I remember that story. It was a made for TV special with Farrah Fawcett and that guy with a mustache bigger than him, can't remember his name but he was on Lonesome Dove??
Murder in Texas (1981) with Sam Elliott as Dr. Hill. He laced her pastries with crapola and when she was very sick, gave her a hypo filled with poop to speed things up.
Sick, sick puppy.
There were at least 2 books written about the case -- maybe more. The 2nd wife (who barely escaped death) wrote one of them. Hers was very romanticized.
My son went to high school with the son whose nickname was "Boot" Hill -- strangely irony, the name. He went to college in Switzerland to get away from all the trials. It was a very sad case.
There were probably more than one TV special about it. I think the one with Farrah Fawcett was based on the 2nd wife's book which was not as comprehensive as the main book. I wish I could remember the names of the books. I just recently gave one of them away.
My pint in dredging this all up is that this attack is no small matter! A lot of people could be affected.
