Someone Knows!

Some-one has got to know something about what happend to my mum and WHY.
How can someone keep something like this bottled up for almost 11 years?
To anyone who does know anything think about this a harmless 25 year old woman who had her all life ahead of her had it taken away for some sick reason in a most herric way why would you protect someone who could do that? WHY?
Hopefully anyone who does know anythink no matter how small it is will come forward nothing is too small, and everything will help with putting the evil twisted person away the person has already had 11 years of freedom they dont deserve anymore.
