A man was killed Friday night in a six-vehicle crash in northeast Houston and three others were transported to the hospital in unknown condition, police said.

Officials were investigating whether alcohol was a factor when a white pickup truck slammed into two cars stopped at a red light at the intersection of Bringhurst Street and Liberty Road around 10:30 p.m.

The pickup truck's two male passengers were ejected from the vehicle, said Houston police Sgt. Regina Gonzales. The passenger died at the scene, Metro Video reported, and the driver was transported to the hospital.

Witnesses said the truck was driving "at a high rate of speed," Gonzales said.

The impact of the truck sent one of the stopped cars into another oncoming pickup truck, while a separate car traveling south on Bringhurst clipped the back of the white pickup truck, Metro Video reported.

Members of the Harris County District Attorney's Office were at the scene Friday, according to Gonzales.
