A homeowner contacted the state fire marshal after being given what seemed to be an unexploded cannonball that a family member found had near the Monocacy Battlefield in Frederick, about 50 miles west of Baltimore. Officials confirmed that the explosive was live.
Bomb technicians moved the cannonball to Beaver Creek Quarry in Hagerstown, where they conducted "an emergency disposal," according to the Maryland State Fire Marshal.
