I fear that this is not an isolated case.
Probably not ... and it’s unfortunate ... if not downright criminal (no matter if one is dealing with “criminals” who are incarcerated).
I have someone who is incarcerated in IL for many years, and the healthcare they receive is generally abominable. The horror stories are abundant.
It’s not, but the prison run health care is not much better and in some instances, is or was arguably worse.
