Thank you for your response. I see your mother's problem now and why she is having an issue.
In order to be able to sue anyone she has to actually prove who is liable for her injuries. Under the extreme mass confusion you describe, it is doubtful proving anyone is liable for her injuries would be possible.
The NC courts state, In a premises liability case, the duty to exercise reasonable care "requires that the landowner not necessarily expose a lawful visitor to danger and give warning of hidden hazards of which the landowner has express or implied knowledge." Bolick v. Bon Worth, Inc., 150 N.C.App. 428, 430
, 562 S.E.2d 602, 604
, disc. review denied, 356 N.C. 297
, 570 S.E.2d 498 (2002)
Thus, where in a negligence action a plaintiff must show that the defendant had a duty to the plaintiff and that the defendant breached that duty, thereby causing the plaintiff's injuries, ... a plaintiff in a premises liability action must show that the defendant owed her a duty, and that the defendant breached that duty by unnecessarily exposing her to danger and failing to warn her of "hidden hazards of which the landowner has express or implied knowledge[,]" thereby causing her injuries." See: Cherney v. North Carolina Zoological, 657 S.E.2d 35 (N.C., 2008).
The issue your mom has is proving the hospital or the sheriff performing his lawful duties had some duty to protect your mom from this type of harm occurring in this way on their premises. As this was an emergency situation that the hospital had no forewarning over, this is where holding them liable for not warning your mother or taking better action to prevent this from happening to your mother would be almost impossible.
This is what attorneys do when clients come in with a case, they look at the facts and what the case law says you have to prove. Not every injury that takes place on the property of someone else makes the owner of that property liable for the injury according to the NC case law and I am afraid that is the conclusion the attorneys you have presented the evidence to are discovering as well. The case law above is what the NC Supreme Court states, so that is what you and the attorneys are bound by.
You are free to try to consult with some premises liability attorneys in Raleigh or Charlotte which you can find at the same sites used by other attorneys, http://www.martindale.com or http://www.hg.org, but I am afraid that based on your facts the hospital is likely not going to be able to held liable for your mom's injury.
