I believe Fox News had it right couple weeks ago. She is probably on life support in some secret location.
Possibilities.
If alive and rehabilitating she is is probably at a physical therapist’s office under the care of the PT specialist and has a script with permitted exercises from her doctor. Private property but not a private Gym.
If alive and all healed and “working out” she would probably be working out at the Gym at the Supreme court. This would be a private gym. In this case security at the least, and more likely the clerks would be aware that she was alive.
She could be consious and at home, or consious and at the hospital. Seems like someone at the hospital, a nurse, a food service worker, or cleaning staff would leak that she is at the hospital.
She has a daughter in New York (Where I think she had her operation) and a son in Chicago. If she is unconsious I would think that one of her children would have her Medical POA and she would be in a hospital nearby. If this is the case she would probably be in NY, maybe DC.
We have two blurry photos, RGB in transport and one supposedly of her beingn nursed in a comatose state, and an RGB working out in a gym sighting.
RGB moving into a car seems credible and likely. Coma Ruthie is possible, but not credible. PT rehab RGB is possible, RGB working out does not seem credible. If at SC, Workout Ruthie would probably be reported by SC denizens.
