Report due into police handling of murder case
by Lucy Kapasi
The Ding family were killed in Northampton last April on the day of the royal wedding.
Today's report by the Independents Police Complaints Commission is expected to address why the prime suspect, Anxiang Du, still hasn't been found.
University lecturer Jifeng Ding, his wife Helen and their two daughters were found stabbed to death in their home in Northampton on May 1.
The prime suspect is thought to have fled to London after their deaths on April 29 and there were a number of sightings of him although he has never been found.
