HURON, S.D. (AP) – A Huron man is accused of brandishing a gun in an alleged case of road rage in the city. Richard Rathjen tells The Associated Press that it was a case of self-defense. Rathjen allegedly got into an altercation with another person after a traffic incident Monday, then followed that person to a job site and brandished a handgun. Rathjen tells the AP that he did have a gun but that he did not point it at the other person or threaten the person. Rathjen says he felt threatened and was defending himself. KOKK radio reports that police seized a weapon as evidence. Rathjen is facing an aggravated assault charge.
