It means that she has been positively identified, via dental records or DNA or fingerprints, but her body has not been claimed. I am not sure for how long the bodies are being kept, but I think there’s a chance she might be buried on Hart Island at some point. I don’t know much about that, maybe someone with more knowledge about this can chime in.
I keep track of Unclaimed Persons on NamUs and I’ll post if her profile is removed in the future. That would normally mean that her body has been claimed.
