GB read what I posted about the woman who was found guilty of manslaughter. You needn't apparently be the one that KILLS a person to be the cause of their death.
No. But you do have to know, or have reason to know, that your actions might cause their death. Telling your outraged, armed husband that a particular man raped you may be pushing it, but I can see how a jury could feel that she should have known she was putting that man's life in very serious danger.
What this woman did, though disgusting, isn't quite the same. I can't honestly say that she should have known the girl might kill herself. Oh, the idea might have crossed her mind, but teenage girls are rejected every day and the vast majority of them survive the experience. What she did was very wrong, but saying she should have known the girl would kill herself only barely passes the "giggle test." Saying, however, that she intended to inflict emotional distress, and that she was harassing, even stalking this girl . . . that flies.
