Bismarck, N.D. – A 43-year-old Bismarck woman was arrested late Thursday night after a four-hour standoff with police following an alleged stabbing of her boyfriend, authorities said.

Officers were called to the area of 300 West Front Avenue at about 7:30 p.m. after receiving a report of a man walking with a significant amount of blood on his clothing. When officers contacted the man, he said he had been stabbed in the left shoulder and chest area by his girlfriend, identified as Shannon Gresham of Bismarck.

The man was taken to a local hospital for treatment and is expected to recover, according to the police department.

Officers then went to Gresham’s residence in the 400 block of Memorial Highway. Authorities said she refused to leave the apartment and was seen holding a knife. The West Dakota SWAT team was called in and responded to the scene.

Despite multiple commands to surrender, Gresham did not comply. After an arrest warrant was obtained, SWAT officers breached the front door and deployed a chemical irritant. Gresham still refused to exit, and officers made entry and took her into custody at approximately 11:40 p.m.

Police said the standoff took place in extreme cold, with wind chill temperatures below 30 degrees below zero. Officers and SWAT members maintained containment and safety at the scene for several hours until the situation was resolved.

Gresham was taken to the Burleigh Morton Detention Center and booked on charges of aggravated assault and preventing arrest.
