After Sundance posted the exact location, I re-watched the video of the new witness, Paul K. That old tree really stands out! I listened carefully, and he said that a bridge of old tires is the only access to the railroad tracks. So, any searchers should look for those old tires. When Paul indicated the well-dressed man fishing, he pointed to the bridge on Boggy Creek Road, not the railroad bridge.
The reporter states that the media reported the previous sighting by a woman, of a white Pontiac Sunbird parked in the median, and she thought it was her friend's car, until she got closer and saw that this car had a bumper sticker where her friend's car didn't. In that report, the young woman was coming out of the woods and was wearing athletic clothing and a baseball hat.
The sighting by the woman was reported in the media on October 2nd, and the reporter said that this new witness's sighting was in the same time frame and same area.
I remember that the woman who was the subject of the Oct. 2nd report, stated that her sighting took place sometime between June 21 and 28. That was the closest she could remember - during that week. Evidently this new witness's sighting was within the same time frame.
