In the scene in the locker room with the footprints, watch the bloody prints. When they first show the prints, the toe on the right print is missing, as it should be, since the body shown in the morgue was missing the toe on the right foot. When Jim brings Melinda in to show her, he tells her verbally that the middle toe is missing on the right foot, but when they show his finger pointing at the print, it's actually the left footprint.
