RedactedNarrative: On 6/29/14 I, Sgt. , was notified of a vessel that had sunk along the Intracoastal Waterway just west of the Franklin Canal in St. Mary Parish.  the subjects involved advised that they were traveling in the Intracoastal when the transom on their vessel broke and the vessel started to take on water.  The subjects were able to make it to shore where the vessel sank.  They then secured the vessel and called 911.  there were no injuries, alcohol or drugs involved in this incident.  The subjects were wearing their PFDs at the time of the incident. The vessel was retrieved several days later and after inspection of the vessel it is clear to see that the transom failed, which caused the vessel to take on water.  there was no clear evidence of any impact which could have caused the transom to fall.
