OAK CREEK - A Milwaukee-area woman recently made a scary discovery.
Caroline Cyganiak was going through her late husband's army memorabilia when she found four active grenades.
She immediately called the police.
The bomb squad determined the grenades were unstable, took them carefully to an open field and set them off.
"I’m sure it would have damaged that house extensively and probably injured anyone within a radius. That’s what they're meant to do. They are weapons of war. They are meant to kill with fragments,” said Oak Creek Police Chief John Edwards.
The police station received more than 40 calls from people who felt and heard the planned explosions.
