A businessman has been convicted of murdering a family of four in a revenge attack after he lost a legal case against them.
Jifeng "Jeff" Ding, his wife, Ge "Helen" Chui, and daughters Xing, 18, and Alice, 12, were stabbed to death in Wootton, Northampton, in April 2011.
Anxiang Du had denied four counts of murder but admitted killing the family.
Helen's father Zuyao Chui told a news briefing outside Northampton Crown Court that he had listened to the trial with "deep sorrow and pain".
