Her picture was used as part of a fake id card, in the commission of a crime. The fuzzy camera footage looked like her (from stills I've seen) and her picture was on the fake ID. Those 2 circumstantial items were, apparently, enough to have a warrant issued.
They picked her up in TN and held her for 4 months, even after:
The ND police knew the ID was fake and the person using it was not her. The ND police knew she had been in TN before, during, and after the crime.
She is still technically a suspect, even after all of this has come out.
Ok. The mistake was made by North Dakota police (and they blame AI - the AI just gave them a possible match. Whatever.).
What I still do not understand is why she spent nearly six months in a Tennessee jail. That part remains unclear and needs further explanation.
From the first time the story surfaced, for spurious reasons[1] she was booked as fugitive, and that made it so that there was "no need" for normal timeframe of hearing.
[1] The reason being that she was found in Tennessee while being searched for a crime in another state, thus allowing them to treat it as interstate fugitive from a crime scene
