A polygamous sect leader already serving a 50-year federal prison sentence has been convicted on Arizona state child abuse charges after three girls were found inside an enclosed trailer he was towing through Flagstaff.
Samuel Bateman, a self-described prophet linked to an offshoot of the Fundamentalist Church of Jesus Christ of Latter-day Saints, was found guilty Friday on three counts of child abuse. The case stemmed from a 2022 traffic stop after a person reported seeing small fingers reaching through gaps in the doors of a trailer being hauled on an Arizona highway.
When police stopped Bateman’s vehicle, officers found three girls inside the enclosed trailer. They were between 11 and 14 years old at the time. Authorities said the trailer had poor ventilation and contained a makeshift toilet, a sofa and camping chairs. Prosecutors argued that transporting children in those conditions on a hot day created an obvious safety risk.
The state case was separate from Bateman’s federal conviction, but it added another layer to a broader criminal history involving abuse and control of minors. Bateman is already serving a 50-year federal sentence after pleading guilty to charges connected to transporting a minor for criminal sexual activity and a kidnapping conspiracy.

Federal authorities have said Bateman used religious authority to control followers and exploit children. He previously claimed to have more than 20 “spiritual wives,” including underage girls. His case has also received renewed public attention because of the Netflix documentary series Trust Me: The False Prophet, which examines allegations against him and the network around his group.
During the Arizona trial, Bateman represented himself. He told jurors he did not intend to harm the girls and claimed he believed they had gotten out of the trailer during a stop. Under questioning, however, he acknowledged knowing that the girls had been in the trailer for hours and that the ventilation was poor.
Prosecutors urged jurors to focus on common sense and the physical conditions inside the trailer. They argued that a cargo-style trailer was not a safe place to carry children, especially in hot weather and without proper airflow.
The jury deliberated for about 40 minutes before convicting Bateman on all three counts. Each count carries a mandatory prison sentence of four to eight years. Sentencing is scheduled for August 25.
The judge had previously ruled that jurors should not hear about Bateman’s federal conviction. However, Bateman reportedly mentioned it himself during the trial while representing himself, leading the judge to strike those comments from the record.
The case highlights the difficulty of prosecuting abuse allegations involving closed religious communities or high-control groups. Authorities have said Bateman traveled across several states, including Arizona, Utah, Colorado and Nebraska, while building a breakaway network connected to the history of the FLDS movement.
The mainstream Church of Jesus Christ of Latter-day Saints abandoned polygamy in 1890 and strictly prohibits the practice today. The FLDS movement and its offshoots have long been separate from the mainstream church. Bateman was previously described as a follower of Warren Jeffs, the former FLDS leader who is serving a life sentence in Texas for child sexual assault.
The communities historically associated with the FLDS, including Colorado City, Arizona, and Hildale, Utah, have changed significantly over the past decade. Court supervision and reforms weakened the sect’s control over local government and policing. Still, prosecutors and survivor advocates have warned that smaller offshoot groups can continue operating outside public view.
For ordinary people, the Arizona case is a reminder of how quickly a safety concern reported by a bystander can lead to a larger investigation. The report about small fingers visible from the trailer door led police to stop the vehicle and eventually helped expose further concerns about Bateman’s treatment of children.
The case also raises broader questions about child protection, religious authority and isolation. When children are placed under the control of adults who claim spiritual power, outside oversight can become more difficult. That makes reports from neighbors, witnesses, former members and law enforcement especially important.
While Bateman is already facing decades in prison from the federal case, the Arizona conviction gives the state its own judgment on the trailer incident. For prosecutors, the verdict confirms that the conditions in which the girls were transported amounted to criminal abuse.
Why It Matters
The case underscores the risks children can face inside isolated or high-control groups, especially when adults use religious authority to control families and minors. It also shows the importance of bystander reports and law enforcement follow-up in possible child endangerment cases. For the public, the verdict adds another accountability step in a case already tied to federal abuse and kidnapping convictions.
What Comes Next
Bateman is scheduled to be sentenced in the Arizona child abuse case on August 25. He is already serving a 50-year federal prison sentence, but the state convictions could add additional prison time. The case is also likely to remain part of broader public discussion about child protection, polygamous sect offshoots and abuse inside closed communities.
