Wow. No wonder I was confused.I believe your talking about Dr. Statheropoulos. He's Greek.In fact he was referred to as the "Greek Guy" at times because his name was difficult to pronounce.
And only one chemical in the trunk was the same?I guess I'll have to look that up, but I thought it was more.
There were more. It's not that they only found 1 ( actually 4 if you follow the link below) out of 80+ in Dr.S's study, they ruled out the majority of chemicals found in the trunk that were also in Dr. S's findings because they were not "key decomposition indicators". So after the more common chemicals found in the trunk were ruled out (common ones were included in Dr. S's 80+), they were left with 5 "select compounds of interest" taken from the trunk (Furton said 1, but that was a misrepresentation). Four of those five were "key decomposition indicators" in Dr. S's report and the fifth item was chloroform.
