A father who was found dead with his two young daughters and another woman at the family house had gone missing before Christmas prompting a police search.
Police discovered four people dead after forcing their way into the property in Allan Bedford Crescent in Queen’s Hill, Costessey, on Friday morning following a call from a concerned member of the public.
The bodies of Bartlomiaj Kuczynski, 45, a structural engineer who lived at the property, and girls aged 12 and seven believed to be his children were found inside, all with injuries, in what police said was an "isolated incident".
Police said the 36-year-old woman found dead “was visiting and didn’t live at the property”.
Some neighbours have reported not seeing Mr Kuczynski's Thai-born wife Nanthaka for months and said her sister recently moved into the family home.
But this newspaper understands Nanthaka had been living at the home and her sister had not moved in.

Forensic teams were continuing investigations at a house on Saturday as part of an investigation into the circumstances surrounding the deaths.
Detective Chief Inspector Chris Burgess said: “We do believe they were all family members at this time.
“Three of the people are believed to reside at the address and another one not permanently.”
He confirmed that officers had been called to the same house on 14 December as part of a missing persons inquiry.
That incident will be re-examined as part of the investigation, he added.
Neighbours said Mr Kuczynski himself had been reported missing and that police had used a drone to search the area with the father later found safe.
A police cordon remains in place in Allan Bedford Crescent with access into Stony Grove and Foxhouse Road also restricted.

Neighbours whose houses are inside the cordon or who have limited access are being required to sign and in and out to access their properties.
One neighbour walking his dogs, who preferred not to be named, said: “Everyone is just really saddened about what has happened. No-one can believe it.
“You don’t expect to be with a police cordon but they are just doing their job. It’s nothing compared with what the relatives are experiencing right now. Our thoughts just go out to them.”
Next of kin have been informed and specialist family officers are supporting them, said DCI Burgess.
No cause of death has been given and post-mortem examinations are due to be held.
Churches in the area are opening so people can pay tribute.
The Bishop of Norwich Graham Usher said local clergy were offering support in the communities they serve and would be opening churches over the weekend for those who wish to pay tribute.
The Rev Laura Montgomery, rector of the Easton Benefice and the vicar of Queen's Hills, lives and ministers on the estate.
She said: "I live here on the Queen's Hills estate and we are all shocked by this terrible tragedy.
"My prayers are with all impacted by these events. We are a close knit community and the grief and shock will be with us all for a long time.
"As the local vicar I am here to support the local community. I will be out and about on the estate in the coming days if anyone needs to talk. The parish Church in Easton remains open with a space for anyone who wishes to light a candle, reflect and pray."
The Diocese of Norwich Facebook account wrote: “Our thoughts and prayers are with all those impacted by the tragic news in Costessey.”
