RedactedNarrative: On April 27, 2015, at approximately 9:00 p.m. it is reported that while traveling upstream in Bayou Manchac vessel LA-3689-FX began to take on water and sink. Weather conditions and visibility were extremely poor. passenger aboard vessel, states he was able to abandon the vessel and safely swim to the eastern shoreline. 
   
  On the night of the incident, river conditions and currents were extremely hazardous due to recent torrential rainfall in the area. On 4/30/15, the vessel involved was discovered semi-submerged and removed in the Amite River approximately 3 miles downstream from the incidents occurrence. On 5/1/15, Victim’s body was recovered from Bayou Manchac approximately ¾ of a mile from the incidents original occurrence. The Ascension Parish Coroner’s Office reports Victim’s preliminary findings of cause of death to be asphyxiation by drowning. 
   
  According to Victim’s family members and the sole surviving passenger the vessel was equipped with the required PFD’s, however this could not be confirmed as the vessel was discovered submerged and all items in the vessel has floated free. Investigators have no reason to believe otherwise. 
   
  Investigators have determined the primary factors which led to this incidents occurrence and Victim’s subsequent death to be as follows: 
  1&2 – Poor weather conditions and abnormally extremely strong currents (estimated between 12-15 mph) caused by torrential rains earlier in the day were a major factor. 
  3- While Victim allegedly possessed adequate experience in the operation of his vessel in this particular area under normal conditions he lacked the experience necessary in the investigators opinion to operate this type of vessel under the hazardous conditions which presented themselves on the night of this incident’s occurrence.
  Supplemental Report Dated 7/25/2015:
   
  On July 24, 2015 I, Sgt. received and reviewed the Ascension Parish Coroner’s final report and findings in relation to the cause of death of Victim in relation to a boating incident which occurred on 4/27/2015 on Bayou Manchac in Ascension Parish. Victim was the reported operator of said vessel at the time of the incidents occurrence. As expected cause of death was ruled to be “Asphyxiation By Drowning”.
   
  Toxicology results indicate that Victim’s blood alcohol at the time of examination indicated a blood alcohol concentration of .170g%. Test also indicated Victim had a measurable amount of THC at the time of testing. As the lead investigator of this incidents occurrence the final toxicology reports give me cause to revisit this incidents original cause and contributing factors.
   
  A .170g% blood alcohol concentration well exceeds the state law’s legal allowable limit for the operation of any and all motorized vessels and vehicles. Alcohol is well known to inhabit coordination, impair judgment as well reduce alertness. The combination of alcohol as well as THC only proves to enhance the alcohols overall effects of impairment when attempting to operate a motorized vessel especially when in distress.
   
  In conclusion, based on these reports, while the original factors for this incidents occurrence remain unchanged the order in which they are listed changed slightly (see below) with the addition of alcohol as a contributing factor. Victim’s state of impairment is determined to be definite contributory factor in this investigators opinion.
   
  Contributing Factors Revised:
  1- Weather
  2- Hazardous Weather
  3- Alcohol Use
  4- Operator inexperience
