Diabolical Act: Murder of Superintendent Dunn

Diabolical Act.–We learn, by a private letter from Harper’s Ferry, Va. that while Col. Dunn, the superintendent of the U. States armory at that place, was sitting alone in his office on Friday last, a young man by the name of Cox, about 21 years of age, entered the room with a loaded musket, took deliberate aim at the Colonel, and shot him through the heart. He died instantly. Cox then left the building, and made preparation to escape. He was, however, arrested, and committed to jail. We do not know what could have instigated the wretch to the perpetration of such a crime, unless a desire of vengeance for having been dismissed from employment at the armory.
