Man charged in vehicle-pedestrian crash pleads not guilty


A man charged with hitting a woman with his vehicle has pleaded not guilty.

Karson Arthur Demers, of Bismarck, pleaded not guilty to felony criminal vehicular injury on Monday. At Demers' preliminary hearing, a Bismarck police officer said Demers told him Chaylynn Arntz "had come out of nowhere" when he struck her with his pickup.

The crash occurred at about 10 p.m. March 22 on North Third Street just north of East Main Avenue, patrol officer Tyler Mees said Monday.

Mees said Arntz was "unresponsive," bleeding and lying in the middle of the road. She was transported to a local hospital, where she remained unconscious the following day while he wrote his report.

Ward "Buddy" Hagen, Arntz's brother, previously told the Tribune Arntz broke several bones in the collision and had a collapsed lung and internal bleeding. Mees did not know her current condition on Monday.

Mees said Demers took three field sobriety tests, which "indicated impairment under the influence of alcohol." A chemical breath test recorded Demers' blood alcohol concentration to be 0.089%. The legal limit for driving in North Dakota is 0.08%.

The speed limit on the street is 25 mph, and a witness driving behind Demers said they were driving about 20 mph, Mees said. Arntz was not in a crosswalk.

Demers has been cited at least one other time for drunken driving, court records show. In 2017, he pleaded guilty to an actual physical control citation in Grand Forks.

A jury trial has been scheduled for Sept. 11.
