BOSTON -- A 10-year-old Cape Cod boy is the hero of the day for finding a long-lost pair of wedding rings in the toilet of his family's Chatham, Mass., home.

Cameron Delonde said he accidentally dropped his toothbrush into the toilet and when he went to fish it out, he discovered diamond rings that had been lost by a former owner 12 years before, the Boston Herald reported.

He told his firefighter dad about the discovery and, with the help of a real estate agent, the pair tracked down the daughter of the home's former owner, Mary Trainor.

Trainor said her mother passed away five years ago and she and her brother searched in vain for the family heirlooms, to no avail. She said she was thrilled to have them back and still can't believe they've been returned.

Cameron's father said he'd had a ring stolen years ago and remembered how that loss felt. He said he was determined to return the rings.
