Two adults found dead with two children at a house in Norfolk died as a result of stab wounds to the neck, a postmortem examination has found.
The bodies of a 36-year-old woman, a 45-year-old man and two young girls, reportedly aged 12 and seven and believed to be daughters of the male, were found in a house on Allan Bedford Crescent, Costessey, on Friday. All four were related, police said. The man has been named locally as Bartłomiej Kuczyński, a structural engineer, and the 12-year-old daughter as Jasmin Kuczyński.
