Ledesma (2006) 39 Cal.4th 641, 709 [murder victim's statements to officer investigating previous robbery occurring 15 minutes before interview properly admitted as spontaneous statements; "court's conclusion that [victim] was under the stress of the event at the time he made the statements is supported by the brief lapse of time . . ., by [the police officer's] statement that he seemed nervous, and by [his employer's] statement that he sounded scared"].)
