Tragic Shooting on September 1
On September 1, at about 3.40 a.m., 23-year-old Marco Tapia was shot dead while lying in bed at his family home on Mount Sugarloaf Drive in Glen Alpine, Sydney. Police say the home invasion was a botched organised-crime hit that mistakenly targeted Tapia, who had no known criminal connections.
Investigation and Charges
New South Wales Police allege that three males – two men aged 22 and 23 and a 16-year-old boy – entered the residence, one allegedly armed with a pistol, and confronted Tapia before he was fatally shot. The trio, identified as Vaifaalie Tuafuti, Omar Mohamed, and an unnamed 16-year-old, were extradited from Victoria on September 18 and charged with murder, two counts of special aggravated break-and-enter, and possession of an unauthorised prohibited firearm. They are due to appear in court on the Wednesday following their extradition.
Detective Superintendent Joe Doueihi said the two teenage boys previously arrested – aged 14 and 16 – were not part of the invasion crew but were involved in “preparation, planning, and aftermath,” including supplying weapons, disposing of a “kill car,” and cleaning a residence used by the attackers. Their parents were described as “shocked” and “devastated.”
A 26-year-old woman, Amenah Abusud, was also extradited but faces separate charges for criminal-group and accessory offences. Police link the trio to the Alameddine crime family and a broader gangland conflict with the so-called Coconut Cartel.
Background: Organized-Crime Context
Investigators believe the attack was part of a violent gangland war, with the perpetrators possibly recruited by overseas crime leaders—a practice described as increasingly common. Ballistic analysis matched cartridge cases from the Glen Alpine scene to other recent shootings linked to the same criminal network.
