Apartment Complex's responsibility to replace personal property damaged by a water leak in another apartment?

A friend, who is a senior, currently lives in an senior living apartment complex in Albuquerque, New Mexico. The apartment above her flooded and heavily damaged her apartment and many of her furnishings and possessions. The apartment complex moved her into another apartment but does not intend to pay for any of the damages to her personal property. She did not possess any renter's insurance and is on a fixed income, being unable to easily replace anything she owns. What rights does she have in this case?
