At the time someone posted the complete timeline about the assassination’s attempt on one of the crown prince, unfortunately it was in pdf format. As usual all the public got from the government was a bunch hogwash, but never the real story. With a little luck the person with the original story, a member of Free Republic may still be around and perhaps after reading this may repost it.
