The identity of the body as Robert is a certainty. Dental records would seem to be a formality for the prosecution and to meet legal requirements of the Coroner's office. Based on the unconfirmed report of "anchor marks", the place of death is not likely at the canal and the cause of death is not likely to be drowning. It's possible he floated down the canal, it's quite a bit larger than a typical irrigation canal, more like a river in some areas. So now the "real" investigation begins. Up until now, it's been more about collecting hard evidence from what I can tell. Oddly enough, I'm kind of hoping there are anchor marks to disprove any claims he fell into the canal. Based on the unconfirmed reports of blood in different locations, the autopsy should reveal those injuries and it seems unlikely that...WHOA! I just noticed that Wallis started to say murder and caught himself. Check out the Wallis interview, I just saw it on NG. When he says "whatever I can do to help in this mur..." and then he switches to something about helping finding Robert. I don't have a link. Anyone? It was the interview where he seemed nervous.
