The forensic anthropology stuff always gets me. Every TV anthropologist can tell a persons name, favorite sport, and every person they ever slept with based on a small piece of their skull.
When in reality it is often difficult to get gender and broad racial categories.
I know! And even if you could tell all that stuff, what are the chances that that one person has something unique enough in their profile to definitively ID them?
Interesting coincidence, though: the illegally-obtained-grafts-giving-recipients-diseases concept was a "ripped from the headlines" type story because a ring that was doing that (harvesting tissue and bone from bodies scheduled for cremation without families' knowledge or consent, faking records so that a 60-something year old guy who died of cancer is supposed to be a healthy 25 year old, taking tissue from bodies that had been left out for 100+ hours when less than 10 is the limit etc--complete nightmare) was busted a couple of years ago in NYC and Philadelphia.
And I know this because the Philadelphia Magazine article about the case was in the Best American True Crime Reporting 2009 book that I have and I read that article 2 days ago. weird huh?
