The car got stuck in a mixture of mud and snow. During the effort to get the car unstuck there was a spark inside of the car on the drivers side. The occupants of the car exited the car and found that there were flames shooting out from underneath the front of the vehicle. They were unable to stop the fire at that point and the car has been burned to nothing. I feel that there needs to be some kind of investigation as to why the car started on fire especially when it was stuck mostly in snow.
