DENVER -- Felony charges were filed Tuesday against a driver involved in an accident that killed two people on E-470 Tollway last month.

The Arapahoe County District Attorney's Office said it filed six charges against Jason Benjamin Reynolds, 32, including two counts of first-degree murder, with a possible punishment of life in prison or the death penalty. The accident was the result of road rage, according to the DA's office.

"Certainly, when Mr. Reynolds got into his car, I don't think that he thought on that day that he would end up being involved in a matter that would result in charges of first-degree murder. But this is what happens when people involve themselves in aggressive driving," said Arapahoe County District Attorney Carol Chambers. "There's nothing more serious than this. People get angry and they want to act and they need to stop and think because the consequences can be devastating."

One of the things the DA took into consideration was Reynold's track record for dangerous driving. The DA said he has a history of using cars as weapons.

He has 13 traffic offenses in the last 10 years, officers said.

And on Sept. 23, the Colorado State Patrol sent him a road rage warning letter after several people reported him. Reynolds was also due in court on Dec. 14 to be sentenced for reckless driving and posession of a dangerous weapon. In that case Parker police officers said he rammed the the rear of a Honda with his truck three times -- but no one in that incident died.

These latest charges stem from an incident in which he did ultimately kill two people with his dangerous habit, police said.

On Nov. 8, investigators said Reynolds was chasing a Toyota 4-Runner when he swerved in front of the vehicle to cut him off and then slammed on his brakes.

The Toyota 4-Runner bumped 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 other drivers told the CSP that it appeared that Norman was trying to get away from Reynolds when Reynolds swerved and cut in front of him.

"What people don't realize a lot of times is when you're doing 70 or 80 mph going down the freeway, if you make contact with the rear bumper of someone else because you've been brake-checked, you can easily lose control," said CSP Jeff Goodwin.

In the arrest affidavit it 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."

Officers said that they saw Reynolds cut off another driver on Monday, Dec. 12, when they went to arrest him and they smelled marijuana on his breath.

Several troopers said the Nov. 8 crash on E-470 near Parker was the most gruesome they had ever seen.

"We did have a couple of our younger officers that had never seen anything like this crash. It was devastating to them and it took them a couple of days talking about it to get it out of their systems," said CSP Sgt. Donald Enloe.

Reynolds also faces charges of vehicular homicide and violent crime causing death in connection with the case.
