Melbourne woman set to be extradited after gun allegedly linked to Sydney killing

Police are seeking to extradite a woman from Melbourne after detectives allege they have linked a gun from two Sydney shootings to the mistaken identity gangland murder of Marco Tapia.

Mr Tapia, 23, died after masked gunmen stormed his Glen Alpine home and shot him dead on September 1.

The university student was the sixth mistaken identity murder linked to Sydney's underworld war in the space of 18 months.

In documents obtained by the ABC from a Victorian court, NSW Police will allege a group of Melbourne men were involved in two shootings linked to the ongoing feud between the Alameddine crime family and the self-proclaimed "Coconut Cartel".

"The history of that conflict is characterised by retaliatory violence, firearm offences and acts of intimidation," police allege in a document submitted to a Magistrates Court this week.

The Coconut Cartel, which takes its name from a historic slur against Pasifika people, and the Alameddines are playing out a violent underworld war on Sydney's streets while their leaders remain offshore.

Police have stated that Mr Tapia was not involved in organised crime and that detectives believe his death was tragically an error by his killers.

Two teenagers on Thursday were charged over their alleged roles in the murder of Mr Tapia.

The Melbourne woman, 26-year-old Amenah Abusud, is alleged to have been "recruited by an organised crime network, was tasked, and received payments to participate" in two shootings prior to Mr Tapia's death.

The ABC understands the NSW Police Raptor Squad are also attempting to extradite three other Melbourne men over their alleged involvement in the two shootings.

Police, in the court documents, allege the weapon used in the two shootings was also used to kill Mr Tapia.

According to the court documents the woman and several men set off from Donnybrook, in Melbourne's north, in a Hyundai two days before the shooting of Mr Tapia.

Police allege Ms Abusud "utilises" the same Hyundai.

Court documents state police tracked the vehicle at Campbelltown before CCTV captured the group of men at a local AirBnB.

A day before Mr Tapia's shooting, documents allege, the group broke into and shot up a home in Hurstville before its owner received a threatening message from an international number on WhatsApp.

Hours later the document states the same group shot up parked cars at a home in Turrella.

Police said in their statement of alleged facts that blood from one of the shootings identified one of the Melbourne men and gun cartridges were matched to a third shooting: the death of Mr Tapia a day later at Glen Alpine.

Investigators from the NSW Police's Raptor Squad are seeking to have Ms Abusud extradited from Victoria today, alleging she "is at risk of attempting to flee the country".

Police are seeking the woman's transfer interstate over charges related to the shootings at Turrella and Hurstville, but not in relation to the shooting of Mr Tapia.
