RedactedNarrative: SYNOPSIS: 
  On June 4, 2015, Classic Lifeguard Helicopter reported to the Grand County Sheriff's Office that they had responded to Westwater Canyon/Funnel Falls/Colorado River, N 38 degrees 59' 38.53, W 109 degrees 09' 20.34. The actual number were (2) and the deceased were being transported to the Cisco Boat Ramp. The event that led to the death of the two subjects was (2) separate rafts that had either overturned or flipped the passengers out of the raft. The cause of death(s) was suspected to be drowning.
  
  WESTWATER CANYON/FUNNEL FALLS:
  Westwater Canyon is a section of the Colorado River that is approximately 54 river miles upriver from Moab, Utah.
  Funnel Falls is located at approximate river mile 118 and is part of an approximate 2 mile stretch of rapids that begins with Marble Canyon Rapids and ends downriver at Last Chance Rapids. Skull Rapids is one of the rapids in that series and is below (downriver) of Funnel Falls. The flow rate of the Colorado River can dictate the conditions of these rapids, with a larger flow rate minimalizing the conditions of some rapids, and a lower flow rate making the rapids more hazardous. The flow rate on 06/04/2015 per USGS shows the rate of flow at 20,000 and the temperature at about 61.5 degrees F. A search and rescue member was questioned about this stretch and stated that it was approximately a 30 minute float/paddle through that stretch depending on river conditions.
  Funnel Falls is described as a part of the canyon with large rocks on both sides that create lateral waves/rapids on both sides. I was told by the same search and rescue member that the typical approach to these lateral waves/rapids is to direct the boat/raft into the wave/rapid and have passengers "highside" the raft into the wave/rapid to place the weight into the wave/rapid. A lateral wave/rapid appears from boat operator(s) statements to have been the impetus behind the raft(s) overturning or ejecting passengers from the raft(s).
  
  Operator1:
  Operator1 was the boat operator that Victim1 was a passenger. Operator1 is employed by Sheri Griffith River Expeditions. Operator1 has a Utah State Parks and Recreation Captain/Guide License Boat Crew Permit. expiring in 2018 with endorsement: WCG. She also has course certificates in wilderness first responder, swiftwater safety institute, adult/child CPR, AED, and airway management, and food handlers permit.
  Operator1 provided a written statement as well as telling what had happened when we met at the Cisco Boat Ramp.
  Operator1 was the boat operator when the raft floated through Funnel Falls. Two people were at the front of the raft. Victim1, and two others were in the back of the raft. The raft overturned in a "right" lateral wave. Operator1 and all passengers were thrown into the current and when they surfaced they hung on to the ropes on the raft. She did a head count and only counted 4. She coached the others to hold on. They continued through the rapids until they could get to another boat. Operator1 states that she saw subject on the raft operated by subject2 and got into the and assisted with CPR. CPR was continued until they met up with medical helicopter. AED was attached at that time. Efforts were unsuccessful.
  
  The next day Operator1 provided a statement regarding safety procedures including the wearing and fit of floatation vests and what to do if they fall out or raft flips.
  Statements were obtained from the passengers on Operator1's raft, excluding Victim1. The statements are similar as to what happened including instructions from Operator1 to lean forward and punch into the wave/rapid. The direction of the capsizing is unclear with one person believing the raft flipped back to front. The passengers hung onto the raft through the rest of the rapids until they were picked up by another raft. 
  The statements do not include any information as to Victim1 and his whereabouts when they surfaced and hung onto the raft. Victim1 was not seen until they had cle
