RedactedNarrative: On 5/3/14 at approximately 6pm Sr. Agent and I, Sgt., were notified of a boat incident which had occurred in Lake Verrett, Assumption Parish. We were advised that a personal watercraft, PWC, had collided with a pier and one subject could not feel his legs. Upon our arrival on the scene, after speaking with the operator learned that Operator was performing 360 degree turns when he ejected his passenger from his vessel. Victim then struck the PWC with his side and could not move his legs. Victim was transported to Thibodaux Regional Medical Hospital via Acadian Ambulance. Upon contact with Operator I noticed his eyes were very glassy and red. I asked him if he had been drinking and he said no.I then performed HGN noticed several clues. He was then transported to the Assumption Parish Detention center where additional field sobriety was performed and where Operator could submit to a chemical breath test, which he did with the results being .110g%. The subjects were wearing PFD's and the operator was wearing his kill switch at the time of the incident. Alcohol was a factor in this incident, however drugs do not appear to be.
