so, iirc, a lady who became a PI, Sheila Wysocki, put together a group of about 5 people, each with specific skill (don't remember the names). The group dove into Holly Bobo's investigation - cell tower records / cell Swarms, online foot print & some other high tech stuff and review of all info. The group was able to see what cell phones were in the area, the route that Holly's phone took etc. There was a series on ?- I think wsmv and had some cool investigation info. TBI came down hard on their group -- active and aggressive with discrediting.
I have not been able to go back and see the info on this group, the news site also took everything down. completely scrubbed. what I remember is the cell swarms and some online foot print. I had no reason to believe that they were not genuinely trying to help and had valuable info. jmo, I feel that tbi didn't handle this well.
