Five members of a family were injured Monday morning on Glassford Hill Road when the Jeep they were driving in rolled over near Tuscany Road.

Early information from the Prescott Valley police investigation indicates that the driver of the Jeep - Gregory A. Wright, 40, of Ash Fork - drove south on Glassford Hill Road tailgating a slower vehicle, and when he passed the vehicle at a high rate of speed, sideswiped it and continued speeding, police believe. He then left the roadway on the right shoulder, overcorrected into the median and overcorrected again, causing the vehicle to roll over at least twice, said Sgt. Brandon Bonney, spokesman for the Prescott Valley Police Department.

Investigators learned the driver of the vehicle that was sideswiped called 911, tried to follow Wright's Jeep and saw the crash, Bonney said.

Wright, his wife Jamie, their 7-year-old daughter, 4-year-old daughter and 3-year-old son were all injured in the collision and all had been properly restrained in the Jeep, Bonney said.

Witnesses helped the injured family members until police and emergency medical services arrived.

Kim Carlon, who was driving with her brother, helped the Wright's daughters at the scene. "They were the bravest young women I've ever met in my life," Carlon said.

Gregory Wright, whose hand was pinned under the vehicle, and his son were flown by helicopter to Flagstaff Medical Center for serious but non life-threatening injuries, while Jamie Wright and their two daughters were taken to Yavapai Regional Medical Center-East with what appeared to be non life-threatening injuries, Bonney said.

Charges are pending the outcome of the investigation, but it appears that alcohol, fatigue and speed were factors in the collision, Bonney said. Investigators obtained blood from Wright that will be analyzed. Wright may face multiple charges.
