I know of a few such stories. I like the one where a 1200-pound woman was accused of homicide in the death of her niece. So the county had to remodel her house to get her out. Then they realize she wasn't fit to be put in jail, so they decide to take her to the hospital. The only thing was that she wouldn't fit in an ambulance, so they had to rent a moving van (eg., Uhaul truck). Meanwhile, they remodeled the courthouse for larger defendants to get in.

She had like 20 life-threatening conditions. Then the ME finished their autopsy and released the report. That actually proved she didn't do it. The cause listed was Shaken Baby Syndrome, not crushing or suffocation as one might assume. That would be a bit difficult for her to do when she couldn't even lift her arms. And SBS is a rather intimate cause of death, meaning that a family member or sitter would usually be responsible. So if not the aunt, then I'd look closer.

Something suspicious was that her sister and BIL disappeared when the cause of death was determined. They fled to Mexico. So I'd say one of them was guilty. Mexico honored the extradition and sent them back.

So the wrong woman was initially charged, and that turned out to be a blessing in disguise since it kept her alive and got long-standing medical issues fixed. I can't help to think she was an accessory after the fact. Like maybe being asked to take one for the team or told, "What can they do to you? They'd have to come to get you, and I don't think they could put you in jail."
