Now the B.S. begins

SO for those following the thread on my stolen vehicles, I have an update. This is getting very frustrating for me because I feel that I'm going to lose my vehicle and there is nothing I can do to prevent this from happening. The sheriff in North Carolina has informed me since the Duster was titled in my late wife's name that I cannot get the car back without jumping through some very big hoops. First he has told me since my wife did not leave a will that the car is considered by North Carolina law to be 1/2 mine and 1/2 my stepdaughters car. (Which she has no rights to in my eyes) and I need to file paperwork with the county courthouse to try to be named executor of her estate. Dee never left a will and even though she bought me the car in 2000 for my Birthday present for the first two years the car was titled in my name but in 2002 when we were still living in Massachusetts, we were going through some rough financial times and I was considering selling the car to help out financially. She wrote a bill of sale at that time and signed my name to it while I was working and went to the Mass DMV and had the cars ownership transferred into her name. She NEVER wanted me to sell the car no matter how rough we were going financially. The car remained in her name when we left Mass for NC in 2006. The vehicle was registered in NC until I took it off the road to work on it in 2014. The detective has informed me that my stepdaughter sold the car without a title and the person who purchased the car paid $6000 for it. So now as it sits the car is in North Carolina and I am being told the person who purchased the car can file a mechanics lien on the title and charge me for storage on the car. I do not know what to do. I feel the car is going to be taken from me. This is the only thing I had left from my wife that had any meaning to me and I trusted in my stepdaughter to take care of the vehicle until I could get it shipped to California. Well I got screwed as usual. And now I am not sure I can afford to get the car back and even if I eventually do get it returned to me, I have no where to store it. It can not be driven and I do not have the funds to ship it out to the west coast, I just am overwhelmed in this whole thing and frustrated because the detective is being a complete asshole to me and has not even charged my stepdaughter with the theft of any of these vehicles despite the overwhelming evidence he claims he has against her and her old boyfriend. I have no contact with my stepdaughter and the detective has threatened me if I try to contact her, he will end the investigation and drop the whole thing. Meanwhile he has been talking to my stepdaughter who is lying to him stating I have contacted her and she supposedly has "recordings" of me speaking to her on the phone. I have not contacted her and she is lying to the detective and the detective is being a complete asshole to me. I am the victim here and I feel as though I have no rights in this entire matter. This is very upsetting and frustrating. I honestly do not know what to do. I do not have the funds to get a lawyer to represent me in this matter and I feel like I am going to lose the only thing I have left that was of considerable meaning that ties me to my late wife.
