Yeah, almost certainly meth-related. There’s a lot of poor white trash out in those small towns. I grew up with them. One childhood acquaintance is in Menard doing life without parole for murdering his parents and brother and another is on death row in Florida.
It's interesting that the offensive term of "poor white trash" gets a free pass here on Free Republic. Yet there's the near universal use here of Amish as a euphemism for black thugs. And yes, I realize that Amish here on FR has morphed in meaning over the years from its initial coding of muzzies to also encompass blacks.
