Proving a crime of intimate partner or sexual violence challenges prosecutors to place the criminal act in its proper context. It is important to present the fullest possible picture of the relationship to enable the jury to understand how and why the crime occurred and to explain victim behaviors such as recantation, minimization, or remaining with the abuser. In the prosecution of sexual violence, prior acts by the offender against other victims may be essential to proof of identity or to reveal the offender's calculated strategies to exploit the victim's vulnerability. This training will identify types of evidence that may be admissible for purposes permitted under the Rule 404(b), which is primarily a rule of preclusion--evidence of other crimes or "bad acts" are inadmissible to prove the defendant's bad character or propensity to commit a particular crime, but the Rule permits such evidence to be introduced for certain proper purposes. The presenter will suggest ways in which admissibility under the Rule can be argued, and discuss important considerations to avoid reversible error on appeal.
