Pharr authorities investigating cause of tractor-trailer fire
Pharr officials are investigating why a tractor-trailer went up in flames Thursday morning.

The driver escaped from the vehicle safely without any injuries.
Pharr firefighters quickly put out the flames as Pharr police rerouted traffic in the area.
