Melanie Mills

My partner and I have been trying for a few weeks to contact Melanie and it was only today that we learned of her death. No one contacted us, it was discovered by an obscure notice on the web written by a Kat Baker who says she was Melanie's assistant and she left no contact info. We can't locate anyone to find out what we are suppose to do about out manuscripts that were in her possession. Can anyone help us with this. I understand that her family is grieving, however it seems to me someone would be dealing with the details of her business.
