Facts

The complaining witness testified that defendant, wearing a ski mask and carrying a knife, forced her into her home and compelled sexual intercourse and a deviate sexual act. Defendant admitted a prior sexual relationship with the complainant but claimed the encounter was consensual and denied using a mask, knife, or force. Over objection, the trial court admitted testimony about the parties' prior relationship, including a prior forced sexual intercourse after the relationship ended, threats involving her children, assaults, and harassing conduct toward her and her companion. The court also found the complainant's seven-year-old daughter competent to testify, and the child stated that defendant "hopped on my ma's back."

Issue

Whether the trial court erred by admitting evidence of prior incidents between defendant and the complainant, including a prior nonconsensual sexual act and other threatening or assaultive conduct, and whether the court erred in finding the complainant's seven-year-old daughter competent to testify.

Rule

Evidence of other misconduct is admissible if it tends to prove a fact in issue or shows motive, intent, identity, absence of mistake, or modus operandi, but it is inadmissible if relevant only to show propensity. In a rape case where consent is disputed, prior incidents between the accused and the complainant may be admitted if they are relevant to the complainant's state of mind and whether she in fact consented, though such evidence may not be admitted solely to enhance credibility or provide independent corroboration. A child witness is competent when the trial court finds the child can receive accurate impressions, recollect, understand questions, express answers, and appreciate the moral duty to tell the truth.

In a sexual assault prosecution in Chicago, Dana Ruiz testifies that Leo Mercer forced intercourse after following her into her apartment. Leo admits they had been intimate during a prior dating relationship and claims Dana invited him over and consented. The prosecution offers evidence that after Dana ended the relationship, Leo previously forced sex on her and later threatened to harm her younger brother if she kept seeing other people.

Should the trial court admit the prior-incident evidence over Leo's objection?

Explanation. When consent is the principal issue and the defendant relies on a prior consensual relationship, prior incidents between the accused and complainant may be admitted if they are probative of whether the complainant in fact consented. The majority rejected propensity reasoning and also rejected intent as the proper theory in this context. The evidence is admissible here because it tends to show the complainant's state of mind and how the relationship had deteriorated.
