Who would be the "owner" of this furniture

My parents just bought a brand new house in San Clemente. There was a interior designer hired to set up furniture in the house. When we purchased the house we had the option to by the house with the furniture or bring in our own and have the interior designer return the furniture. We chose to pay for the furniture (which included TV's, kitchen appliances, couches, etc...) and make it ours. However, recently we received a phone call from the furniture shop in LA wanting the furniture back because we found out the interior designer was a Con Artist and she never fulfilled her contract with the shop. We purchased the furniture in good faith and for the proper value. The designer had a agreement to rent the furniture with the option to sell. However, she was arrested and never payed the shop the money she owed. Before she was arrested we had already paid her the thousands for the furniture. At this point, does my dad own the furniture? Or would we have to return it?
