No Ricin for Me, Thank You

I just watched a really shocking episode of Diagnosis: Unknown on Discovery Health. A man ("Mike") kept getting sick and his doctors didn't know why. This happens when he goes home, it stops when he goes to the hospital, so on and so forth for a while. Then, one day, he finds some Castor bean seeds and Chemotherapy medicine in his wife's bag. It turned out that she was poisoning him with those seeds, which contain Ricin, a very potent plant toxin. Not only did she try to kill him, she set fire to their house after he moved out (they were going through a divorce) and killed 2 of their 3 kids! Now if that's not a crazy story, I don't know what is.
