What can I do if my motorcycle on my friend’s garage was taken by a company hired by my friend’s mother’s lawyer?

I had a friend who was working on my motorcycle for me. He took it apart and checked everything. I bought the parts that he told me I needed and he picked them up. Two days later my friend was killed by a drunk driver. His mother would not let me get my bike for months. I emailed her proof of ownership with the title. I was given permission to get the bike. I could not get into the garage as the door was broke. My bike sat there for about 10 months. Went there last Sunday the bike was there and the door was fixed. I made arrangements to get the bike this Sunday. Got there and my bike was gone. Her Lawyer had hired a company to clean out the garage. She said she tried to call me but my phone number had changed. What are my options?
