An 18-year-old man has been charged with murder over the fatal shooting of 40-year-old Sydney tradesman Joshua Macdonald, in a major development in a suspected mistaken-identity underworld attack in Sydney's west. The teenager was arrested by Raptor Squad detectives in West Hoxton early Friday morning and is alleged to have carried out drone surveillance connected to the shooting. Police say a drone seized during the operation was forensically examined and allegedly contained evidence linking the teenager to the fatal attack.

Macdonald was shot dead in Merrylands West on September 2, after gunmen allegedly opened fire outside a home in broad daylight. Police believe he may have been an unintended victim and that the people responsible were allegedly looking for another person connected to organised crime. Authorities have said Macdonald himself had no known links to organised crime.

The latest arrest has added a new dimension to the investigation because of the alleged use of a drone before the shooting. Investigators believe the device may have been used to conduct surveillance and gather information before the attack. Police seized the drone during the West Hoxton operation and subsequently examined it for evidence.

The 18-year-old has been charged with murder and participating in a criminal group to contribute to criminal activity. He was refused police bail and is expected to appear before a bail court on Saturday. Because the matter is now before the courts, the allegations against him have not been proven. He is legally presumed innocent unless the charges are established through the judicial process.

A second man, aged 19, was also arrested during the same police operation. He has been charged with participating in a criminal group to contribute to criminal activity and driving a motor vehicle while his licence was suspended. Unlike the 18-year-old, the 19-year-old was granted conditional bail after appearing before Liverpool Local Court and is expected to return to court on September 24.

The investigation comes amid growing concern about organised crime and a series of suspected mistaken-identity shootings across Sydney. Police believe the killing of Macdonald may be connected to a broader conflict involving criminal networks operating in Western Sydney. His death has renewed attention on the recruitment of young people to carry out alleged criminal activities.

Authorities are continuing to investigate the circumstances surrounding the shooting, including the alleged role of the drone and the people who may have organised or facilitated the attack. Detectives are expected to examine digital evidence, surveillance material and other information gathered during the investigation.

The case is particularly significant because it demonstrates how investigators are using technology and forensic examination to identify people allegedly involved in organised criminal activity. Further court proceedings are expected to provide additional information as the investigation continues.
