What can a po legally take from a apartment I shared with SO?

The daughters of my So have Po. The daughter came into apartment and tried to take everything that was in the room. She wanted to take the walker and other equipment that was in his room. These things as well as Television were not his.
What is the PO legally entitled to take from the room? She also wanted to take other household things that we shared. Before we had a fight about PO they paid his 1/2 of rent. He is probably in long term care. Neither myself or his family know how he is doing now, or where he is. He was transferred for his own safety to another place in a different state.
