I could beleive this, IF the egf had not gone to the motel and cleaned out someone else's belongings, and then to have such conflicting statements from the motel manager and to LE.
Ahhh, it is mentioned that egf told Eric she was going to leave her husband, and then denies it. I think (in my opinion) this was the catalyst for Eric going to Saginaw. Perhaps egf is one of those who always needs a man, and since she has a child with Eric, a sure way to get another man on the hook right away. Could it be that hubby found out, he and Eric get into it (insert your method here) egf, while cleaning up after hubby's mess, goes to the motel to give reason why Eric will not be coming back, and get rid of his things to make it seem more plausible?
As for the Police...I would show up there, and if I got nowhere, I would find the nearest MSP post, file a complaint and see if I could get them moving on it.
