Jail guards checking suspect's poop for stolen diamonds

Jewel thief suspect Ryan Penman

LEESBURG, Florida (Fox 32 News) - Investigators in Florida are checking a suspect jewel thief's poop for the evidence.

Ryan Penman was "shopping" for diamond earrings with his girlfriend at a Kay Jewelers on Thursday when he allegedly tried to pay for the diamonds with someone else's credit card, reports the Daily Commercial

When the sales clerk rejected that option, Penman allegedly handed two earrings back -- but they were fakes, police said.

Penman and his girlfriend were taken into custody and after police realized he might have swallowed the diamonds, he was X-rayed. The earrings were in his stomach, police said.

Penman is now in jail and guards are waiting for the earrings to reappear.
