Joshua Macdonald, 40, was shot dead at a Merrylands West home on 2 September in what police believe was a case of mistaken identity. He had no known links to organised crime and was not known to police.
Police arrested the teenager while he was operating a drone, which they say he was likely using to conduct surveillance on a person or premises. A forensic examination of the drone “allegedly uncovered evidence to suggest involvement” in the fatal shooting, according to police.
The teen has been accused of using the drone to pass intelligence to the shooters, who allegedly targeted the wrong person. He has been charged with murder.
Authorities have not released the name of the accused, who is due to appear in court at a later date.
