From what I've read about the case it was the fact that he got out of the car (i.e. decided not to kill himself) and she told him to get back in. She knew he wasn't fully in control of his actions because of his mental state and so telling him to get back in, whether she wanted him to die or not, was reckless. IANAL though. Any lawyers here who could explain the details of how they satisfied the elements required to prove involuntary manslaughter?
