Police confirmed the find was a German Granatenwerfer from World War I. Authorities said because of the device’s age and length of time underwater, it was likely not dangerous. It will be safely stored until police explode it.
"They sent over an undercover vehicle and confirmed it was live, full, and they boxed it up, put it in a yellow bag, put it in the truck and took it out to what they called the field to detonate," Alexander told WOOD-TV.
Alexander has found some knives, but called this his first “cool find” since starting magnet fishing about a month ago.
