WEST VALLEY CITY, Utah — Three disabled men died from carbon monoxide poisoning Friday after they were left inside a vehicle with the engine running for several hours, authorities said, prompting the arrest of the man who was supposed to be transporting them.
The victims — Colton Moser, 25; Mosa’ati Moa, 22; and Tim Jones, 39 — were being moved between assisted living sites by a transportation company employee, according to police. The three were discovered unresponsive inside the vehicle parked inside a garage at a residence where the driver stopped during his route.
The driver, identified as 25-year-old Isaiah Pulu, was arrested on multiple charges including three counts of manslaughter and aggravated abuse of a vulnerable adult. Officials say Pulu admitted he left the car running while he went inside his home to eat and watch television, believing he would return soon.
“And when I came back, the men were not breathing,” police quoted Pulu as telling investigators, describing how he found closed garage doors and an unresponsive group hours later. Responders pronounced all three men dead at the scene.
Carbon monoxide poisoning occurs when exhaust fumes accumulate in poorly ventilated spaces and can cause victims to lose consciousness without warning. Officers emphasized the risk of leaving a running engine in an enclosed space, especially with individuals under care.
Pulu remains jailed as the police continue their investigation. The men’s families have not released statements, and police have not disclosed further details about the transport company or oversight that might have prevented the tragedy.
