Abused Horses

So I recently placed some horses for a woman that became terminally ill. She called me for help and I was able to place all 5 horses in great homes. Check out my rescue horses journals and photos. This woman was very concerned about a horse she had sold years earlier, that ended up abused and taken from the owner. Days before she passed, I was able to tell her I found the horse and he is now well cared for. She was thrilled. At the funeral, this woman approached me and insisted I tell her where this horse is. It was actually the woman who abused him. She had 20 horses removed from her. They found dead animals on her proerty. It was horrible. They removed dogs and sheep. This woman will never find out any info from me on any of the horses I placed, or the one she lost and is looking for. She was talking to me like she didn't know why they were removed. What can I do if this woman starts harrassing me about it? She thinks she has a right to know where the horses I placed are also. I will never tell her anything. Any suggestions if this escalates??? So far I have not heard from her, but she did get my phone # and told me that I had to give her the info. Over my dead body!
