HOUSTON, Texas (KTRK) -- The I-610 North Loop has reopened after police investigated a deadly, possible DWI crash near McCarty.
The crash happened just after 1:30 a.m. Wednesday.
Houston police said the driver was traveling westbound at a high rate of speed when they lost control, hit the guard rail and flipped multiple times.
The passenger in the vehicle was thrown from the car, police said. He was pronounced dead at the scene.
Officers believe the driver will survive. They were taken to the hospital.
Investigators said they're looking into whether the driver had been drinking after smelling alcohol at the scene.
If the driver was driving while intoxicated, they could face an intoxication manslaughter charge. The district attorney's office will determine charges.
