She deserves to be charged with involuntary manslaughter.
There is never a sane reason to leave another person bound and gagged in any situation that could bring harm to that person, when you are in a position of control over that person!
I was going to comment on the title of the article, because it is misleading, after reading the article.
The man did not die with the clamps on him, he died and she put them on him to try to make him react.
There are not many more painful ways to make a person react, than clamps....
I know of a few, but for the well-being of all, I will not go there.:D
Silly effing me!
I would have tried something fracked up and wierd like CPR.
