Ask around and see what you can find out!
I have not been able to find any official obituary for Hilton, as of yet.
I would hate to have been the victim of a hoax and to be spreading false news.
Please let us know what you can, when you can.
I will keep looking for further information, too.
The sources I have received this news from (apart from the facebook pages) should be reliable; but, they may have fallen victim to the same misinformation, if in fact Hilton is not dead.
