A Graham man has been charged with six charges following a fatal three-vehicle collision on I-85 in Orange County Tuesday evening.

Officials with the North Carolina Highway Patrol have charged 40-year-old Robert Jason Mace, of Graham, with felony death by a motor vehicle, felony serious injury by a motor vehicle, driving while impaired, careless and reckless driving, failure to maintain lane control and improper passing.

Authorities say a passenger van driven by Mace traveling south on I-85 near mile-marker 165 traveled off the right shoulder and struck the rear of a tractor-trailer, which was stationary at the time. The van then collided with a Toyota pickup truck, which caused the Toyota to overturn.

The female passenger in the van driven by Mace died at the scene, according to law enforcement.

Authorities say the investigation shows that Mace was driving in a careless and reckless manner prior to the collision and passing other vehicles on the right emergency shoulder of I-85.

Investigators say they believe alcohol was a factor.

Additional charges could be brought against Mace as the investigation continues.

Mace and the driver of the Toyota were taken to Duke for treatment of non-life-threatening injuries.

I-85 was shut down for several hours Tuesday while the preliminary investigation was conducted.
