It's been a long time since I visited this sub, but since I just researched the Disappeared episode I had some thoughts...
* someone above asked why there wasn't blood on the dock: If he stood on the edge and fell backwards then there probably wouldn't have been any blood (or very little). It would've gone in the water.
* Jessica offering up the information about the gun and downstairs door: in the interviews I've seen it was Alan, his dad, that brought the gun up. Someone in your house is missing, you own a gun, and your door is standing open. Seems logical to look for the gun-especially if you think that someone may have been creeping around.
* Jessica scrubbing her SM pages and dating someone new 4 months later: this doesn't surprise me. People grieve differently. Personally, I like having the reminders around. Some people don't. IS there a "good" time to move on? I don't think there's a magic number. My neighbor was married for 45 years. When his wife died suddenly last year he was dating again within 2 months. For some people that's how they cope. Others just can't be alone.
* how the family and g/f acted in early interviews (detached, matter of fact, etc): Thank God nobody was videotaping me in the early days and weeks of my son's sudden death...When something like this happens biology can often take over. You're full of adrenalin. Some immediately break down and cry nonstop. Others don't cry at all and look perfectly composed. Neither response is wrong. In fact, many of us didn't feel the full impact of the loss until months later (I call this the "6th month meltdown"). Unfortunately, that's around the same time that most of the people around you begin to move on. I had zero control of my emotions. I wanted to cry. I couldn't. That came much later.
* Kelly walking so far to kill himself: people commit suicide in strange places. Cold, rainy, windy...none of those things would matter if you're planning on suicide.
* lack of bullet hole/hole in back of head: this is all based on online speculation. No officials or family have ever stated that they didn't see a bullet hole in the front of his head. However, as a hunter I can say that sometimes the entrance wound IS very small. It's the exit wound that would've had the most noticeable tissue damage. His body had been in the water for a month. That's gotta mess with tissue, too.
I do wonder if he'd felt so bad that he'd mixed cold medicines or taken too much. Our bodies are different. I'm 4'10", weigh 105lbs, and can take enough Benadryl to bring down a horse. My 6'3", 210lbs husband takes 1 and starts hallucinating. It's possible that he had a lot of (legal) something and wasn't in the right frame of mind. However, it's also possible that he was hiding something, like depression, that nobody else in his life could see (or didn't want to see).
