People v. Martinez
Facts
After Martinez was arrested for the Balboa Park shooting, she admitted in a police interview that she shot at the victims and, when asked if she had ever done it before, said she had shot at people in Chicago though she had not shot anyone. At trial, Martinez testified, in response to defense counsel, that she "wouldn't shoot anybody," but if she had to, she would shoot Cusick. On cross-examination, the prosecutor used her prior statement to police to impeach that testimony. Martinez argued the statement was not truly inconsistent and also claimed it should have been excluded because there was no independent proof of any prior shooting.
Issue
Was Martinez's statement to police that she had previously shot at people admissible to impeach her trial testimony, and did the corpus delicti rule require independent proof that the prior uncharged shooting conduct actually occurred before the statement could be admitted for that purpose?
Rule
A prior statement is admissible for impeachment as a prior inconsistent statement when the trial court reasonably finds it inconsistent with the witness's trial testimony, and appellate courts defer to the trial court's assessment of the testimony's meaning, demeanor, and tone. The corpus delicti rule requires independent proof of the corpus delicti of a crime before an accused's extrajudicial admission may establish that crime, but the rule has not been applied to uncharged other-crimes evidence offered solely for impeachment, where admissibility rests on the inconsistency itself rather than proof that the prior statement was true.
