There are many ways to get back at somebody who has dumped you.If she lied then it is a pretty extreme way of revenge by getting someone sent to prison for life.Deep down,she must have still loved him after-all. But then again,with her anything is possible.After-all she kept all this so-called information to herself prior to the murders,went along with it for weeks afterwards and even identified the dead bodies! What kind of woman is she? Actually I believe she could well have lied.She was that obsessed with him,maybe she really did do it so nobody else could have him!
