Well, I'm trying to be open-minded, but yes, my first opinion is that EA is solely responsible. As far as a dumpster...possible. Some dumpsters have a strong smell anyway and I don't know the schedule of when they are emptied. I do know that those guys that drive the big trucks to empty them, just sit inside the truck, drive up to the dumpster, stick the big forks inside the two slots, lift it up and dump the stuff into the rear. CM could have been wrapped up in a tarp or something (hate saying all of this)... So yes, she could very well be in a landfill..
My second opinion is that someone close to EA helped hide her & took her to heaven-knows-where..
