Stephanie Kercher is to launch a charity in memory of her sister Meredith, who was murdered in Perugia five years ago whilst on an Italian exchange.
The charity will use the money left over from Stephanie's 'Justice for Meredith' campaign to help the families of other victims and is to be launched in the next two weeks.
"There have been so many people who have asked where they can help and donate," the 29-year-old told The Daily Star.
Stephanie used her knowledge of Italian to help her family raise money and legally represent themselves abroad during the trial.
She was recently awarded the title of 'Woman of the Year' by the Cosmopolitan magazine.
The magazine editor Louise Court said in a statement: "Since the death of her sister, Meredith, five years ago, Stephanie remains an inspiring figure of strength and support.
"Most impressive of all is her single-minded desire to ensure her sister isn’t forgotten and to make sure her personality shines through any projects she undertakes.
"A devoted daughter and sister who has shown extraordinary courage and love in the most difficult circumstances, Stephanie is fully deserving of her award ."
University of Leeds exchange student Miss Kercher, from Coulsdon in Surrey, was found dead on November 2, 2007 in her bedroom at the house in the Umbrian hilltop city she shared with Knox and others.
Her throat had been slit and her semi-naked body was partially covered by a duvet.
Amanda Knox, also studying in the town, was sentenced to 26 years' imprisonment and her Italian ex-boyfriend Raffaele Sollecito to 25, but both strenuously protested their innocence from behind bars and were acquitted on appeal in October last year.
Ivory Coast-born drifter and small-time drug dealer Rudy Guede was also jailed for the murder after being prosecuted in a separate, fast-track trial and remains in prison.
