A woman and her husband in northeast Maryland found a live World War I bomb while digging in a flower bed.

After the startling discovery Wednesday, Kelly and Shannon Thomas, of Belair, left the round where they found it and called the Harford County Sheriff’s Office.

“After examining the device, it was determined that the best course of action was to conduct an emergency disposal to render the ordnance safe,” the Maryland Office of the State Fire Marshal said Thursday in a news release. “Bomb Technicians disposed of the potentially dangerous round on the scene.”

“Unexploded military ordnance in the Bay and surrounding waters occasionally makes its way to the surface,” the news release said. “However, the discovery of military ordnance is not limited to tidal waters.”
