First of all, please show some class and refrain from using cuss words when addressing me, as I have done nothing to warrant such vulgarity.
Secondly, I actually hope it wasn't Burke for the simple reason that I have ALWAYS thought it was one or both of the parents.
However, the "EXPERTS" in that news special deduced beyond much doubt, IF ANY, that it had to be the brother. Most parents would cover their child's crime up, so it's not a stretch to believe that the Ramseys went through a lot of trouble to do so.
Besides that, Burke's demeanor was just too dang "LAID BACK" even though he was being asked questions about his own sister! And if he was that mentally ill, then someone besides YOU should have mentioned it while being questioned by both the authorities and the press.
