(KMOV) - Friday's deadly cross-over crash in the Metro East might have been caused by a motorist cutting in front of another vehicle without warning.

News 4 talked with a driver who says he witnessed the frightening chain of events.

John Ratermann of Aviston, Illinois says he was 150 feet directly behind the red Chevy on I-64 going east bound involved in the fatal crash.

Ratermann says a silver jeep with a woman driver cut in front of the red Chevy near Green Mount Road in O'Fallon.

The silver jeep came within a foot of the red car, so the red car had to make almost a left hand turn to miss the jeep.

Ratermann says the woman in the jeep kept driving and he thinks she didn't even realize what had just happened.

The car crossed into westbound I-64 only about 100 feet from the end of a concrete median wall that stretches seven miles from I-255. 

According the Illinois Department of Transportation there's nothing remarkable about the lack of a median wall.

I-DOT says that concrete barrier was just added as part of a highway widening project that added a third lane.

The widening project however ended just before the Greenmount exit.
