"Kidnappers who abducted a mother and shot her dead before leaving her in a burnt-out car
had sent her husband countdown messages leading up to her execution.
'There are conflicting reports
as to how much was owed,
anywhere between seven kilograms (worth roughly $1.2million)
and 70 kilograms
(worth as much as $8million)'
police source said.
Investigators are working to find whether Ms Tran was shot in the head before the car was set on fire.
A bullet casing was discovered on the floor of the burnt-out vehicle,
but forensic pathologists have been unable to confirm if there were bullet wounds on Ms Tran's charred remains.
NSW Police Homicide Squad commander Detective Superintendent Joe Doueihi said
officers believed there was a 'conflict'
between Mr Nguyen
and 'upper echelons' of the organised crime network."
New details have emerged about the moments before the brutal murder of Thi Kim Tran.
