Wales (Wales Times) September 18, 2026 – Four people arrested in Melbourne are being extradited to New South Wales after police alleged they were part of an interstate criminal group that used the same firearm linked to the mistaken‑identity killing of university student Marco Tapia in Sydney’s south‑west.

Who has been arrested and what are the allegations?

As reported by 1News on 18 September 2026, four people – a 22‑year‑old man from Epping, a 23‑year‑old man, a 26‑year‑old woman and a 16‑year‑old boy from Donnybrook – were arrested in Melbourne on Wednesday and appeared before Melbourne Magistrates’ Court on Thursday, where extradition to NSW was granted. Detective Acting Superintendent Brad Abdy told reporters the group travelled from Melbourne to Sydney on 30 August and is alleged to have carried out criminal contracts for two separate shootings in Hurstville and Turrella while in NSW, using the same firearm later found in the Glen Alpine family home where Tapia was killed.

Police allege the group has links to the notorious Alameddine crime family, though the four have not been arrested or charged in relation to Tapia’s murder. Officers will travel with the four to Albury Police Station, where they are expected to be charged over the alleged contract shootings.

What happened in the Tapia killing and related shootings?

Marco Tapia, 23, died in his bed during a break‑in shooting at his family home in Glen Alpine in Sydney’s south‑west in the early hours of 1 September. Detective Acting Superintendent Brad Abdy said a firearm found in the family home where Tapia was killed had been linked to the Victorian group.

According to 1News, the shooting in Hurstville unfolded about 2.30am on 31 August, when three unknown men forced entry into a home and a gun was fired into a wall; no one was home and the men left in a black sedan. About 30 minutes later, shots were fired into a grey sedan parked on the road in Turrella, a matter Abdy said was being investigated by the homicide squad, with evidence sharing underway to establish links.

How did police identify and track the group?

Detectives quickly identified four people who had allegedly travelled from uk/local/newport/victoria/">Victoria to carry out the criminal contracts, Abdy said. Search warrants were executed at short‑stay accommodation in Lurnea and Campbelltown on 9 September, with police believing the group had stayed at those locations between 30 August and 1 September.

“Criminals can’t come interstate, commit offences, run away and hide back in their states and think that they’re going to avoid detection and prosecution for their crimes,” Abdy said, adding it was equally important that people overseas tasking criminals in Australia could not use borders as protection from prosecution and identification.

Who else has been charged over Tapia’s death?

Separately, two boys aged 14 and 16 were arrested and charged on Wednesday over their alleged roles in Tapia’s murder and will remain behind bars until they next front a children’s court on 13 November. As reported by 1News on 17 September, Detective Superintendent Joe Doueihi said the teens were not present at the alleged murder but were part of a joint criminal enterprise through their actions, with police alleging they were involved in preparation and aftermath activities including disposing of vehicles, supplying weapons and cleaning the residence in exchange for financial payment.

Both teens were charged with murder, participating in a criminal group contributing to criminal activity, possessing an unauthorised prohibited firearm and two counts of taking a car without consent; the younger teen was also charged with damaging property by fire or explosion. Homicide commander Doueihi said three other people are suspected of committing the fatal home invasion, and those three remain at large.

What is the wider pattern of mistaken‑identity shootings in NSW?

Tapia’s death was Sydney’s first of two suspected mistaken‑identity shootings in as many days, followed by the killing of Joshua Macdonald, 40, at his home in Merrylands West on 2 September. As reported by The Guardian on 12 September 2026, an 18‑year‑old man was charged with murder over Macdonald’s death after police alleged he operated a drone likely conducting surveillance on someone or some premises as part of a botched gang hit.

There have been five suspected cases of mistaken identity since May 2025, with fears reckless overseas criminal leaders are worsening the potentially misguided attacks, according to 1News coverage in early September. On 702 ABC Sydney, Taskforce Falcon Commander Detective Superintendent Jason Box said eight people had been murdered in cases of mistaken identity since 2021, with arrests made in relation to six of the killings.

Background of the particular development

The arrest and extradition of the four Victorians marks a significant escalation in NSW Police efforts to disrupt interstate and overseas‑tasked criminal networks implicated in a string of botched hits that have killed non‑targeted individuals. Investigators have increasingly pointed to a shift in organised crime tactics, with younger, cheaper and less experienced operatives hired by gang leaders based overseas to carry out surveillance, logistics and shootings, a trend authorities say has contributed to fatal errors in target identification.

The alleged link to the Alameddine crime family underscores longstanding concerns about entrenched syndicates using cross‑border movements to execute contracts while attempting to evade detection by returning to their home states. The execution of search warrants at short‑stay accommodation in Lurnea and Campbelltown, combined with forensic linking of a single firearm across three incidents, illustrates the multi‑agency, evidence‑sharing approach now central to Taskforce Falcon’s operations against organised crime.

Prediction: how this development can affect the audience

For residents in Sydney’s south‑west and broader NSW communities already anxious about random violence, the arrest of an interstate group allegedly tied to multiple shootings may offer some reassurance that police are actively pursuing networks beyond immediate suspects. However, the fact that three suspected offenders in Tapia’s killing remain at large, alongside ongoing investigations into other mistaken‑identity cases, suggests the risk of further incidents has not been eliminated.

For young people and families, the charging of teenagers in roles supporting a murder – from supplying weapons to post‑crime clean‑up – could intensify debates about youth involvement in organised crime and the influence of overseas‑based recruiters. Law‑enforcement agencies are likely to increase visible patrols, surveillance operations and community engagement in suburbs linked to recent shootings, while prosecutors may pursue tougher penalties for those facilitating contract killings, even if they did not fire the weapon.
