Analysis
In State v. Gallegos, the Utah Court of Appeals addressed the challenging intersection of Rules 404(b) and 403 when prosecutors seek to introduce evidence of a defendant’s prior weapon possession to establish constructive possession of a similar weapon.
Background and Facts
Prison guards discovered a homemade shank in a shoe located in the common area of a cell shared by Darrin Gallegos and his cellmate. Initially, both inmates denied ownership, but Gallegos later admitted the weapon was his during multiple interviews and prison disciplinary hearings. After criminal charges were filed, both Gallegos and his cellmate changed their stories, claiming the shank belonged to the cellmate. The State sought to admit evidence that Gallegos had possessed a similar shank four years earlier, cut from the same type of bed frame material.
Key Legal Issues
The central issue was whether evidence of Gallegos’s prior shank possession was admissible under Rule 404(b) for a proper non-character purpose or whether it impermissibly invited a propensity inference. The State argued the evidence was relevant to establish Gallegos’s knowledge, motive, and intent regarding the current shank for constructive possession purposes. The court also addressed the admissibility of gang affiliation evidence and potential sentencing information under Rule 403.
Court’s Analysis and Holding
The Court of Appeals concluded that the trial court abused its discretion in admitting the prior shank evidence. The court found that the State’s proffered purposes—knowledge, motive, and intent—were merely “shorthand for a propensity inference” that Gallegos had a propensity to make and possess prison shanks. The court emphasized that constructive possession requires proving a sufficient nexus between the defendant and contraband, but prior possession evidence primarily suggests the defendant acted in conformity with past behavior. Even if the evidence had some non-propensity purpose, the court concluded its probative value was substantially outweighed by the risk of unfair prejudice under Rule 403. However, the court affirmed the admission of gang evidence and existing sentence information, finding they provided proper motive for the defendants’ changed testimony.
Practice Implications
This decision highlights the difficulty of distinguishing legitimate constructive possession evidence from forbidden propensity inferences. Practitioners should scrutinize whether prior acts evidence truly serves the stated non-character purpose or merely invites jurors to conclude the defendant has a propensity to engage in similar conduct. The court’s analysis demonstrates that even when prior acts evidence might be technically relevant to intent or knowledge, courts must carefully examine whether such relevance depends primarily on character-based reasoning rather than legitimate inferential pathways.

Court
Utah Court of Appeals
Case Number
No. 20190029-CA
Date Decided
December 10, 2020
Outcome
Reversed
Holding
A trial court improperly admits evidence of a defendant’s prior similar weapon possession when offered for constructive possession purposes without a proper non-propensity purpose under Rule 404(b), and such error is not harmless when the prior acts evidence likely influenced the jury’s verdict.
Standard of Review
Abuse of discretion for evidentiary rulings under Utah Rules of Evidence 403 and 404(b)
Practice Tip
When opposing admission of prior acts evidence under Rule 404(b), carefully analyze whether the proponent’s stated purpose is truly distinct from a forbidden propensity inference, particularly in constructive possession cases where the relevance often depends on character-based reasoning.
