RedactedNarrative: During my patrol I heard the Dinwiddie County dispatcher dispatch Fire and EMS to Picture Lake for an over turned boat with a male in the water. While I was enroute I contacted Dinwiddie and they advised that the male was out of the water and the boat sank. 
  
  When I arrived and started my investigation, I met with subject. Subject stated he was notified by the front desk for the campground of the situation. He then took his kayak out onto the lake to pull the victim to shore. Subject paddled out to the victim and told him to hold on to the back of the kayak and he could paddle him to the bank. Once out of the water Victim was taken into EMS care and received advanced life support treatment and covered with blankets for warmth. I was able to speak with Victim before he was transported. He was then transported to Southside Hospital in Petersburg, VA.
  
  I also spoke to one other witness to the incident.Witness stated he was fishing with his two sons when he saw the boat tip to the right side and the male fell in the water and the boat sank. He stated Victim (Victim) called out to him saying he was not going to be able to swim to the back. Witness told him to swim back to the boat and stay with the boat and he was sending his son to get help. Victim was able to hold on to only a small portion of the stern that was not submerged until help arrived. 
  
  Investigation
  Once Victim was transported to the hospital, I took a kayak and went onto the water to take photographs of the sunken boat and to capture my GPS readings.  The following day I returned to the scene. The small Jon boat was recovered by two fishermen who had a larger boat. The victim's boat was placed on the bank and secured. I then took photos of the small 11.5ft aluminum Jon boat. 
  
  During my inspection of the boat I discovered what caused the incident. Victim had tied a piece of concrete with a rope for an anchor. The rope was tied to the stern of the boat. Victim had been fishing one area for several hours and decided to try another area. Victim was sitting at the stern and started pulling on the anchor rope. Then all of a sudden, the boat tipped and started taking on water. With the combination of Victim's weight, the concrete anchor being tied to the starboard side of the stern, and a low freeboard boat the boat quickly took on large amounts of water causing it to sink. 
  
  The boat didn't have any type of motor or engine attached to the vessel. When I interviewed Victim days later he stated he had just purchased the boat several weeks ago from a man in Richmond for fifty dollars. During the interview Victim stated he pulled on the anchor rope and pulled it up and down to clean off the mud when at once the boat was sinking, he said it happen so fast he didn't know what had happened. Victim was released from the hospital a couple hours later that same evening. Victim was suffering from hypothermia.
