Maybe it is because he knew she wanted a divorce. He is a control freak, so her wanting out of the marriage would "dis" him. The strangulation did not do it, but his spite did not abate.
One last rant about this monster , then I'll quit. Why did this man collect millions from a lawsuit against the doctors claiming he was suing for ''lack of physical affection''. I'm assuming that means what I think it does. Word is this man was dating other women before Terri's collaspe, after it and then soon after aquirred a live in girlfriend and two kids. It doesnt seem to me he's been without ''physical affection'' for one second!
