Whats this about teeth marks on foam?
It was one of the things found on the search. Mentioned here: http://www.riehlworldview.com/
"Also found at that location was a piece of foam reported to have indentations one could interpret to be the impressions of human teeth and the item in the picture on left - a security guard shirt with the initials VGB."
"One tragic result that has occurred from this in the past is that the unprofessional can actually place something, a bit of foam, for example, in the mouth which results in the person drowning on their own vomit - should it occur - or simply suffocating."
