Good Samaritan Killed in Crash on I-10 in Pinal County

Pinal County, Arizona: A good Samaritan died, and several others were injured in a traffic collision involving an ambulance that happened Sunday on Interstate 10 near Casa Grande.

Authorities said the incident started when the driver of an American Medical Response ambulance possibly fell asleep behind the wheel while traveling eastbound on I-10.

The ambulance appeared to lose control at milepost 185 and traveled back and forth across the roadway before rolling.

The ambulance came to rest on its wheels between the No. 2 lane and the right shoulder.

The ambulance was occupied by the male driver and a female passenger, both AMR employees.

Two good Samaritans, a man and a woman, both driving in separate cars stopped to help the ambulance occupants.

As the good Samaritans attempted to offer help, another unrelated vehicle driven by a male driver slammed into the ambulance and hit both good Samaritans. The ambulance was pushed off the highway to the right.

The male good Samaritan died at the scene.

The female good samaritan was hospitalized with unspecified injuries.

The female ambulance passenger was taken to the hospital in critical condition.

The male driver of the ambulance and the male driver of the car that hit the ambulance suffered minor injuries.

Authorities said they are investigating impairment as a factor on the part of the driver of the vehicle that struck the ambulance.
