I tried googling to find a connection to the Clintons. He was a NATO rep circa 1990-1992. That puts him in Germany at the same time Wilson was in Iraq. That's 1!!
My inclination is to suspect the family. They are so quick to say that it's him and it was suicide. What I've read is that the coroner made a preliminary ID (based on what? DNA? clothing?) and they don't dispute it. That makes me think that either they are in on a fake suicide, or they decided that he wasn't dying quick enough from his health problems. This was a wealthy and powerful family. IMO, any cop worth his salt would have alarm bells going off at this.
