How about this:
Chop the head off, and pull all the teeth out. Bury the head in a remote location. This should be much easier than burying an entire body. Undress the body, dismember it, and drop the pieces at various locations. It should only take a week or two for the remains to be rendered unrecognizable. Dump all clothes and blood stained utensils in a dumpster. Throw the teeth out along the highway.
LOL, even being very creepy, i really think this could work. You only have to do it right, and i think no one will ever know what happened
About someone that mentioned him in Brazil. Yes, the US have some kind of agreenment with extradition (sp?). But yeah, if Craig had some money with him, and was smart enough to make a new identity, or at least not doing anything stupid like buying something with his credit card , yeah he can hide here. If he went to places outside the major cities, he would never be found, thats just a fact . I live here and i know this for sure.
