Body found in Lake Catherine

I beleive this is setup to look like he accidently shot himself, but I don not believe that is the case. This may be a small area, but I have visited my grandma and grandpa's house on this lake and you can hear sounds from across the lake, sometimes you can make out another persons conversation. So somebody would have heard the shot if it was out on the water. Plus, how would the gun be on the boat, and a puddle of blood be on the dock. The majority would be on the boat becuase if the gun is there that had to have been where he was shot. But you couldn't know unless you did a reanactment of the crime to see if he had fallen where the gun would land. If he had to have been shot and they staged it to try and look like it was accidental. It couldn't be a suicide becuase he shot his leg, he would have shot himself in the chest or head wouldn't you think. I think somebody shot him in the leg, inside so it wasn't as loud. Then watched him die and then placed him on the dock. To float you can't have oxygen leaving your body so he had to have been dead before he entered the water or he wouldn't have been floating. But wouldn't his neighbors have seen. Where his neighbors at the house the time of the incedent? Maybe, if he had died after he was in the water; I just don't see how that would happen counsidering it was only one leg that was shot, and couldn't he have cried out to help? Leg shots will be painful I bet, but it would not have an effect so quickly to keep him from getting out of the water or screaming out for help. Plus, if he was under water before he died, it would probably take a while for him to float up becuase he most likely drowned, and the bottom of lake cathorine isn't nice. it's gooey and mucky, and I have lost shoes becuase the sink in the mess at the bottom. So he wouldn't have risen up to the top of the water, he would still be at the bottom. So he was dead before he hit the water, the neighbors must have not been home at the moment, I am not done
