Woman, 36, and man, 45, found dead alongside two young girls at home in Norwich had ‘stab wounds to the neck’, police reveal

A 36-year-old woman and a 45-year-old man found dead alongside two young girls at inside a home in Norwich on Friday both died from stab wounds to the neck, police have said.

The bodies of Bartlomiej Kuczynski and his two children were found by police at the home in Costessey on Friday morning, alongside the body of a woman who has not been identified.

The woman died as a result of multiple stab wounds to the neck while the man, who was named locally as the father-of-two, suffered a single stab wound, police said. 

Post-mortem examinations on the two girls, identified as Jasmin Kuczynska, 12, and her seven-year-old sister, will be carried out on Wednesday.

It comes after it was revealed police officers ignored a 999 call from the address one hour before the bodies were discovered. Police are continuing to probe the deaths and confirmed they are ‘not looking for anyone else’.

Police at the scene in Costessey, Norfolk, on Friday after four bodies were found at a property 

Norfolk Police earlier confirmed they had received a call from a man at the address at 6am but officers did not attend.

Police were only sent to the house after receiving a second call at 7am from a member of the public, who was concerned about the people inside. The four injured bodies were discovered when police broke in at 7.15am.

As a result, Norfolk Police confirmed that it had referred itself to the Independent Office of Police Conduct (IOPC).

The force said a separate IOPC referral had already been made over their involvement with the family on December 14, when Mr Kuczynski was reported to have gone missing and was later found wandering nearby. 

The married father worked as an engineer in the property trade and had lived in England for the past 20 years. He graduated from Wroclaw University of Technology in Poland.

Officers said the 36-year-old woman found dead ‘was visiting and didn’t live at the property’.

Mr Kuczynski’s Thai-born wife Nanthaka had reportedly not been seen by neighbours for months and it is understood her sister recently moved into the family home to help look after them.

Detectives from the Norfolk and Suffolk Major Investigation Team have ruled out any third-party involvement in the deaths.

Detective Chief Inspector Chris Burgess, who is leading the investigation, said this evening: ‘Following this latest development we remain satisfied no one else was involved in this incident.

Jasmin Kuczynski, 12, and her sister, seven, were described as ‘beautiful girls’ by neighbours

‘This latest information will only add to the distress and shock felt by members of the local community and it’s why, from the outset, we’ve been determined to carry out detailed and methodical enquiries to make sure we fully understand how this incident has happened.

‘I would like to thank the community for their support and for the many people who have called offering information. We continue to work through this and will get back to everyone who has been in touch.’

He added that a police cordon remains in place at the scene and there will be a continued police presence in the residential area tomorrow.
