Did She Intentionally Kill Him?

Both the defence and the prosecution admit that she killed him in the middle of some sort of mental breakdown. The only thing that this comes down is, was this an accidental death, or did she intend to kill him? That's basely it. There's some evidence here that she didn't even totally know her mind. So most of the trial, again, mind numbing tedium, is forensic experts, tell me moresera.
