That's a good point, actually. The police explicitly stated that they could find no reason for Toni to be in Parkville. So either they were lying, or they didn't know she was playing Pokemon Go, if that turns out to be the case.
If that does turn out to be the case, it will be pretty amazing that they overlooked it. I wonder if they might find that embarrassing and not release the info? It will be national news, so potentially. But I expect them to do the right thing. It seems to me to be the sort of thing that they should tell the Andersons as soon as they know.
