Members of a jury in the trial of a businessman accused of murdering a Manchester Metropolitan University lecturer and his family in their home wept as a harrowing 999 call was played in court.
Anxiang Du, 54, is accused of stabbing to death lecturer Jifeng "Jeff'" Ding, his wife, Ge "Helen" Chui, and their two daughters, Xing "Nancy" 18, and Alice, 12, on April 29, 2011.
Du has denied carrying out the four murders on the day of the royal wedding between Prince William and Kate Middleton.
Prosecutors allege Du stabbed the Ding family in order to "avenge himself" after their business relationship turned sour and he ended up owning thousands of pounds in costs following a lengthy legal battle.
Opening the murder case for the prosecution at Northampton Crown Court, William Harbage QC told the court that on the day of the Royal wedding, Anxiang Du "savagely stabbed to death" a family of four.
Mr Harbage said the prosecution case was that Du, on the day of the Royal wedding between Prince William and Kate Middleton, on April 29, 2011, travelled to Northampton from his home in Coventry, via Birmingham.
Not content with killing them, the mother and father, in the kitchen of their own home, he then went upstairs to find their two daughters, Nancy aged 18 and Alice aged 12, cowering in a bedroom.
He cold-bloodedly stabbed them to death as well.
– Prosecutor William Harbage QC
The prosecutor told the court that Du was "armed with a kitchen knife, and savagely stabbed to death firstly the two people, Mr and Mrs Ding, with whom he had been having a long-running legal dispute".
