The footprint above measures 18 inches long. It was reported to the Chatham, Illinois police by local resident Michael Patrick. The print had been discovered by crewmen who were replacing a pool liner on his mother’s property. The night before strange animal noises had been heard in the area that had spooked a neighbor’s German Shepherd. As yet there is no explanation for the unusually large footprint. Nor for a series of five “claw marks” found nearby.
