A woman being transferred from one hospital to its main facility for observation died after the ambulance she was in overturned early Wednesday, police said.
Carolyn Koch, 66, was pronounced dead at the scene from head trauma.
She was being taken for observation to St. Anthony’s main hospital when the driver veered off Interstate 44 for an unknown reason around 12:30 a.m. The lumbering vehicle slid and rolled, separating and completely destroying the rear compartment.
The driver, Matthew Erickson, and Chelsea Stewart, a paramedic, were also in the ambulance. They were taken to OU Medical Center, where they are in good condition.
The driver may have been speeding, police told NewsOK.
The cause of the wreck is still under investigation.
