    "Jeckel, a Coast Guard aviation electronics technician stationed in Clearwater until he was discharged on March 26, has several traffic offenses in Routt County, Colo., including guilty verdicts on driving with a restricted license and driving while impaired.
    Pinellas Park police said an initial investigation supported his account of the accident.
    The report indicated Jeckel was traveling about 30 mph in a 25 mph zone. Jeckel likely will not be charged unless found to have been impaired, Forseth said."
