The Russell Murders

On 9 July 1996, three bodies were found in a little leafy copse beside a country lane in Chillenden, Kent. Dr Lin Russell, 45, and her two daughters, Megan, six and Josie, nine, had all suffered brutal head injuries caused by a blunt instrument. They had been tied up and their family dog, Lucy, was also found dead nearby.
