PRESCOTT, AZ - An investigation is under way after a man died along Interstate 17 outside a Greyhound bus overnight.
The Yavapai County Sheriff’s Office reports that around 2:45 a.m. deputies responded to north Interstate 17 near milepost 311 about a disorderly male passenger on a Greyhound bus.
When deputies arrived, they found the 53-year-old male unconscious and lying outside the bus.
Medical personnel were unable to revive the man and he died at the scene.
YCSO identified the victim Friday evening as 53-year-old Tommy Clayton of Phoenix.
Deputies interviewed the bus driver and several of the 50 passengers about what happened and were told that the bus, traveling from Phoenix with a stop planned in Flagstaff, became disabled on I-17.
YCSO says an impaired passenger began arguing with the driver and tried to assault the driver.
An off-duty Greyhound driver intervened, resulting in a physical confrontation with the man.
The man collapsed inside the bus and later died.
YCSO says it is unclear if the physical fight with the off-duty resulted in the passenger’s death or other factors are involved. An autopsy has been scheduled.
The off-duty driver was cooperative and interviewed by detectives, according to authorities.
YCSO said Friday evening that it appears the off-duty driver left the area. Detectives continue to process evidence, document witness statements and are awaiting test results.
