From above article, (Thanks for finding that, Human) "They didn't notice anything or anyone unusual at the store, Larson says. "It was 9 p.m. on a Sunday night. There was not too much going on." So evidently "staring old man" wasn't there at that point?
And.. "Garber says several men emerged as suspects, but no one was charged.
"There are several people who we could not determine whether they did it or not," he says. "We did everything that we could do to determine that. We found them. We talked to them. We tried to trace their movements. We tried so many, many things, and there are several people who still ... I don't know if they did it, but I know that they could have."
I think that's kind of where we are at in our sleuthing also.
So weird about that other Jacob Wetterling contacting them. What are the odds?
