Here's some more information that makes the claim in regards to that track suspicious. Some of these are minor, but still valid.
BFRO Report linked above from Stan says the incident happened June 14, 2003
Their web site says June 15, 2003
Only 1 day difference but at least gives us an idea of which part of June it allegedly took place.

I know when the witness returned from his hike in the rain that the track had deteriorated.

We have to walk about 2 hours back to parking lot before dark and heavy rain on that night. Creek flooded and the footprint gone.
The BFRO Report supports what Stan said, and is based on the information from the witnesses. So according to this information there was a heavy rain that night that allegedly flooded the creek that washed away the footprint. The ground was muddy where the footprint was created so evidently there was a recent rain, or at least not in the too distant past. Weather patterns travel predominantly West to East. In Sterling, IL there is a National Weather Service recording station. Sterling, IL is located approximately 18 miles West of Franklin Creek State Park where the footprint was allegedly found. The data from June of 2003 is accessible online from the National Weather Service, and this includes precipitation amounts. So if there was a rain hard enough to flood the creek that would wash away that footprint, there would be a record of it. Since we only know an approximate date of either June 14 or June 15, 2003 I'll cover from June 10th to June 20th to see if enough rain fell to flood the creek to wash away the track. Here are the totals by day.
June 10th 2003 .23 inch (Less than a quarter of an inch)
June 11th 2003 No Rain
June 12th 2003 No Rain
June 13th 2003 No Rain
June 14th 2003 No Rain
June 15th 2003 No Rain
June 16th 2003 No Rain
June 17th 2003 No Rain
June 18th 2003 .19 inch (Less than a fifth of an inch)
June 19th 2003 No Rain
June 20th 2003 No Rain
According to this data, there wasn't a significant rainfall to cause any creek to flood and wash away a track.
Here's a screen shot to show the data is from June 2003 and there was no rainfall on June 20th, 2003.

The RED CIRCLED city to the west is where the above data came from. To verify this information is most likely correct, I also checked the rainfall data from 3 area airports, circled in PINK on the map. On June 14 and June 15, 2003 not one of these sites reported any precipitation. If there had been significant rainfall to flood a creek and wash away a footprint at least ONE of those locations would have reported some precipitation. Since none did, again I say suspicious. The facts just don't back up the data reported to the investigator by the witnesses.
