A woman who was killed late Sunday while she was riding as a passenger on a motorcycle has been identified as Gwendolyn Diaz, 45, of Mesa.
She was pronounced dead at the scene after being thrown from the motorcycle driven by Kelby Randolf, who also was injured shortly after midnight at the intersection of Broadway and Extension roads, according to police. Randolf was listed in good condition on Thursday at Scottsdale Healthcare Osborn hospital, according to a spokeswoman.
The driver of the car, Charles Cooley, 18, of Mesa, was pulling out of the parking lot of a Circle K convenience store when the crash happened, police said.
Both the woman and the driver of the motorcycle were not wearing helmets. Police said they believe drugs or alcohol may have been a factor in the crash. Toxicology reports are pending.
