RedactedNarrative: At approximately 1:30 p.m. on June 23, 2019, I, Ranger, heard a call over the radio that someone was doing CPR on a person at the lake. I called dispatch and they notified me of the unconscious person’s location, the main boat ramp. The unconscious person was Victim. 
  
  When I arrived, subject1 was doing CPR on Victim on the floorboard of the vessel. Subject1 was doing CPR correctly, so I let him continue. I began doing CPR once he became tired. Once Sumner Lake Fire/EMS arrived a few minutes later they attached an AED on and a breathing tube in Victim. 
  
  Victim’s daughter and Subject1 knew of no medical history aside from Victim being overweight and a heavy drinker in his past, but not recently. The first analysis of the machine advised a shock and shocked. Every analysis after did not recommend a shock and CPR was continued until Fort Sumner EMS arrived to transport Victim. Deputy arrived at approximately 1:45 p.m.  After Ft. Sumner EMS left with Victim to the Plains Regional Medical Center in Clovis, NM Deputy and I advised subject2 and Subject1 to return to their vehicles with the boat and we would meet them over there. 
  
  They stated that Victim was being pulled behind on Subject1's vessel for approximately 3 minutes on a tube until he fell off of the tube. All stated that they had gotten Victim back in the vessel and he was sitting on the seat beside the operator’s seat. Subject1 stated Victim seemed fine and was cracking jokes. Subject3 noted that he seemed out of breath.
  
  Shortly after being brought back into the vessel they said he grabbed his chest and fell onto the floorboard. 
  
  Subject1 said to Deputy that he had one drink, Victim had 3-4 drinks during that day. Deputy responded and conducted a Standard Field Sobriety Test on Subject1 since he was the vessel operator. Deputy said the SFST was negative.
