Are we now guilty until proven innocent?

I have heard a few stories and read a few articles about ”Melissa Huckabee The woman arrested for the murder of little Sandra Cantu in Tracy California. The only evidence I have heard against her is that she owned the suitcase the girl was found in. Yes that may be suspicious, but if that is all the evidence is that enough to to convict her? Will this woman ever be able to get a fair trial? Aren’t we innocent until proven guilty?
If the woman is guilty I will be the first to lock her away forever, but doesn’t everyone deserve the presumption of innocence?
