Ranger Sam Martinsen was patrolling the Outer Cove Marina on the morning of September 12th when he came upon a vehicle being driven by a man who was known not to have a valid license, as heâd received numerous warnings and three violation notices during the previous six months for the same infraction. Martinsen stopped him and was in the process of writing him another violation notice when the man began walking away and towards his boat. Martinsen ordered him to stop, but he kept going. Martinsen then attempted to stop him by getting in front of the man and placing his forearm against him. The man responded by hitting Martinsen in the face, lacerating his lower lip. He was placed under arrest with the help of park maintenance employees who were in the area. A grand jury was to hear the case yesterday.
