A fiery crash has severely injured 3 people. The crash happened around two this afternoon on Interstate 10 near Highway 90. A tractor trailer and commercial truck were just two of the vehicles involved in the five-car pile up. Alabama Department of Public Safety says it appears "that traffic was slowing down due to a seperate accident near Rangeline Road when two vehicles collided causing a chain reaction." One of the vehicles occupied by three people burst into flames. They were helped out of their vehicle by Dennis Denmon of Baker, FL. The driver and his two female passengers are all being treated at USAMC for severe burns. One of the women recieved third degree burns which Mobile Fire Department and ADPS say are life threatening. Denmon was driving a commercial cargo truck that was also destroyed by the fire.
