When is evidence intrinsic to charged crimes under rule 404(b)? State v. Blackwing Explained

In State v. Blackwing, the Utah Supreme Court provided crucial guidance on when evidence of uncharged acts is considered intrinsic to charged crimes and thus exempt from rule 404(b) analysis. The case arose when the State sought to introduce evidence of defendant’s sexual assault of the alleged murder victim and his manipulative control over co-conspirators.

Background and Facts

Blackwing was charged with solicitation, conspiracy, and attempted murder after allegedly orchestrating from jail the killing of fourteen-year-old C.G. to prevent her testimony in his rape case. He allegedly directed three women in his polygamous household to murder C.G. and her parents. The district court excluded most evidence of the underlying rape case, Blackwing’s prior rape conviction involving co-conspirator Tina, and specific acts showing his manipulation and control over the women.

Key Legal Issues

The central issue was whether the proposed evidence constituted “other acts” subject to rule 404(b) or was intrinsic evidence exempt from that rule’s restrictions. The court also addressed the proper application of rules 402 (relevance) and 403 (prejudice balancing).

Court’s Analysis and Holding

The court adopted a clear standard: evidence is intrinsic when there is a direct relationship between the act and the charged crime. Such evidence must be “directly connected to the factual circumstances of the crime and provides contextual or background information.” The court rejected narrow definitions limiting intrinsic evidence to acts necessary to prove elements or occurring contemporaneously with charged crimes.

Applying this standard, the court found Blackwing’s sexual assault of C.G. was intrinsic because it directly motivated the alleged murder conspiracy. Similarly, his manipulation of co-conspirators was intrinsic because it explained how the conspiracy was formed and why he selected these particular women. However, the court affirmed exclusion of Blackwing’s rape conviction under rule 403.

Practice Implications

This decision provides valuable guidance for practitioners handling rule 404(b) issues. When seeking to admit evidence of uncharged acts, attorneys should focus on demonstrating the direct relationship between the act and charged crime rather than merely arguing the evidence provides helpful context. The court’s framework requires showing the act is an “integral and natural part” of the circumstances surrounding the offense, not just tangentially related background information.
