Investigators say footage from inside a Tremonton home conflicted with the account given during a 911 call.
TREMONTON, Utah — Surveillance video from inside a northern Utah home helped turn an 11-year-old boy’s reported hanging into a child homicide case against his father and a torture case against both parents, police said.
Brigham Young Merrell, 35, and Melinda Marie Merrell, 36, were arrested in May after investigators spent months reviewing the Sept. 21, 2025, death of Moroni Merrell. Police say the video, forensic findings and interviews with children contradicted the first report that Moroni had been found hanging by a coaxial cable. Brigham Merrell is charged with child abuse homicide and child torture. Melinda Merrell is charged with child torture.
The video evidence described by police begins before the scene that Brigham Merrell reported to dispatchers. According to the arrest affidavit, footage showed him carrying Moroni from a different room and into the upstairs bedroom where the alleged hanging was said to have happened. Police said one clip showed him carrying the child past first responders who were actively knocking at the door. He did not stop to let them in, investigators said, and instead continued to the room that became the focus of his 911 account. The affidavit said he has not given the same explanation twice for why the body was moved.
That footage became important because Brigham Merrell told dispatchers he had found his child hanging by a coaxial cable and was performing CPR, police said. Officers wrote that when they arrived, he was kneeling near the boy but was not performing CPR. Emergency crews took over and tried to save Moroni, who was later pronounced dead at a local hospital. During those efforts, police said Brigham Merrell left the room to change clothes. Investigators described that action in the affidavit as consistent with an attempt to conceal or destroy physical evidence, though the case remains at the accusation stage.
The images from the home were later paired with medical findings that police say did not fit the hanging account. Investigators said a forensic examination found injuries inconsistent with the coaxial cable explanation. The affidavit described ligature marks that investigators believed were caused by another force, not by a hanging. It also noted bruising on Moroni’s back that appeared to have happened immediately before or during death. Police said the bruising did not appear tied to a hanging. When asked about it, Brigham Merrell allegedly said it could have been from a belt, while both parents denied knowing the cause.
The investigation also reached into what happened after the child died. Detectives said that within a week of the incident, multiple items were discarded from the home, surfaces were painted over and rooms were altered. Police did not publicly list every item or room, but they said the changes were part of the evidence reviewed in the months before the arrests. The department said detectives found inconsistencies in Brigham Merrell’s statements about who found Moroni, the child’s position and the circumstances that led to the emergency call. Those shifting accounts became part of the probable cause record.
The inquiry then widened beyond the video and physical evidence. Police interviewed children in the home and said those interviews revealed allegations of repeated abuse. One child allegedly said Moroni died after receiving a whipping from Brigham Merrell. Others described food restrictions, beatings and punishments that allegedly included being sent outside to stay in a dog run. The affidavit said belts, pans and other objects were used to whip children and that those punishments caused bruising. Investigators said video footage supported several claims made by the children.
Police also described Melinda Merrell’s alleged role through interviews and footage. The affidavit said she either directly participated in beatings or stood and watched while Brigham Merrell participated. Investigators said she told them she checked for bruises two days after a whipping so the parents could adjust methods. The documents said she discussed switching to pans because spoons were leaving marks. Police also wrote that both parents admitted to abuse and said they should have looked into Utah law before moving to the state. Melinda Merrell allegedly said she had not been taught that leaving marks on children was not acceptable.
The surviving children were referred to child welfare agencies, police said. The department has limited what it has released about them and about Moroni, citing the dignity of the victim and the privacy of children connected to the case. Some public reports identified Moroni through a fundraising page that had described his death as an unexpected passing. Police have since said the death was not accidental and that investigators gathered evidence showing an ongoing pattern of abuse. The case has drawn attention because the alleged staging happened while emergency crews were already at the door.
Brigham and Melinda Merrell were taken into custody on May 6 and booked into the Box Elder County Jail. The investigation involved multiple agencies and forensic review before police announced the arrests. The public record available from initial reports did not make clear whether the defendants had entered pleas or retained attorneys. The charges now place the evidence from the home, the medical findings and the children’s statements at the center of any court proceedings that follow.
Currently, police say the case remains focused on what happened inside the Tremonton home between the 911 call, the arrival of first responders and the later review of video from the residence. The next milestone is the movement of the criminal case through Box Elder County courts.
