The driver, whose name was not released, was described as a 10-year veteran detective of the police department. He apparently misjudged a curb as he was navigating the turn and struck it, causing the woman to be thrown from the bike. The motorcycle traveled nearly another block before coming to a stop. The officer attempted unsuccessfully to render aid to the accident victim. Police say alcohol or speed was not a suspected factor in the crash. The officer was being treated for minor injuries.
