Possibly, but I was responding to his statement that LE may not have contacted him because they knew where Terri was on that day.
We don't really know whether they checked this tip out or not. I doubt if they are responding personally to each of the thousands of tips that come in.
It would be pretty surprising if two different redheaded women, driving the same colored cars as Terri and Dede, happened to be involved in Kyron's disappearance. It would also be pretty surprising if Terri and Dede were out executing and burying Kyron on June 9th in some faraway part of Oregon, especially when LE was staying at Terri's house 24/7 at the time.
I think this guy probably saw something, although I'm not sure how he saw all that unless he also pulled down the side road and stopped to watch, but his memory of the whole thing has most likely been influenced by what he has seen reported.
