A teenage mother who was the sixth person to be charged over the death of a 16-year-old boy sipped on a takeaway coffee and casually told reporters she had ‘no idea what happened’ days before allegedly handing herself in.

Kayla Dawson was arrested at an address in Doonside in Sydney’s west about 3pm on Sunday and formally charged with murder.

The teenager is accused of luring the victim to her home on Perigee Close in Doonside, where he was allegedly set upon by four boys aged between 13 and 15, along with a 15-year-old girl.

Daily Mail Australia understands the boy was told there would be a ‘huge party’ at the address, and that he trusted Dawson. 

Disturbing video of the brutal 48-hour beating was distributed on social media apps and was recommended to the victim’s friends in their’ ‘for you pages’ for days following the incident.

In the shocking footage, he was forced to repeat the phrase ‘f**k the ’21,’ an apparent reference to postcode wars in the community. 

’21 District’ is a group of gangs also known as the ‘Innerwest Brotherhood’ linked to several postcodes, including Guildford, Merrylands and Blacktown.     

The boy was also seemingly made to apologise to the ’27’ postcode, comprising the suburbs of Mt Druitt and Doonside. 

Police are investigating whether the boy’s death was linked to increasing postcode violence in the community.  

Sporting a Lonsdale jumper and black cap, Dawson agreed to be interviewed by 7News at the scene the day after the boy was found and rushed to hospital.

‘I can’t go back to my house because it’s still under investigation,’ she said as she sipped on her coffee and rolled her eyes. 

‘It was like a bashing… I don’t know what it’s over.’ 

The 16-year-old victim endured two days trapped inside the home with at least six offenders, though in social media posts Dawson denied ever laying a finger on the boy

The 16-year-old victim endured two days trapped inside the home with at least six alleged offenders, though in social media posts Dawson denied ever laying a finger on him.

‘It was not me that killed him… I didn’t set him up to die,’ a message from Dawson’s Facebook account reads. 

She later allegedly told former friends she would ‘hand herself in to police’ when they called to question her about the boy’s death.

In audio heard by Daily Mail Australia, Dawson was concerned about ‘losing everyone’ over the alleged incident. 

Dawson is due to appear in Blacktown court on Monday charged with murder, take or detain in company with intent, actual bodily harm, and cause grievous bodily harm to person with intent. 

The victim was allegedly targeted after a fake pair of Airpods went missing last month.

Sydney rapper Big Kash slammed the toxic culture which promoted and glorified violence within young fans.

‘This is the life that all you dumb rappers glorify to these little kids without telling them the consequences of this life… condolences to the family, nothing but pain and misery on that side of the fence,’ he said in a tribute post. 

About 5.40pm on Wednesday, August 4, emergency services were called to the Doonside home where they found the victim unresponsive with injuries to his head and chest.

He was rushed to Westmead Hospital where he spent three days in a coma before dying on Saturday, August 7.

Outrage in the local community is palpable, with more than 13,000 residents demanding the teenagers involved be ‘locked away for life’.

Others are questioning why their families allowed them to stay out for two nights, particularly during Sydney’s Covid lockdown.

Criminal psychologist explains why street violence is on the rise 

Tim Watson-Munro, a criminal psychologist, said young people have always sought a sense of belonging and community within their peer group.

But he explained this becomes dangerous when young people find ‘security in numbers’ within dysfunctional groups.

‘This leads to trouble,’ he told The Daily Telegraph.  

A former New South Wales detective said increased violence in lower socioeconomic communities was often due to a sense of hopelessness. 

‘A high proportion of public housing, a high proportion of migrants and a high proportion of unemployment, in any city in the world that is a recipe for disaster,’ Western Sydney University Dr Mike Kennedy said. 

‘The governments leave it to the police to deal with so they don’t have to accept responsibility.’
