State v. Jones, 365 P.3d 1212

On March 7, 2011, Kamas Police Chief Adam Jones (one of two officers in town) received a personal cellphone call from D.M., his brother Travis’s girlfriend, asking him to "come over and talk or take care of [Travis]."
Jones, on duty and in uniform, drove his police car to Travis’s house, spent ~15–20 minutes there, observed alcohol and minor injuries/allegations, told Travis to go to bed, and offered to contact the Summit County Sheriff (D.M. declined).
Jones did not file a report or provide statutorily required written notice to the alleged victim under the Cohabitant Abuse Procedures Act; later that evening the sheriff responded, arrested Travis, and discovered Jones had been at the house earlier.
The State charged Jones with official misconduct (Utah Code § 76-8-201) for knowingly refraining from duties imposed by the Cohabitant Abuse Procedures Act, and with witness tampering (Utah Code § 76-8-508(1)) for allegedly inducing false testimony by telling Travis and a jailer that Travis had been asleep when Jones was there.
At the preliminary hearing the magistrate declined bindover; the Utah Court of Appeals affirmed, reasoning the initial call was personal and there was insufficient evidence of belief that an investigation was imminent; the Utah Supreme Court granted certiorari and reversed, holding the State met the low probable-cause/bindover standard.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether evidence supported bindover for official misconduct for failing to perform duties after responding to a domestic violence allegation	Jones responded (or, after arrival became responsible) as an officer to an allegation of domestic violence and knowingly refrained from statutory duties to benefit himself/brother	Jones responded solely as a family member on a personal call, repeatedly offered to summon sheriff, and therefore statutory duties were not triggered	Reversed: viewing evidence in light most favorable to prosecution, sufficient probable cause existed to bind over for official misconduct
Whether evidence supported bindover for witness tampering for statements after arrest	Jones, believing an investigation was likely, sought to induce testimony that Travis had been asleep to prevent an investigation	Jones was merely checking on his brother; his statements were innocent and there was no evidence he believed an investigation was imminent	Reversed: sufficient evidence for a reasonable officer to conclude Jones believed investigation was imminent and attempted to induce false testimony; bindover proper
