A Pima County judge on Friday dismissed first-degree murder charges against Dirk Prather, ruling the state had not proven beyond a reasonable doubt that he remains a danger to the community, court records show. The ruling followed a defense motion for judgment as a matter of law and prompted the judge to order Prather's immediate release from county custody.
Judge cites insufficient proof of ongoing danger
Judge Mark Hotchkiss granted the defense motion and formally dismissed the murder charge without prejudice, meaning prosecutors may be able to refile if additional evidence emerges. During Friday's court proceedings, the judge determined the prosecution had not met the legal standard required to keep the criminal case moving forward.
"the state did not prove beyond a reasonable doubt that he remains a danger to the community."
Prather had been charged in the April 2025 shooting death of Clayton Bishop. According to court filings, Prather told investigators he shot Bishop in the head while Bishop was asleep and asserted the shooting was in self-defense.
Custody status complicated by federal warrant
Although the murder charge was dismissed and the judge ordered Prather released from Pima County custody, he remains detained on a separate federal warrant. Court documents do not specify the nature of the federal warrant, and local prosecutors declined to provide further detail in court filings.
The Pima County jail roster now lists Prather as being held without bond. News 4 Tucson reported that it reached out to the U.S. Marshals Service for additional information about the federal warrant but had not received a response by the time of reporting.
Guardianship and evidence disposition
During the hearing, the court established Prather's mother as his legal guardian. Judge Hotchkiss also ordered that all exhibits in the case be released, a procedural step that follows dismissal and affects how physical and documentary evidence will be handled going forward.
- Charge dismissed: First-degree murder (April 2025 death of Clayton Bishop)
- Court action: Motion for judgment as a matter of law granted; dismissal without prejudice
- Custody: Ordered released from county custody but still detained on a federal warrant
The dismissal marks a significant turn in a case that has drawn local attention since last year. Prather had previously been held on a $500,000 bond during the criminal proceedings, according to earlier court records. Following Friday's ruling, official records show his status changed to held without bond due to the outstanding federal matter.

Prosecutors may consider whether to refile state charges if additional admissible evidence becomes available. Dismissal without prejudice leaves that option open but does not imply wrongdoing by prosecutors in how the case was handled; rather, it reflects the judge's view about the sufficiency of proof at this stage.
For Tucson residents, the development underscores the often-complex interplay between local and federal detention authorities and the differing burdens prosecutors must meet to sustain criminal charges. It also raises questions about the federal hold that will determine whether Prather remains in custody while any further legal steps are considered.
News 4 Tucson indicated it has contacted the U.S. Marshals Service for clarification on the federal warrant. Local court records and the Pima County jail roster provided the details reported Friday.
Further proceedings or filings in the Pima County court docket could clarify whether state charges are refiled or whether the federal matter results in additional action. For now, the county murder case stands dismissed but not closed.
