Instead Ruano pulled his SUV over, got out and the two men exchanged words as Ruano identified himself as a police officer.When Zelandi questioned Ruano and asked to see his badge, Ruano proceeded to walk back towards his own car. Then came back and allegedly shoved Zelandi in the shoulder.Ruano again went back to his SUV as Zelandi walked towards his own car.Ruano jumped back into his truck, put it into drive and allegedly struck Zelandi in the lower back area and then continued to drive the SUV, with Zelandi hanging onto the front hood, for approximately 25 to 30 feet.Zelandi told police Ruano at one point slammed on his brakes and he bounced off of the SUV, suffering neck and back injuries.
