Original Article Police official blacks out, crashes Katie Nelson The Arizona Republic May. 18, 2005 10:40 AM A Tempe Police commander blacked out and crashed his car, injuring a man waiting at a bus stop Tuesday night. Commander Mike Ringo, a 27-year-veteran of the force who helps oversee police patrol in the north part of the city, was driving north on Kyrene Road when the accident happened just before 7:30 p.m., police said. It is unclear if he was on duty.. Ringo was approaching Guadalupe Road in south Tempe when he drove a 1996 Chevy Lumina into the road's east curb. The impact deflated the right, front tire, police said. The vehicle continued north with Ringo unconscious at the wheel, according to police. It entered the Kyrene and Guadelupe roads' intersection, then jumped the curb. The car careened into a concrete parking bench and struck Michael Craig Buehler. Two of Buehler's legs were broken, and possibly his back. The 56-year-old transient also has a concussion, police said, but he is expected to survive. He is being treated at Maricopa Medical Center. Ringo was transported to Tempe St. Luke's Hospital. He received treatment for the "condition that prompted the collision," police said. He is listed in good condition. Investigators have determined Ringo's vehicle was traveling less than 40 miles an hour when the crash happened. They will continue to investigate.
