MANDAN, N.D. — A driver charged with murder in the hit-and-run death of a Mandan pedestrian has pleaded guilty and is set to be sentenced Wednesday, July 13, in Morton County District Court.

Wade Carlton Bison, 39, entered guilty pleas to felony counts of murder, leaving the scene of an accident, terrorizing and reckless endangerment. He also pleaded guilty to misdemeanor charges of criminal mischief and driving under suspension.

Bison is accused of killing 77-year-old Erwin Geigle ,of Mandan, by running him over multiple times with a white pickup truck on March 21, according to court papers.

Bison allegedly rammed Geigle into the side of All Seasons Arena next to Mandan High School. Students, teachers and parents saw this happen, and the high school went into lockdown, court papers said.

Surveillance video showed the pickup make a sharp turn and drive toward Geigle who was walking to the arena entrance, according to court papers.


A juvenile witness told authorities he saw the pickup "ram a guy against the building," before backing up and running into the man two more times, court papers said. Another juvenile witness estimated the pickup was going about 15 to 20 mph when it struck Geigle.

Court documents did not indicate whether Bison knew Geigle or had a connection to him.

Witnesses reported that the white pickup truck quickly left the arena parking lot after striking Geigle multiple times.

Police arrested Bison later that day after a vehicle pursuit. He remains in custody.
