Abbey Forrest, 19, her partner known as Indi, and their 19 day old baby daughter have been identified as the family who died in a fire inside their Point Cook townhouse on Wednesday morning.
The townhouse was destroyed by the fire, and two neighbouring properties were also damaged.
Police have charged a 46-year-old woman with murder and arson causing death, after arresting her in Airport West on Thursday morning.
Emily Forrest, Abbey's sister, said the couple were new parents who moved into the townhouse less than three weeks ago. Rest In Peace. #murder #arson #familydeath #murdered #restinpeace #justice
