I do not think they were in Alaska in May 2017---my opinion only---because the Jackson Days Inn Trash Pull was done on June 8 , 2017.
We know the Wagner's were gone during the Friday May 12 and Saturday May 13 searches of their former Peeble's farm property and their trailers that were stored at the car lot. They had sold their Peterson Rd. property in March and were not living on it during the searches.
So to me it makes no sense that the Wagner's would be in Alaska in May, then turn around and travel to, and be in, Jackson Ohio on June 8th, then go back to Alaska later in June. They had a conversation with an Alaskan neighbor in June so we know they were in Alaska in June.
I think they took off from Ohio in May (because the heat was on) and did their stay in the Jackson Days Inn and then did their Montana and Missouri property transactions (according to the evidence) and then ended up in Alaska sometime during the month of June.
Just my speculation from what little we have to go on from the evidence released to the media.
Wow. They are keeping an unusually tight ship, considering this case is so high profile.
Oh, and to complicate the month of May 2017 even more, there were, according to the evidence, about a dozen interviews with the Wagner's in the month of May, 2017. 99% of them were audio interviews. That means all these interviews could have been long distance, away from Ohio....
