Utah Court of Appeals hears argument on whether child-abuse and gun charges should have been tried separately

The Utah Court of Appeals heard oral argument on the question of whether the district court erred by denying a motion to sever child sexual-abuse charges from later assault and weapons and assault charges in State v. Christiansen.

Appellant counsel Rachel Phillips Zanescoff told the court that "the district court abused its discretion and denied Isaac's motion to sever the abuse charges," arguing that the Utah statute governing joinder requires either a same-conduct connection or a common scheme or plan and that the record here lacks the necessary connection. Zanescoff stressed that evidence at trial showed Isaac Christiansen was intoxicated and confused during the events and argued the state could have presented the background of the call and police response without offering the detailed sexual-assault testimony that she says prejudiced the jury.

State counsel Jonathan Bauer countered that the trial court acted within its discretion and that Christiansen had not met the appellant's burden to show prejudice. Bauer pointed to testimony, a 911 recording and body-camera video and said the evidence supporting the sexual-abuse counts and the shotgun/assault evidence was strong. He told the court the combined evidence explained why those who responded did so and that, even if tried separately, certain facts from one incident could be admissible in the other as background or as evidence of consciousness of guilt.

The lawyers debated the statutory standard for joinder (as described in briefing to the court), the meaning of "precipitation" or "facilitating" conduct cited in case law, and whether temporal proximity alone suffices to show the required connection. Zanescoff argued that the absence of evidence that Christiansen knew the abuse had been disclosed to others weighs against joinder; Bauer replied that the overall sequence and corroborating evidence allowed a jury to see the events as part of a single narrative. Both sides addressed whether Rule 403 and Rule 404 objections could have and would have limited certain evidence if the trials had been severed.

On the contested forensic evidence, Zanescoff pointed to testimony and briefing that the serology result identified human alpha-amylase (not conclusively saliva) and that an expert had testified about other possible sources and about collection issues; the defense argued that those factual gaps supported reasonable doubt on the abuse counts. Bauer emphasized testimony the prosecution relied on, including DNA profiles identified through the swab and witness testimony, and argued those facts undercut any claim of prejudice from joinder.

The bench asked detailed questions about (1) the legal standard and standard of review for motions to sever, (2) whether the assault/gun evidence would be admissible in a separate abuse trial as consciousness of guilt or background, and (3) whether a severance would have produced a reasonable likelihood of a different outcome on any count. The court also questioned defense counsel about specific evidentiary points (for example, what DNA testing showed and whether the presence of certain markers could be explained by household contact).

After oral argument the panel took the case under advisement and said it would issue a written opinion. The court did not announce an immediate ruling from the bench.
