Can my mother sue the hospital for being raped by another patient, male, in the psyche ward.

July 29, 2013
More details to this question:
She was put in there after a dui car crash. She had a detainer due to being on probation. The rape was witnessed by her roommate and staff. My mother was heavily sedated at the time and did not wake up until she heard everyone screaming. The rape was done by another patient in her own bed of her room at night. The police came and it was documented. The hospital sent her straight to prison right after despite her treatment plan not yet being fulfilled. I believe she should have received more treatment due to the rape. She now has posttraumatic issues and is even more of a wreck since the incident. She claims to have bleeding, pain, and hemorrhaging since the rape.
