It could be negligent homicide. He may have been reckless in unholstering his weapon and pointing it at the driver's side door "just in case" and he accidentally pulled the trigger. She was hit in the stomach so I would really like to know whether the round went through the car door.
I read a couple of sites yesterday which stated the round went through the door.
Well then he accidentally pulled the trigger multiple times. That’s like falling on a knife 3 times. More likely the poor woman pulled one of his Muslim triggers like being outside in her PJ’s without a male relative to chaperone.
I’ve seen it reported that he shot through the open window rather than the door. The abdomen shot makes it seem like it could have been through the door though.
