Heier says the 2-year-old and man were pronounced dead at the scene. He says the teen was taken a hospital, where he died during surgery.
So he/they shot to death the Dad driver and his teen kid.
My hunch if the dead driver’s teen wasn’t a passenger in the vehicle, there could be more to this story. Prior dispute at the location etc.
Whoops, it wasn’t reported the it was the driver’s teen, but a dead 15 year old teen non-passenger.
Hmmm
