RedactedNarrative: On 05-24-2016 at 1901 hours, I responded to the Snake River in the area of the Broadway Bridge for a report water rescue. Dispatch was advised that a small boat had capsized near the bridge and appeared there were 4 occupants. Dispatch was advised the boat was partial submerged in the main current and that one child was trapped in the boat. Dispatch was advised that 1 other child was floating downstream with a life jacket. We were also advised that a male was floating downstream of the boat without a life jacket. Several deputies and officers were responding to the river`s edge along with several fire units. I responded to the hanger for a boat and jet skis. Several Deputies entered the water to assist the occupants from the water. A citizen, Good Samaritan1, also entered the water to assist in trying to retrieve the victims of the crash.
  
  Operator1 had stayed with the boat to trying to save the boat and said his son was trapped underneath. Operator1 was only able to hang on to the boat for a few minutes and began to float down downstream. Several Deputies along with some fire personnel were able to wrangle the boat close to the shore. A search of the closed bow was performed and a small child was located. The child, injured1, had no pulse and was not breathing. Injured1 was wearing a life jacket that was correct size and fit. Injured1 was removed from the water and transported to EIRMC for further treatment. The other male Injured2 and his son Injured3 were removed from the water downstream by deputies and fire personnel. All occupants were transported for cold water immersion and near drowning. The civilian Good Samaritan1 was also transported for cold water immersion.
  
  We were able to upright the boat enough to remove most of the water to safely tow the boat to South Tourist Park. Valley Towing was called to assist in removing the boat and transport it to the storage building. All Deputies and fire personnel was able to safely exit the water without any further incident. Photographs of the crash scene were taken and attached to the report. An initial statement was taken from Operator1 and Injured2 at the hospital by Sgt. Prudent.
  
  On 5-25-2015 at 0830 hours, I contacted Operator1 at EIRMC in the PICU. I explained to Operator1 that I was investigating the boat crash. I asked Operator1 to explain the incident. Operator1 said that he had gone down to South Tourist Park to meet with family. Operator1 said that Injured2 was a friend and had asked if he could go for a boat ride. Operator1 said that his son Injured1 and Injured2`s son Injured3was also going for the ride. Operator1 said that Injured3and Injured1 were wearing life jackets during the whole boat ride. Injured1 was wearing a type-3 life vest and Injured3 was wearing a Type-2 life vest. Operator1 said that when he goes out with the boat he likes to take extra anchors. 
  
  Operator1 said that they started upstream from South Tourist Park towards the falls near the Broadway Bridge. Operator1 said that the boat was low on gas but he carried an extra gas can. Operator1 said that they approached the falls and the boat was low on gas so he began to fill the tank. Operator1 said his boat drifting downstream bow forward. Operator1 said that at some point his "plow anchor" had gone into the water. Operator1 said that his "plow anchor" was tied off to the starboard rear cleat. Operator1 said the boat was bow down stream and the stern was facing the current. Operator1 said that boat began to take water so he engaged the motor trying to save the boat. With the motor engaged the boat took on even more water than capsized. Operator1 explained the boat turned 180 degrees so the keel was facing upstream diverting the water and the bow was the only thing exposed. Operator1 said he saw Injured2 and Injured3 exit the boat but did not see Injured1. Operator1 said he made several attempts to feel for Injured1 but was only able to hold on to the boat for so long due to the current and cold water temperature. Operator1 said that he was not wearing a life jacket at any time of the incident. Operator1 said that he was able to self rescue to the shore and needed assistance to get out of the water. Operator1 said that he was very cold but was concerned about the other occupants. Operator1 said that he observed the water personnel rescue Injured1 from the boat and load him into the ambulance.
  
  I asked Operator1 about his boating experience. Operator1 said that he has approx. 20 hours of Boat operating experience. Operator1 said that his experience is very minimal. Operator1 said that he was just trying to save the boat and was not anticipating the boat taking on that much water. Operator1 said that it happened so quickly.  
  
  I explained to Operator1 that the boat had most of its safety equipment still on board. I explained to Operator1 that I had taken the boat to a storage building for further inspection. Operator1 said that he had adult lifejackets on board but he could not get to them fast enough.
  Operator1`s son Injured1 has not regained consciousness since last night. Operator1 said that they are awaiting further tests including a MRI to check for brain activity.
  
  I am in the process getting all the boat info and measurements. The capacity plate needs evaluated for human capacity weight as there may be an issue with over loading.
  
  I am awaiting further info to determine capacity requirements.
