RedactedNarrative: On Sunday July 28th 2013 at about 1423 hours I was dispatched to an area north of Bartlett Lake Marina (approx. 1/2 mile), reference a pontoon boat which had a swimmer jump into the water and never resurfaced. Upon my arrival to the area which was located directly east of the Rattlesnake cove area of Bartlett Lake on the east shoreline I located a pontoon boat which had one male subject (operator) and three small girls. He related to me that his best friend had jumped off the back of the boat to swim and he turned around to drop the anchor for the girls to begin swimming. He turned around and observed that his friend was no longer visible and possibly went under. He immediately began to searching the area and called 911 while searching along the shoreline when I arrived. 
  
  Due to the emotional state of the three young girls, ages 7-9, on board the pontoon boat, I had my partner board the watercraft to console them while I had Operator take his boat and position it in the same location and direction as it was when the friend had jumped off the rear of the boat. After the approximate location was made. I obtained a G.P.S. location and set at buoy out to mark it. Volunteer then stayed on board with them and I directed them to the Sheriff''s Office Aid Station.
  
  While on scene FOX 1 (Sheriff''s Office Helicopter) also checked the surrounding area and shoreline for any chance that the victim my have made it to shore. However with negative results with their search I returned to the Sheriff''s Aid Station and spoke with Operator. Operator was able to tell me that his best friend was 44 yrs old, and had little swimming ability. He went on to tell me that he only was wearing his black swim trunks. I had Operator remain with his daughter and Victim''s two daughters while I and Sgt. coordinated the assembly of the MCSO Dive Team to make recovery of Victim. Detective was called to the scene and I turned over the remaining investigation to him while I and Sgt continued with recovery efforts. 
  
  The body was found and recovered.
