Several cows were killed and injured today, September 24, 2016, when a big rig tipped over in Palmdale, California. The truck had around 160 cows on it.
Crews set up fencing around the crash scene to treat the injured. The treated and live cows were eventually loaded onto a new truck.
At this point in time, it is not known why the truck tipped, although some have suggested it was due to lean beef (and all the cows were on one side of the trailer).
