Prison for man who attacked deputy with rifle

Deyon Rivas-Maestas sentenced to 16 years


A Denver man was sentenced to 16 years in prison for attacking a Douglas County Sheriff's Office Deputy with an unloaded AR-15 rifle in Littleton last year.

Deyon Rivas-Maestas, 26, pleaded guilty on Feb. 5 to first-degree assault/threatening a peace officer with a weapon. His 16-year sentence was the maximum allowable under his plea agreement, according to a news release from the 18th Judicial District Attorney's Office.

The incident took place beneath a bridge along County Line Road, just east of South Santa Fe Drive, at Littleton's southern edge, on May 12, 2017.

Deputy Bradley Proulx spotted an SUV apparently disabled on the side of the road, according to a Critical Incident Team report.

A woman in the SUV, a white GMC Yukon, told Proulx that they didn't need assistance because someone was on the way to pick them up. Proulx told the occupants, a man and two women, that he'd stick around until their ride arrived. A person in a Honda soon arrived and took the two women, leaving Rivas-Maestas behind the wheel of the disabled vehicle.

In a dramatic exchange captured on the deputy's body camera and posted to YouTube, Proulx approached the car to offer to push it further off the road with his patrol vehicle. As Proulx approached the driver's side of the vehicle, Rivas-Maestas exited the vehicle and lunged at Proulx with an AR-15 rifle, barrel up, the report said.

Proulx fired a shot that hit Rivas-Maestas in the upper right arm, then another that hit the open door of the SUV. Rivas-Maestas then ran around to the front of the SUV and fell to his knees.

Investigators later found that the rifle was unloaded and had a cable lock on the trigger. Proulx was not injured.

“This case was outrageous,” said District Attorney George Brauchler. “We are lucky neither the public nor the deputy was injured. Given the quick reaction of the well-trained deputy, Rivas-Maestas is lucky he isn't dead. The message is clear: Attack one of our guardians, and the best for which you can hope is to go to prison.”
