I let a neighbor use my walker & she was evicted. How do I get my walker back

My neighbor needed a walker to use because she left her walker at the UW Hospital. She was allowed t use mine until she got hers from the hospital. Her niece came and got her upon the eviction. She left without asking if she could take my walker. I texted her niece who she is staying with to return the walker & they refused because they had no gas. The neighbor knew she was being evicted and I made it clear the walker was not to leave the place. I am disabled that is why I have a walker. I need my walker because there are times I need to use it myself. I live in Dodgeville, WI which is Iowa county. What can I do to get my walker back? I worry it will not be in the same condition as it was when it left. It may sound petty, but she knew it was only temporary until she got hers.
