There was a case like this in San Diego back about 2000. A man was driving on the freeway about 2 a.m. when someone dropped a large rock or maybe a cinder block from a freeway overpass. It went through the car’s windshield and killed the man’s wife who was seated on the passenger side.
Always wondered why some overpasses have tall fences on each side. Now I think I know.
In 1970, I was riding my Norton motorcycle to work and a set of young people on an overpass dropped a fist-sized rock that hit me in the center of my chest.
It knocked the living crap out of me, but I stayed upright and tried to find an exit ahead of me to get off and go after those teens, but it was miles before I could get off the freeway and get back to that road and by the time I got there, they were long gone.
A nice anonymous way of killing someone.
