How can I get a Car title in Arkansas for a car I have had for 3 months. The guy who gave it to me skipped?

out. I found out it was his car he and his wife were having problems so she gave the car away. But now I find out they did not have a title to the car. They still owe money on it. But the place they got it just keeps giving me the run around. They said since I am not the one the car belongs to they will not talk to me. But I called the police and they turned in Paper work to Rogers Arkansas And Benton County Police stations and they told the car lot they had till Wednesday to get the car out of my yard now it is Friday and they refuse to come get it.So where do I stand at.
