romero, A142774 (Cal. App. 2016):
Here, by contrast, the court did not give CALCRIM No. 3471, and the defense argument did not rely on the principle that if the defendant started the fight using nondeadly force and the opponent suddenly escalates to deadly force, the defendant may defend himself or herself using deadly force. (People v. Quach (2004) 116 Cal.App.4th 294, 301-302.)
