A BUSINESSMAN who stabbed a family of four to death has been found guilty of their murders.

Anxiang Du, 54, was convicted by a jury at Northampton Crown Court of murdering Manchester Metropolitan University lecturer Jifeng "Jeff" Ding, his wife, Ge "Helen" Chui, and their two daughters, Xing "Nancy" 18, and Alice, 12, on April 29, 2011.

Jurors rejected the claim that Du, from Coventry, should be convicted of manslaughter on the basis of either diminished responsibility or loss of control. He will be sentenced today.

During the trial, the jury heard how Du "massacred" his former business partners Mr and Mrs Ding in revenge after he lost a 10-year legal battle over a Chinese herbal medicine business. Losing the case left Du "angry, humiliated and facing financial ruin" as he owed some £88,000 in costs, jurors heard.
