This is nuts. I also read she had a child with her.
I first thought, maybe this person was sick and went unconscious and wrecked. Perhaps an epileptic seizure or something.
But then I read she had a gun and was firing shots. Ok, WTF. Who would do something like this with a child in the car? What a ****ing moron.
I can't believe somebody would do this to their own kid, assuming she is the mother. At least leave your kid at home if you're planning on killing people, including yourself. WTF is wrong with people.
