Neighbours heard explosions coming from the property, as smoke poured from the roof, which partially collapsed
‘I hear glass breaking so I went to the kitchen and check it,’ a witness said
‘Then I hear a woman’s voice saying ”help, help” and then I look at the bigger window and I saw the smoke on the roof.’
Police Inspector Daniel Bragg said: ‘It was a loud explosion, quite significant, and the neighbour that heard that explosion contacted the police.
‘I’m told that the fire could be seen from a fair distance away and it was the flames and the smoke that actually led people to the address.’
Inspector Bragg said one neighbour had told police that there was ‘some yelling’ beforehand.
‘Screams were heard for help, but exactly where those screams were coming from and who those screams were coming from is yet to be ascertained.’

Graeme’s brother told the Courier-Mail: ‘Graeme was there to make sure Dylan wasn’t going to do a runner, as he was to face court on a charge of abusing police.
‘Graeme was a good man and would do anything for his kids.’ He said Dylan’s sister ‘has lost her whole family in one morning.’
Tributes have poured in for the SES volunteer.
‘The Whitsunday SES family is shattered tonight we have lost a great mate,’ a Facebook post reads.
Police are investigating whether the fire was deliberately lit, Police Inspector Daniel Bragg told reporters at the scene on Tuesday
‘Screams were heard for help, but exactly where those screams were coming from and who those screams were coming from is yet to be ascertained,’ Inspector Bragg said. Authorities are pictured at the scene
‘So hard to believe that his smile, his mad humour, and endless positive energy is no longer with us.
‘He turned the Airlie Beach Group into a active, fully functional team that felt very much like a family. We are going to miss him on many levels. Rest in peace Graeme.’
It is not yet clear how the suspected murders and suicide were carried out.
Queensland Police declined to comment on the ongoing investigation when contacted by Daily Mail Australia on Wednesday night.
