Detectives investigating the deaths of a man, his two daughters and a woman are not looking for anyone else in connection with the tragedy.
The bodies of engineer Bartlomiaj Kuczynski, 45, Jasmin Kuczynska, 12, and her seven-year-old sister, and a 36-year-old woman, were discovered at the property in Allan Bedford Crescent at the Queen's Hill estate in Costessey, near Norwich, at around 7.15am on Friday.
Police had received a call shortly before 7am from a member of public who raised concerns for the welfare of people inside. Officers arrived at around 7.15am and forced entry to the address and found the bodies.

Since then, detectives from the Norfolk and Suffolk Major Investigation Team have been working to establish the circumstances surrounding the deaths.
Detective Chief Inspector Chris Burgess, who is leading the investigation, said late on Saturday night: “We’ve spoken to witnesses and neighbours, carried out house-to-house enquiries, examined local CCTV and completed initial scene investigations. As a result of this, we’re not looking for anyone else in connection with the incident.
“Post-mortem examinations will be carried out for the man and woman on Sunday January 21 and on Wednesday January 24 for the two girls.
"While I can confirm all four people were found with injuries, we will not be disclosing any further information until these examinations have taken place and the cause of death has been established.

“This is a tragic incident, distressing for all involved and it is clear from the reaction it’s caused a lot of shock and upset in the local community. We’ve had uniformed officers patrolling the area today and these will continue tomorrow.”
Police confirmed Mr Kuczynski and his daughters lived at the address while the woman, although related, was visiting and not a permanent resident at the address.
The next of kin continues to be supported by specialist officers. A police cordon also remains in place at the scene.
The incident was initially referred to the Independent Office of Police Conduct (IOPC) on Friday due to police contact at the address on December 14, relating to a missing person enquiry.
Earlier on Saturday, the constabulary made a second referral to the IOPC concerning a 999 call made at 6am yesterday by the man at the address, prior to the incident, which did not result in the deployment of officers.
This newspaper understands that the call was made by Mr Kuczynski.
A Norfolk Police spokesman said: "The IOPC will assess the circumstances of the call and determine the appropriate level of investigation required. As a result, no further information relating to the circumstances of this call will be released at this time."
