Anxiang Du 'Massacred Ding Family In Revenge' A Chinese businessman "massacred" a family of four in revenge for a lengthy legal battle which left him "faced with ruin," a court has heard. University professor Jifeng "Jeff" Ding, wife Ge "Helen" Chui, and daughters Zing, 18 and Alice, 12, were stabbed to death at their home in Wootton, Northants, on April 29, 2011, the day of the Royal Wedding. Northampton Crown Court heard that Anxiang Du, 54, took a kitchen knife to the Dings' house, stabbed the parents to death, then found their daughters "cowering in a bedroom" upstairs and "cold bloodedly stabbed them." A post-mortem examination found the four family members were knifed a total of 51 times. The prosecution said it was "quite simply revenge" after a business relationship between the Du family and Ding family "turned sour," and ended with Du owing £88,000 in costs, following a lengthy legal battle. Proceedings were relayed to Du with the help of an interpreter. At times, he appeared to be in tears as the prosecution opened the case. The jury was told that after Du killed the family, he stole their car, and went looking for another business associate in Northamptonshire, but he was not at home. He then went "on the run" and drove to London, took a coach to Paris, travelled to Spain, then took a boat to Morocco. He was tracked down at a building site and was extradited to the UK in February this year. The court heard that despite a 20-second 999 call to police from Alice's mobile phone, where "more than one female" could be heard screaming, the bodies were not discovered for two days, when neighbours became "suspicious" about the lack of activity at the house. Alice was found on the floor of a bedroom with her phone near her head. Her sister was on the bed in a "prayer position." All four had suffered wounds to their chests. The jury were told that on the day of the killings, Du was "a man on a mission." He travelled from his home in Coventry to his Chinese medicine shop in Birmingham and left a note which said "everyone has to say farewell some day." He was then filmed on CCTV getting a train to Northampton, then a bus to Wootton. The prosecution said there was "no dispute" Du was responsible for the killings, his fingerprints were found in blood at the scene. He has pleaded not guilty to four counts of murder and is expected to claim he should only be convicted of manslaughter on the grounds of diminished responsibility. The prosecution said it was a "clear case of murder."
