BISMARCK — A Bismarck man tried to strangle his girlfriend to death with a yo-yo string while she drove him to the police station so he could turn himself in on other charges, court documents allege.

The Burleigh County State’s Attorney's Office filed several charges on Wednesday against Derek Delayne Dillman, 32, including felony counts of attempted murder, aggravated assault, terrorizing and fleeing police. He is being held at the Burleigh County Jail.

The charges stem from a Tuesday morning, July 20, incident outside the Bismarck Police Department at 700 S. Ninth St., about two blocks east of Kirkwood Mall. According to a criminal complaint:

Dillman asked his girlfriend to drive him to the Bismarck Police Department so he could turn himself in on unrelated warrants. As she drove, Dillman kicked the dash and windshield while making threatening comments.

He allegedly said twice that he was going to kill her.

The woman said she ran a red light at Ninth and Arbor Avenue so she could get to the police department faster. That’s when Dillman wrapped a yo-yo string around the woman’s neck and "cinched the string in an attempt to kill her" as she drove into the parking lot of the police station.

Dillman modified the string “to be used as a garrote as he believes the string can slice off a human head,” the woman told police.

The woman broke the string and ran into the police station, while Dillman drove away in the vehicle, the criminal complaint alleged.

Police said the woman had marks around her neck.

Dillman was spotted before 2:30 p.m. Tuesday driving a mini bike on Washington Street, the complaint said. He refused police commands to stop the bike until he reached the North Dakota State Capitol grounds, according to police.

He was then taken into custody, though police said he gave officers a false name and date of birth.

Dillman has a criminal history in North Dakota that includes disorderly conduct, criminal trespass, domestic violence, making a false report to police and violation of a domestic violence protection order. In two open cases, he was charged with fleeing police, driving under suspension and reckless endangerment.
