I only saw one statement and it was supposedly from LE about a possible hitchhiker on the Hoosier Hwy. And now that I think about it, why would the killer be on the Hoosier Hwy? In one of my scenarios, he takes the wrong trail and ends up at the Freedom Bridge (this assumes the sighting around 3:00 is the killer), goes to the parking lot and crosses the Hoosier Hwy to the CPS. What if this was misquoted by media and they meant the Rt 300? (Or LE purposely gave the wrong road in order to obtain a valid witness.) GH states in his video that a witness saw someone in the area of the cemetery, but I don't remember anything like that unless it was someone not reported the media or validated by LE. In fact, I believe GH got it from a phone call about what someone read on Facebook.
Even though I strongly discount this witness sighting on the road in front of the cemetery, I believe there is a good possibility the killer went in that general direction after committing the murders. Again, an assumption here is this killer was familiar with the area. More than likely, though, I believe this killer stayed inside the treeline parallel to the road rather than going out through the cemetery. His pants are wet and this might be noticeable. There are no leaves on the trees or shrubs so visibility through the trees is good. He can minimize his chances of being sighted by staying off the road as long as possible.
If my scenario above is correct, could this be the reason for the change of direction by LE? IOW, the sightings on the trail and Freedom Bridge are not the killer. Instead it may be a person seen going to his vehicle at the CPS building and he was NOT seen on the trail AFTER the murders. Again, I'm just tossing out some random thoughts here.
