From another article I read: The fact that we have these drugs and the levels of the drugs overwhelmingly and most logically point to this being a tragic, accidental, drug-related death, Wecht told The Associated Press from his home near Pittsburgh. http://msnbc.msn.com/id/15036342
Accidental?
People in this country are murdered for pocket change. The dead kid was a potential (and in the eyes of the law,a "presumed") heir to what might prove somewhere down the road to be a 100 million dollar estate.
Given this,I wouldn't bet a single dime that there's no foul play involved here.
