A TRAGIC new detail has emerged following the deaths of a dad, his two daughters and sister-in-law in a suspected murder-suicide.
Jasmin Kuczynska, 12, and eight-year-old Natasha Kuczynska were discovered at the home in Costessey, Norwich, on January 19.
Dad Bartlomiej Kuczynski, 45, and the children's aunt Kanticha Sukpengpanao, 36, were also found after a 999 call.
An inquest into the quadruple tragedy heard today how Natasha and Jasmin's bodies were identified by a neighbour in hospital.
Norfolk area coroner Samantha Goward appeared to cry as the heartbreaking details were revealed.
The hearing was told Natasha's provisional medical cause of death was recorded as "sharp force injuries of the neck".

Kanticha, who was visiting from Thailand, died from "stab wounds to the neck", the court was told.
The coroner adjourned the hearing ahead of a pre-inquest review on April 29.
She also ordered a report from the mental health trust after it emerged Bartlomiej underwent an assessment before the tragedy.

Norfolk Police confirmed the deaths of Jasmin, Natasha and their maternal aunt are being treated as murder.
The dad's death is not being treated as suspicious and officers are not looking for anyone else in connection with the killings.
The Independent Office for Police Conduct (IOPC) has launched a probe into the quadruple tragedy over previous contact with Bartlomiej.
A missing person enquiry was made on December 14 after he vanished from the property.
He was later discovered close to his home and was taken to the Norfolk and Norwich University Hospital to undergo a mental health assessment.
But it has now emerged the dad left before any tests could be taken, with the hospital confirming it does not provide mental health services.
Norfolk Police force also referred itself to the watchdog over a 999 call Bartlomiej made before the horror.
Police did not send any officers to the home and instead showed up an hour later when a dog walker raised concerns.
The watchdog said of Bartlomiej's call: "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."
How mystery still remains over quadruple tragedy
QUESTIONS have been mounting over how the four deaths happened after it was revealed dad Bartlomiej called 999.
Despite warning officers over his mental state, he was told to seek medical advice.
Here are some unanswered questions that remain over the tragedy.
Why did cops fail to respond to the call?
Norfolk Police have still not confirmed why they didn't send officers to the home when Bartlomiej expressed concerns.
He told 999 he had "concerns" for his mental state and was "confused".
The IOPC is now investigating why that call was ignored.
What is the 'missing person' enquiry?
In a second IOPC referral, it was revealed police had prior contact with the family before the tragedy.
Officers confirmed this was in connection to a missing person's enquiry in December 14.
It was reported Bartlomiej had gone missing but was later found wandering in woodland.
Why did cops only respond to the second call?
The alarm was raised an hour after the first 999 call when a dog walker raised concerns for the welfare of people inside.
It is not yet clear why that phonecall was responded to but the dad's was ignored.
