St. Louis – A Collinsville man is expected to face charges Wednesday for causing a serious accident in St. Louis County, then leaving the scene.
The accident happened last Wednesday on Interstate 270. Missouri state troopers arrested the 53-year-old suspect Tuesday night, and he is being held in the St. Louis County jail.
The wreck happened when a tractor-trailer clipped a car, leading to a chain reaction of collisions and some injuries.
The truck driver stopped, then drove away.
Troopers say a witness took down the truck's license plate number.
Authorities are not publicly identifying the man.
