The two sisters found dead alongside their dad and aunt had been stabbed in the neck, police have revealed.
Schoolgirls Jasmin, 12, and Natasha, 8, were found with dad Bartlomiej Kuczynski, 45, and their aunt Kanticha Sukpengpanao, 36, at a property in Costessey, Norwich on Friday.
Norfolk Police have now confirmed that all four family members died of stab wounds to the neck. The deaths of Jasmin, Natasha and Kanticha are being treated as murder but police said Bartlomiej’s death is not being treated as suspicious and no one else is wanted in connection.
There has been speculation surrounding the tragedy since four bodies were discovered by police at a house in Allan Bedford Crescent at around 7.15am on Friday morning after a 999 call from a member of the public.
A man had earlier called 999 from the property at around 6am that day, but police were not dispatched. Detectives said the man and two children lived at the address, but the woman was visiting and lived elsewhere.
Outside the family’s house, flowers and toys have been left in memory of the girls, just outside the police cordon. One tribute read: “Jasmine, you were such a sweet, caring girl, yourself and your sister didn’t deserve to have your lives taken away. You would always be smiling in primary school. Fly high beautiful girls.”
Detective Chief Inspector Chris Burgess is leading the investigation. He said: “We understand how incredibly shocking this incident is for all involved and for the wider community and that this latest update adds to the sense of heartbreak.
“Our thoughts are with the family of those found at the property grieving such a traumatic loss.
“We would like to thank the community for their help and will continue to provide reassurance patrols in the area.
“A cordon will remain on at the address whilst we finalise our detailed examination of the scene.”
The incident has been referred to the Independent Office of Police Conduct after the first 999 call did not see officers deployed.
There was also police contact at the address on December 14, relating to a missing person inquiry.
IOPC regional director Charmaine Arbouin said on Tuesday: “Norfolk Constabulary established that the man had made a 999 call to the force shortly before 6am on January 19.
“During that call the man expressed concerns for his own mental state saying he was confused. He was advised to seek medical advice and police did not attend. At around 7am the force received a call from a dog walker concerned for the welfare of those within the home.
“Officers attended shortly after and, tragically, found the man, a woman and two children dead. Following a mandatory referral from the force we have decided to investigate and will be examining if the force’s handling of the contact they had with the man was appropriate and in line with force policy, training and procedures.”
