That is sooooo gross. The bathtub has been hopelessly defiled. In fact, the entire building should probably be razed. It's a small blessing that the dude came out of the tub in one piece. I recall photos I've seen here at CDG of similar incidents, where the deceased fell apart completely -- meat came right off the bone like overcooked birds.
The victim is the nephew of a key personnel in the case, who died mysteriously prior to this. Then, this teen was found dead in his flat in Montreal. Coroner did highlighted certain issues which ruled out the possibility of accident.
