[The hospital where they worked got wiped out.]
If that was 2013 I saw that hospital
My SIL worked in the x-ray department of the Moore Medical Center. She was off work that day because she was getting ready to retire. The pictures she sent us were dated May 2013. They were taken a few days after the tornado. Some of the debris had already been removed to clear the roads. There were still cars lodged in the building though.
