Johnny visiting Omaha a few weeks before his disappearance?? NOT A COINCIDENCE

So Johnny's father took him to visit the Air Force Base in Omaha, NE just a few weeks before his disappearance. There is close to zero chance that's a coincidence there... regarding the city of Omaha. It's also stunning how as persistent and strong as Noreen is- how was she not more aggressive when it came to her husband, the father of her child, answering a "wrong number" at 2 AM.. after a string of several suspicious calls at that time...
