On February 6, 2026, emergency responders in West Valley City, Utah, rushed to the Pinnacle Highbury apartment complex garage near 2730 South High Park Way after a 911 call reported three unresponsive men inside a parked van. The vehicle had been left running in the enclosed space, leading to fatal carbon monoxide buildup. Despite immediate medical efforts, all three individuals were pronounced dead at the scene from poisoning.
West Valley City Police Department officers quickly determined the incident involved a transportation van for adults with disabilities. The driver, 25-year-old Isaiah Pulu, who placed the emergency call, became the focus of the investigation. Authorities confirmed the van’s engine had run for several hours in the garage, allowing exhaust fumes to accumulate dangerously.
According to police affidavits, Pulu had been transporting the men from their group homes to assisted living facilities that morning. Around 10 a.m., he parked the van in his apartment complex garage, claiming one passenger was agitated and aggressive. He left the men inside with the engine running, garage door initially open, and windows down, then went into his residence for an extended period.
Pulu told investigators he returned about 1:30 p.m. to find the garage door closed, the vehicle turned off, and the three men unresponsive. Toxicology reports later confirmed carbon monoxide poisoning as the cause of death for 25-year-old Colton Moser, 22-year-old Mosa’ati Moa, and 39-year-old Tim Jones, all residents of separate assisted living facilities in the area.
Following the investigation, authorities arrested Pulu on three counts of manslaughter and three counts of aggravated abuse of a vulnerable adult. He was booked into jail without bail as prosecutors alleged reckless negligence in leaving the vulnerable passengers unattended in a hazardous situation. The case highlighted risks in transportation services for individuals with disabilities.
The tragedy has prompted scrutiny of safety protocols for such services in West Valley City, with advocacy groups calling for stricter oversight. The community mourns the loss of the three men, whose deaths underscore the lethal dangers of carbon monoxide in confined spaces.
