RedactedNarrative: The victim was kayaking with his brother in an area with strong current and rapids.  both of their kayaks started to take on water.  They both abandoned their kayaks and started swimming.  
  
  The party that reported the incident made it to shore while the victim did not and drowned.  They did not wear or have any personal floatation devices.  
  
  The most likely reason the kayaks took on water was because they were tied together at the stern in a part of the river with strong currents and large rapids.
