RedactedNarrative: On the afternoon of 08/14/19, Subject took her grandson, Operator, kayaking on the
  Payette river. Subject and Operator were each on their own inflatable kayaks and were floating side by side down the river. Subject and Operator were both wearing life vests and helmets at the time. As the two were floating with the river current they came to a tree that appears to have recently fallen across the river. The tree was at the water line and across the entire river. Operator came off his kayak and was trapped under the water for approximately 10 minutes. Once pulled from the tree, CPR was started immediately by grandfather. Operator was unresponsive for the next 45 minutes until he was flown by air ambulance to St. Lukes - Boise. Operator was pronounced deceased by the doctors at St. Lukes.
