For at least one hundred years, criminals have headed to Alaska because they believed they could “hide”up here in the vastness of our Land. A number of them have been caught here because they tended to stick out like sore thumbs or we Alaskans just have more time on our hands to find out who the new neighbor is.
It is true too that Alaska (Anchorage) has attracted gang bangers from the Lower 48. Why? If you folks still had a gang unit they might be able to tell you. 
Another criminal element that sees Alaska as a place for making money off of illicit activity are the sex traffickers. Why ? A lot of lonely men up here working jobs on the Slope, military, construction, fishing, mining and other male dominated professions.
I remember back in the ‘60’s and early 70’s, they use to say there were 10 men for every one woman. 
So, I think that it is true that we tend to attract certain criminals up here.
