Well, now that she is caught I think I am safe to say this.
There is an unusual flight, nicknamed the "Island Hopper" through United Airlines. It lands at the following locations, allowing passengers to get off at each location (Except Kwajalein): Marshalls, Kosrae, Pohnpei, Chuuk, and finally Guam.
As far as I recall, you do not need a passport if you have a US ID (Driver's License). It is very possible to get off at any of these stops in between. If you know what you are doing, you can catch a boat and get to an outer island fast. Effectively vanishing from any modern surveillance.
I will say, I got one heck of an ear ache going up and down so fast. If you ever take that route, make sure to have medicine to counter act ear aches.
Marshall Islands does have a no extradition in place, but that is up to the discretion of the local Government. For the record, there is no where to hide on that island.
It's roughly 30 miles wide, but no longer than a football field at it's widest point. That and it's about at sea level.
The other islands are part of what is called the Federated States of Micronesia. They do have an extradition in place. This is made up of the following islands: Chuuk (Truk), Yap, Pohnpeii, Kosrae, and a whole bunch of small islands connected to these main islands.
Interesting fact. FSM has a Free Compact of Association with the United States. They are unique, since no one else has this, not sure if that has been renewed since that was set to expire recently. They are not US citizens, so they can't vote. However, they can travel to the US and territories without a green card (not required). They can also hold US jobs, apply for a SS card, qualify for government assistance, and so forth.
That being said, if the islanders found out that your kids were presumed dead(By you), and you were expecting them to hide you. They will hide you ,
6 feet under that is.
