My question involves personal property located in the State of: Pennsylvania
My Ex and I just broke up. I contacted my landlord and explained I would not be returning as long as the other person was there. The landlord then told me the lease would be cancelled without penalty and the other party would be asked to leave. I left the house and let most of my things remain inside until the other party moved out. It was an abusive relationship. I left for less then 2 weeks and returned when my ex was in another city and my landlord had informed me that all of their stuff had been removed and assured me that they would not be returning. He stayed around while I moved out as well just in case.
When I returned my Personal Computer was gone. I have not filed a police report yet as am considering giving the other persons family a opportunity to return it. I just looked up the invoice and name is not on the billing address as I used someone else's Credit Card and payed them cash. My name and address is however on the "Ship To" Shipping Address on the Invoice. There has never been any confusion on whose computer it was as I picked it out part by part, built it myself and purchased all the items with my money.
With this discrepancy will I be able to get my computer back? I do have all the boxes everything came in including all the serial numbers. I also have receipts of some of the components inside the PC such as fans and other items that were not included in the original purchase. I also at the time of purchase registered things like the GPU and CPU, and motherboard. The computer was bought part by part all on one invoice and the cost is over $1600.
My question in short is: Does my information on the shipping address section of the invoice show proof of my ownership of this property.
Thank you very much for your answers!
