Deputies and detectives interviewed the bus driver, an off-duty driver, and several passengers (about 50 on board), regarding the circumstances. Deputies learned that the Greyhound bus had stopped along I17 due to mechanical issues. While the bus was stationary, Mr. Clayton apparently impaired, from drugs or alcohol, began arguing with the driver and then attempted to assault the driver. An off-duty Greyhound driver intervened resulting in a physical confrontation with the man. The passenger collapsed inside the bus and later died.
It is unclear at this time if the confrontation with the off-duty driver resulted in the man’s death or other associated factors are involved. The body has been transferred to the Medical Examiner for a scheduled autopsy which toxicology should also reveal the nature of the impairment.
Detectives are processing evidence, documenting numerous witness statements and awaiting test results from the Medical Examiner’s autopsy expected in the next several days.
