A Missouri facing first-degree murder charges after allegedly stabbing his father 50 times told authorities it was an accident, according to a criminal complaint.

Shilei Du, of Montreal, is facing first-degree murder charges after he was released on bail in September then killed his partner just weeks later.

The man's wife said he mentioned that he "wanted to die" and that he was in pain before he attempted to strangle her, which she said is something he says often.
