Thanks for the information Userid.
It's pretty much what I was expecting.. Bob Ruff has stated this opinion in his podcasts on other occasions as you mentioned. His opinion is shared by some "supporters" and "nons" alike. As far as his consultation with Ryan C. goes, Ryan can "debunk" his interactions with J.B. Clark, that's fair enough, it's his word against hers, but neither he or Bob Ruff can debunk the J.C. Ballard sighting, because they simply were not there when it took place.
Besides, a fact that is often forgotten, the sworn affidavits were from three individuals and not just one. The argumentation that the Ballard sightings do not corroborate with other sightings is not valid IMO because you could just as well say the sightings from others do not corroborate with the Ballard sighting.
As long as the three people who made these statements do not recant them, they remain just as genuine as any other sighting IMO, and if they ever recant them, it does not change the fact that Hobbs is the most viable suspect, still, after 25 years.
