CENTENNIAL, Colo. -- A motorist accused of killing two other drivers in an alleged road-rage incident pleaded not guilty Friday in Centennial.

Jason Benjamin Reynolds, 32, is charged with two counts of first-degree murder in connection with the Nov. 8 crash on the E-470 toll road in Arapahoe County.

Investigators said Reynolds was driving aggressively as he passed a Toyota 4-Runner, then cut off the driver and slammed on his brakes.

The Toyota 4-Runner bumped into Reynolds' bumper, lost control, crossed the center median and flipped into oncoming traffic, landing on top of a Ford Explorer.

The driver of the 4-Runner, Kelvin Norman, 50, of Highlands Ranch and the driver of the Ford Explorer, Greg Boss, 35, of Lone Tree, were both killed instantly.

Reynolds was not hurt in the crash. Reynolds allegedly told officers at the scene that he was upshifting his Jeep when his boot jammed the brake pedal.

But investigators said Reynolds has a history of such driving, and that he received a warning letter last September after several people reported him.

In the arrest affidavit, Colorado State Patrol troopers said, "Reynolds seemed irritated and his attitude was indifferent to the deceased drivers of the other vehicles. He did not seem upset even though we were only 100 feet from away the other vehicles and the deceased bodies."

An arrest affidavit also indicated Reynolds told a tow truck driver that Norman "got what he deserved."

Reynolds could face life in prison if convicted. His trial was set for July 24.
