[EX Q]: Dr Sabah Usmani and her five children, Maheen, Rayyan, Muneeb, Hira and Sohaib Shakoor died in the blaze in Barn Mead, Harlow in Essex on 15 October 2012.
Det Supt Rob Vinson told Chelmsford Coroner's Court all the evidence pointed towards murder but firefighters could not rule out an accidental cause.
Coroner Caroline Beasley-Murray recorded an open verdict.
Dr Usmani's husband, Dr Abdul Shakoor, was the only survivor of the fire, which may have reached temperatures of 800C (1,472 F), experts said.
All members of the family, originally from Pakistan, died from their injuries and inhalation of fumes, a post-mortem examination found.
Dr Usmani, 44, had wrapped herself around her three-year-old daughter, Maheen, in an attempt to save her, the court heard.
Her sons Muneeb, nine, Rayyan, six, and daughter Hira, 12, died soon after the blaze.
A third son Sohaib, 11, and Maheen were taken to hospital. He died later that morning while she lived for three more days.
Retired fire investigation officer, David Hajicostas, said Dr Usmani was found crouched over Maheen, an act which gave the girl three further days of life and a chance of survival.
"She was gathered over her on all fours, with a blanket over her," he said.
He told the court an accidental cause could not be ruled out but was "minded to think" it was deliberate.
Det Supt Vinson told the hearing the front door of the house was open, a laptop was missing and there had been a series of burglaries in the area that night.
He said no-one had been charged but it remained an "active investigation".
Ms Beasley-Murray said: "In order to record a conclusion of unlawful killing, I would have to be sure that somebody killed another without legal justification and intended to kill or cause serious injury.
"Sadly, there is also insufficient evidence to say it was an accident.
"Not all of the pieces of the jigsaw are there yet."

The officer is in a stable condition in hospital after the attack by a dissident republican group known as the 'new IRA'.
During Prime Minister's Questions on Wednesday, the Labour leader passed on the sympathies of "the whole House" for the "police officer who lost his life".
North Belfast MP Nigel Dodds later described Mr Corbyn's gaffe as "one of the worst displays of crass ignorance that could be imagined".
It is understood Mr Corbyn has written a letter to the Chief Constable of the Police Service of Northern Ireland to apologise for his error.
A spokesman for the Labour leader said: "He meant to say 'nearly died'", adding that Mr Corbyn "had not intended to cause offence".

[EX Q]: The Jewish Agency, which acts as a link for Jews around the world, said the exodus resulted from a rise in anti-Semitic attacks in Europe.
It reported that 9,880 western European Jews emigrated to Israel last year.
Around 8,000 came from France, where Jews have been targeted in a series of recent attacks, it said.
The agency also reported that about 800 Jews left Britain to Israel in 2015, the AP news agency reported.
Jews have been targeted in many European countries, such as Belgium and Denmark, but the worst attacks have been reported in France
The country's 500,000 Jewish population is the world's third largest, after Israel and the United States.
"That a record number of European Jews feel that Europe is no longer their home should alarm European leaders and serve as a wake-up call for all who are concerned about the future of Europe,'' Jewish Agency Chairman Natan Sharansky said, according to AP.

French Jews question their future
This week, a teacher in Marseille was stabbed by a boy who reportedly said he had done it for the so-called Islamic State (IS) group, the third attack on Jews in recent months in the city.
The attack prompted a local Jewish leader to ask men to stop wearing the traditional skullcap. France's chief rabbi, however, urged Jews to keep covering their heads.
In January 2015, four Jewish shoppers were killed by an IS supporter at a kosher supermarket, shortly after the deadly assault on the office of Charlie Hebdo magazine.
Since then, more than 700 synagogues, Jewish schools and community centres have been protected by police or soldiers.
