Two hospitals have lost/misplaced my personal possesstions. Is there something I can legally do?

Two hospitals, one local and one state, have completely lost my mother's possessions while she is being mentally evaluated. One person has blamed it on her mental state while the others have admitted fault. Her possessions have been missing for 5 days. Every time I call, I have to restate the issue because not everyone I've spoken to has communicated the problem to the staff. I'm incredibly frustrated. My relationship with my mom has been rocky and this situation has made things worse. I want a solution and I feel like I'm being ignored.
