My guess is that the body is Rafe

Everyone just thinks it was Adam that did all that...I bet it was Shelia/Daisy/Ryder that set the explosion..how else would they have gotten Lauren away from Michael and others not see where she went? Adam of course will get blamed for it, but I think it was Shelia. She did tell the kids that they were going to begin now with their plan. Adam wouldn't have gone down and set the gas open...he wasn't in it to kill anyone, just escape. The body could have just been a maintenance man or someone of no concern to the others. Probably Shelia had to kill him to get to the gas pipes to make the leak.

it won't be Adam and no other men are missing, so you're probably right... But was it Adam who did the killing or was it Ryder, Daisy and Mama?

I was thinking it was Rafe as well. I cannot see someone like Adam being killed off. Adam is just trying to buy time before he gets caught. I am glad that Sharon allowed Adam to confess that Faith was her baby and not Ashleys's (as much as I dislike Ashley, I am sorry that she had miscarried because of Adam). I would not be surprised if it was Adam who killed Rafe. Rafe knew a lot and had wanted to confess what he knew, but Adam blackmailed him.
