Tran had no knowledge of her husband’s alleged criminal activities,Doueihi said. He said Tran’s husband,who was interstate at the time of her death,had allegedly been working for the organised crime network when the 45-year-old was killed. He has not been charged over his alleged involvement with the criminal group.

Doueihi said the organised crime network was believed to be involved in large-scale methamphetamine manufacturing and was made up of predominantly Vietnamese males,but he added there was no information or evidence suggesting the leaders of the group were linked to South-East Asia organised crime groups.

Detectives executed a search warrant at a vacant rural property in Springdallah,west of Melbourne,that had been used as a drug lab. No one was at the property at the time of the raid and no arrests have been made.

The eight-year-old boy remains in an induced coma. He was expected to come out of the coma on Tuesday,but could suffer life-long implications from his injuries. The 15-year-old boy was not physically hurt,but suffered psychological injuries from the ordeal,Doueihi said.

On Monday,Tran’s loved ones shared their shock at the 45-year-old’s death.

A close friend,who chose to remain anonymous for privacy reasons,said Tran migrated from Vietnam about a decade ago,and she became friends with her through Sydney’s Vietnamese community a few years later.

The woman said that even when Tran struggled with the death of a family member about a year ago,she was “always happy to see her friends and share meals”.

“This is so awful … She didn’t deserve this … Everyone is in shock,” the friend said.
