How horror Sydney house fire started

The cause of the horrific house fire that killed three children in Lalor Park, Sydney, has been revealed as police wait to question a man in an induced coma.

Heartbreaking social media posts showing what appears to be a loving family have emerged after a devastating weekend house fire that killed three kids.

The horror inferno in Sydney’s Lalor Park was allegedly started after a man threw a flaming pillow at his partner.

Police allege the pillow was thrown at around 12.55am on Sunday and was followed by a second explosion that engulfed the property in flames.

It is not thought the pillow fire was solely responsible for the blaze and experts are working to determine what caused the second explosion, The Daily Telegraph reported.

Detectives are reportedly investigating whether an accelerant was used.

Today images emerged of the children celebrating the birthday of one of the siblings as their grieving mother lies in a hospital bed.

It’s hoped she will be released after spending days in an induced coma.

“We are so so so proud of you and everything that you have achieved,” the child’s mother wrote on social media post celebrating her son’s birthday, as reported by the Daily Telegraph.

“Mum, dad your sister and brothers love you so much and think your the best brother/son we could ever ask for.”

In another image she wrote, “Family, a bond like no other”.

The children’s father, who is believed to be responsible for the fire, is currently in a medically induced coma in hospital with police waiting to question him.

Police are puzzled as to what may have caused his alleged actions as there was no history of mental illness or domestic violence.

The only red flag was a phone call from neighbours to police in recent weeks after the couple could be heard arguing. But the dispute was quickly resolved.

Two boys, aged two and six, were taken to Westmead Hospital in a critical condition but died from their injuries.

Firefighters tragically found the body of a five-month-old girl inside the property after the fire had been extinguished.

The man’s de facto partner and four other children managed to escape after hero neighbour Jarrod Hawkins broke down the door to the property.

The fire is believed to have started at 12.55am on Sunday after a man allegedly threw a flaming pillow at his partner.

“The front door was locked, but I kept shoulder-barging it until I smashed it in,” Mr Hawkins told the Sydney Morning Herald.

“There was too much smoke, I couldn’t see a thing.”

Now, he has started up a GoFundMe to help the family “get back on their feet” after the tragedy.

“We are looking for donations for a very young family that survived a house fire and lost everything they had,” Hawkins wrote on the page.

“Although they have lost everything we are trying to help them get back on their feet with cloths (sic), housing and general costs.

“We are grateful for any and all donations. We thank you for your time and donations.”

Police claim a 28-year-old man allegedly tried to stop neighbours and officers from entering the burning home while a woman – who is the man’s partner – and seven children, aged between 10 months and 11 years old, were inside the property.

According to an update on Monday afternoon, the man is so wounded from the fire, it is uncertain if he will survive.

“At this stage it does appear the 28-year-old is responsible for multiple deaths of young lives that have been tragically taken away,” Homicide Squad Detective Superintendent Danny Doherty said on Sunday.

“We’re alleging the 28-year-old man took actions to prevent the young people inside being rescued.”

Police said the man allegedly yelled “let me die here” as he tried to prevent the rescue efforts.

The man’s partner is in hospital being treated for smoke inhalation.

The incident is being investigated as a domestic violence, multiple homicide incident.

There was no apprehended violence order in place against the man, police say.

The couple involved had been in a relationship for nearly a decade and are listed as being “engaged” on Facebook.

Detective Superintendent Doherty said the suspect was “not adversely known” to police, nor is he before the court for any other matters.

“These types of matters are just devastating. These are tragic circumstances,” he said.

“These are really extraordinary circumstances. We hope the community comes together, galvanises and helps the family.

“There’s more good than bad in the world. Tragedy usually brings out the best in people.”

NSW Premier Chris Minns described the incident as “horrifying and senseless”.

“These children deserved love and protection and a caring home,” he said.

“Our love and thoughts are with the surviving family members. NSW will support them for as long as necessary, as they seek to recover from this unfathomable event.

“Our thoughts are also with the emergency service workers who fought to save lives last night and who will also be recovering in their own way after a horrible night.”
