Harry Potter star Daniel Radcliffe has written a heart-rending message to comfort the mother of murdered actor Rob Knox.
Daniel, 19, was just one of the devastated cast and crew of Harry Potter and the Half-Blood Prince who penned moving tributes to 18-year-old knife victim Rob, reports thesun.co.uk.
Signing himself "Dan xxx", the star quoted a line from famed author D.H. Lawrence when he wrote: "The dead don't die. They look on and help."
Daniel wrote: "Dear Rob, We are all proud to have known you and devastated to have lost you. It is terrible just to write this note. Rest in peace, Dan xxx."
"To everyone else who reads this remember ?The dead don't die. They look on and help'."
