I was able to contact the owner and she was not very responsive about me buying this mare for $100. She says she put the $500 price tag on the mare to make sure people who were interested were serious and that they would take good care of her. I also asked her about putting her down and she does not want to do that either. I am going to wait a couple days and then call her again and see if maybe she has changed her mind. She also told me a deputy had been out there to check on the mare (lots of people have reported her and someone on CL also said they contacted the media) and he saw that she had a bunch a hay in the barn and so he figured things were okay. I am very frusterated, but I am going to keep trying on this one. I will let you all know when I hear more.
