WATERTOWN, N.Y. (WWNY) - Bradley Castor is taking down an old retaining wall at his Watertown home on Clay Street.
"I find all kinds of stuff when digging cans and stakes," he said.
But what he didn't expect to to find Tuesday night was an MK1 3-inch shrapnel projectile that the Army believes was manufactured between World War I and World War II.
When Castor realized the shell could be explosive, he called police, who evacuated and shut down the 500 block of Clay Street as a precaution.
"Most people in the civilian world don't really deal with these type of devices. It was precautionary just to be on the safe side. If the device did happen to explode, it could cause some damage," said Watertown Police Department Detective Lieutenant Joe Donoghue.
Neighbor Denise Bidwell said the experience was, "Scary...didn't know what to think.
Fort Drum's Explosive Ordnance Disposal unit was able to safely transport the device back to post and destroy it. No explosives or pellets were found inside.
The unit said the shell would have been used inside an artillery cannon.
As for how the device ended up there, both Castor and the Army say they don't know.
Even though the shell ended up not being a threat, Donoghue says Castor did the right thing by calling the police because you don’t really know if the old shells are dangerous or not.
