  I first interviewed three people. I was advised by all 3 that Operator was the owner/operator of the boat at the time of the crash and they were leaving the Play Pen to go back to Diversey Harbor before striking the breakwall. No boat information could be confirmed at this time. CPO and I video and audio recorded the interview with Operator at the hospital, read him miranda. Operator''s attorney was present and he did not make a statement. I read Operator the Traffic Crash Warning to Motorist and provided him with a copy. I advised him of his requirement of filing a Boat Accident Report and advised where the form can be located.
