Graphic showing number 10 Pioneer Drive, Northampton, where the Ding family were murdered by Anxiang Du. The bodies of Jeff and his wife Helen were found downstairs in the kitchen and their daughters were found in the corner of an upstairs bedroom. A man who killed a family of four with "ruthless efficiency" has been found guilty of murder by a jury at Northampton Crown Court. Anxiang Du, 54, showed no mercy as he stabbed the family a total of 51 times. The Chinese businessman wanted revenge after a lengthy legal battle with the Ding family left him with an £88,000 bill and facing financial ruin. University professor Jifeng 'Jeff' Ding, his wife Ge 'Helen' Chui and their daughters Xing, 18 and Alice, 12 were 'slaughtered' in their own home at Wootton in Northamptonshire on April 29 2011, the day of the royal wedding. Anxiang Du left a farewell note to his wife and travelled to the home with a kitchen knife. Mr and Mrs Ding died in their kitchen. The killer then went upstairs to find their two daughters cowering in a bedroom. The court heard that he showed them no mercy. As the family lay dead, Du stole their car and went looking for another former business associate, but he wasn't at home. The killer drove to London and took a bus to Paris before travelling to Spain. He then took a boat to Morocco.
