A 36-year-old woman, who is believed to be the sister of his wife, was also found dead. 

It has since been revealed that a 999 call was made from the property at 6am but police were not sent to the address.

Here are seven questions that remain unanswered. 

Who was alive when the 999 call was made at 6am and what was said in the call?

It is understood that Mr Kuczynski made the call but there has been no confirmation of the reasons why he rang or what was said.

Why did police decide not to respond to the 999 call?

Norfolk Constabulary has not said why it did not send officers to the address following the call from Mr Kuczynski.

The incident has been referred to the Independent Office of Police Conduct (IOPC) which will assess the circumstances of the call and determine the appropriate level of investigation required.

Due to the investigation, Norfolk Constabulary will not release any further information about the call at this time. 

Giles Orpen-Smellie, the Police and Crime Commissioner for Norfolk, said: "I am clear that the residents of Norfolk must be able to depend on the effective working of the 999 system."

Why was another call made to police at 7am?

A member of the public was concerned for the family (Image: Facebook)Another 999 call was made by a member of the public at 7am who was concerned for the welfare of the family inside the Allan Bedford Crescent home.

Police arrived on that scene at around 7.15am and forced entry to the address.

It has not been confirmed who the member of the public was.

How did the children die?

The cause of death of the two children has not been confirmed. 

Post-mortem examinations were carried out on Mr Kuczynski and the 36-year-old woman on Sunday.

Mr Kuczynski died as a result of a single stab wound to the neck while the woman died from stab wounds to the neck. 

Post-mortem examinations on the two young girls will be carried out on Wednesday.

Where is the mum of the two girls?

Some neighbours have reported not seeing Mr Kuczynski's 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.

The mother of the children has not been named by police but Detective Chief Inspector Chris Burgess said specialist officers are supporting a family member in Norfolk. 

Why was her sister at the house?

The 36-year-old woman, who was not a permanent resident at the address, is believed to be the sister of Mr Kuczynski's wife. 

It is not clear why she was at the house that morning. 

Did Mr Kuczynski receive mental health support after he went missing?

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.

This handling of this incident has also led to a referral to the IOPC. 

It is unclear whether Mr Kuczynski or the family received any mental health treatment or other support following this incident.
