The crash happened on the Eastex Freeway near Calvacade late last night.
Witnesses tell police the driver of a pickup was going at least 100 miles per hour when the vehicle ran off the road and struck a concrete pillar.
Police say a good Samaritan stopped and pulled four people out of the pickup just before it caught fire. One of them was already dead.
"The three surviving members do have signs of using alcohol this evening. As far as the driver of the vehicle, we will have to wait for the toxicology to come back from the Medical Examiner's office," said Sgt. J.R. Roberts with the Houston Police Department.
No other vehicles were involved in this crash.
