Source: A 67-year-old cyclist was killed Sunday after he was struck by a motorist east of town. Terry Lee Brown was riding his bicycle on Highway 90 near mile marker 326 at about 10:14 a.m. "when he was hit from behind," said Officer Raul Molina, spokesman for the Arizona Department of Public Safety. Both Brown and the 2001 Jeep station wagon that struck him were traveling west on the highway between Moson Road and the San Pedro River at the time of the incident. Fry Fire District medical personnel responded to the area and a medical transport helicopter was placed on stand by, said Paul Cimino, fire marshal for the Sierra Vista Fire Department. However, Brown, who was wearing a helmet, was pronounced dead at the scene. No charges or citations have been issued against the driver as of Monday afternoon, Molina said, though the investigation is ongoing. According to Sierra Vista Police, there have been two reported collisions involving bicyclists and motorists in Sierra Vista since August. Of these two incidents, one resulted in injury.
