She may have gone to school, medical school, however in Texas.
Her undated photos are credited to the University of Texas at Arlington. Since she’s being described as a nurse, I think we can reasonably assume that she didn’t go to medical school.
Her clear tie to Maine is that her boyfriend is a nursing student at the University of Maine at Fort Kent. Hickox was born in New York (I don't know when she moved to Maine, but the media calls Fort Kent her 'hometown').
The boyfriend left nursing school to be with Hickox during her quarantine period. Will he quarantine himself before going back to nursing school? At least one UMFK student, Kayla Michaud, has told the press the UMFK students are concerned about the boyfriend's possible return to the school community without his own quarantine. Will the school or the State of Maine quarantine him?
