An Arizona couple is facing first-degree murder charges after police say they carefully planned the killing of a registered sex offender, even scouting out a remote desert location where they intended to leave his body.
Jacob Dylan Middlebrook, 35, and his girlfriend, Layne Justine McIntosh, 36, are accused of killing 29-year-old Arron Christopher Warren, whose body was discovered along a desolate stretch of road in Bullhead City on November 7.
According to investigators, the alleged murder was no random act of violence. Detectives believe the couple targeted Warren because of his status as a registered sex offender, a detail that has raised disturbing questions about how far they allegedly went to prepare for his death.
The investigation began around 11:45 a.m. when a passing motorist spotted a man’s body beside Silver Creek Road, approximately one mile east of Bullhead Parkway. Officers arrived to find Warren suffering from multiple stab wounds.
As detectives began piecing together his final hours, they discovered that his vehicle was missing.
Investigators soon identified Middlebrook and McIntosh as suspects. Police said the couple, who were experiencing homelessness, had known Warren for several months and had previously expressed strong hostility toward registered sex offenders.
Warren was classified as a Level 2 sex offender in Arizona, a designation indicating a moderate risk of reoffending. According to previously released police records, he had been convicted of attempted sexual conduct with a minor in 2022.
But authorities say the couple’s alleged actions went far beyond expressing their dislike.
Detectives believe Middlebrook and McIntosh selected the desert location in advance, intending to abandon Warren’s body there after killing him.
In an especially unsettling detail, police allege the pair even measured discarded furniture and beds along the roadside to determine whether the objects were large enough to conceal his remains.
Authorities have not publicly explained exactly how the alleged attack unfolded or what evidence led investigators to conclude the killing was premeditated.
The investigation took a major turn just hours after Warren’s body was discovered.
At approximately 4:40 p.m., police located his missing vehicle parked at a casino in Laughlin, Nevada, just across the Arizona state line.
Working with the Las Vegas Metropolitan Police Department, investigators arrested Middlebrook and McIntosh that same afternoon.
Both were initially booked into the Clark County Detention Center on suspicion of second-degree murder. However, as detectives uncovered additional evidence suggesting the killing had been planned, authorities upgraded the charges to first-degree homicide on November 9.
Arizona court records confirm that both suspects face charges including first-degree murder. They subsequently appeared in a Nevada courtroom, where they waived their rights to extradition hearings as proceedings to return them to Mohave County moved forward.
The case has also prompted a warning from Bullhead City Police Chief Paul George, who emphasized that public information about registered sex offenders must never be used to justify violence.
The police department routinely notifies residents when Level 2 or Level 3 offenders move into their neighborhoods or change addresses. Those alerts are intended to promote public awareness and safety, not encourage residents to take the law into their own hands.
“Our goal is to provide information, not create fear or alarm,” George said.
Police also conduct monthly address verification checks to ensure registered offenders comply with reporting requirements.
While investigators believe Warren’s criminal history played a central role in the alleged murder, they have not disclosed whether any specific confrontation triggered the attack.
