A man and woman were seriously injured in a single-vehicle rollover crash on I-10 in Marana Saturday morning, authorities said.
Northwest Fire District responded to a 911 call at 8 a.m., reporting the wreck on westbound I-10, north of Marana Road, said Capt. Brian Keeley, a department spokesman.
Witnesses told police that the car "left the roadway, went into the median, crossed an empty irrigation canal and rolled at least once before it stopped on its wheels near the frontage road," Keeley said.
A passerby who witnessed the crash stopped to help, as did an off-duty Northwest firefighter who was returning home from work. They saw that two people were trapped in the car, which had caught fire, and quickly pulled the man and woman out of the burning vehicle, Keeley said.
Firefighters arrived and extinguished the fire while paramedics attended to the victims, who were transported to the hospital with serious but non-life threatening injuries, Keeley said.
Marana Police Department and the Arizona Department of Public Safety are at the scene directing traffic and investigating the cause of the crash, which is currently unknown.
