RedactedNarrative: On 9/11/16 at approximately 1400 hours agents were notified of a boat incident which had occurred in Assumption Parish. Agents were advised that EMS and Acadian Ambulance had responded to the new boat launch along Highway 398 and was administering medical attention to a 7 year old female (Victim1). Upon agents arrival the subject had been transported to Teche Regional Medical Center in Morgan City. Agents also noted that the two vessels involved were at the landing. After speaking with the operators and passengers it is believed that Vessel 1 was traveling South in Bayou Cheramie when it was met by Vessel 2, traveling North, in a starboard turn. When the vessels met, Vessel 1 turned to port and Vessel 2 turned to starboard as Vessel 2 decreased its throttle. At this time the bow elevated on Vessel 2 allowing Vessel 1 to impact Vessel 2's undercarriage towards the bow. When Vessel 1 impacted Vessel 2, Victim1 was impacted between Vessel 1's console and the keel of Vessel 2 at which time she sustained fatal injuries. The operator of Vessel 1 was also struck by Vessel 2's keel on his right shoulder and arm area. He also received treatment at the Teche Regional for a contusion along with minor cuts. The 3 passengers in Vessel 1, this is including Victim1, were wearing their PFD's at the time of the incident. The operators of both vessels were not wearing PFD's at the time of the incident. Alcohol or drugs are not a factor in this incident. The operators voluntarily submitted proper breathe samples, both resulting in .000g%. The specific location of the incident was unable to be determined therefore no citations were issued.
