Michael Hatfield, 54, of Lee's Summit, lost his car keys in Longview Lake on Memorial Day. The Missouri State Water Patrol said he used a garden hose to snorkel 30-feet below the surface, with a 20-pound boat anchor tied to his waist to help him reach the bottom.
The entire incident was caught on home video.
"Keys can really be replaced," he said. "At the time, I did not think about that. It was really an embarrassment."
