Witnesses observed two men in a canoe, the canoe started to rock and then capsized.  The men tried to flip the canoe upright but were unsuccessful.  One of the men swam to shore and was injured and the other man was seen struggling as if he could not swim.  He disappeared beneath the water and his body was recovered the next morning by the dive team.   6/25/13 Update : The investigator was finally able to interview the survivor.  The men were drifting and fishing on the newly purchased canoe owned by the survivor.  The deceased had been taking pictures at the rear of the canoe and perhaps he stood up to take a picture.  Survivor did not see him stand as he was facing away from him.  Survivor reached for a paddle when the canoe suddenly flipped sending both men in the water.  It is believed that the cause of this accident is a shift in weight.  There were not wearing life jackets or had any on board available to use.  Deceased had some experience operating a canoe.
