Kind of grotesque question, but, does anyone know how long it would take a human skull to decomp all the flesh and tissue (basically just leaving bone) if-there was no animal interference? I realize out in the forest there most definitely were animals helping the decomp process; but I was just wondering about telling the length of time that bone might have been out there. If they can tell it has been out there at least 3 years, I would think that might help in identifying/or eliminating a missing person who ha been gone less time than Holly. Just a random thought I had. Thanks for any help.
