On the BR-101 highway in São Miguel dos Campos, Alagoas, Brazil, a pair of guys on a motorcycle collided violently head on with an oncoming car. The accident left both of them chopped up. Driver of the car disappeared.
It would appear that it was the plastic from the motorcycle that chopped up both victims. One was sliced in half with both legs amputated, the other only lost one leg, but due to countless other internal injuries, died on the spot as well.
