Justice for a murdered mum and nan

My mum who was a grandmother of 7 and a mother of eight was murdered on my little sisters doorstep infront of her ...over sauce on a motorbike and long hauled fued and bullying of my younger sister!! She was stabbed to death in broad daylight and headbutted on the way down!!
My little sister had to watch her best friend and loving mum blead to death infront of her helpless eyes wilst they also threatened her life also
We had to kiss her cold face goodbye as she lay in the mourge with cuts and bruises on her fragile blue face wilst we shook in distraught into why our mother was taken in such a cruel cold way !!
Not only did we have the shock of her murder but we had to watch the sniggers and the laughs from the gassman family who murdered wilst we held hand and stood trial for justice.... we got it .. life one got and 12 years the other...
We could finally say "justice for mum "
We could start our grieving !!!
Most of us struggle with ptds due to the cctv we had to watch and seeing our mum so badly decomposed after an 8 week wait for her body due to autopsys due to not admitting murder !!!
The pain starts again... they have asked for a retrial a lesser sentence
Please help us keep these monsters off the streets... and stop another innocent life being taken
Help us maintain there murder charge
Pls help and sign and put a stop to murderers coming out before there time .
Even though no time will ever bring back our mum nan sister ect
Do your crime and admit to the murder of our mum !!
