I am from the area in Gwinnett county and although I did not know Kelly personally, it hits home. Me and my family spend majority of summers on Lake Lanier. Personally, I have always felt that the girlfriend knew more then she was telling. It was confirmed for me in the dissapeared episode because of all the contradictions. If she heard him turn off his xbox, then why was it still on in the morning? Also, the way she was being so specific with details(his blanket was here, his controller was here) made it seem to me that she thought alot about her story and what to say to everyone. One of 3 scenarios seem likley to me...1 being the cold medicine theory that he was disoriented and didnt know what was going on. Taking too much cold medicine (Robotussin, cordecedin) and hallucinating is actually a thing that kids do recreationally in this area, so for it to happen accidentally seems possible.Kelly's girlfriend was involved or knows something. Was she cheating, were they fighting, did she kill him or he kill himself because of that? Were they doing drugs together secretly and he went out to meet his dealer (would explain why he brought the gun) and 3rd...My friends dad knows Kelly's dad Alan, and he said Alan told him that Kelly was to testify in an upcoming murder trial. I do not know if there is any truth to that because I haven't heard it from him myself. It could be one of the many rumors going around. As for him being seen on surveillance at the gas station at 4am, that's just completely mind boggling. I cannot fathom the suicide theory. No one gets that pissed off at thier video game and then decides to shoot himself. If he was having issues in his life that no one knew about, that makes the drug scenario all the more likely. Trust me, there is alot of drugs in the area.
