Two teenage boys, aged 14 and 16, have been charged with murder in Sydney for their alleged roles in a mistaken identity shooting that led to the death of Marco Tapia, a university student, on September 1. Police believe the teens facilitated the crime by providing vehicles and a weapon but were not present during the actual shooting. Detective superintendent Joe Doueihi described the incident as having "all the hallmarks of an organised crime murder" despite the involvement of young individuals who may have been lured into criminal activity for financial gain.

Story summary
Marco Tapia, a 23-year-old biomedical engineering student at the University of Technology Sydney, was shot dead in his Glen Alpine home on September 1. Police believe it was a case of mistaken identity during what they suspect was an organized crime-related attack. The incident occurred when three masked men stormed the house around 3:40 AM and fired shots at Tapia while he slept; Tapia had no criminal record, only a minor traffic offense.
Tapia's parents, Sergio and Claudia, described finding their son in his bedroom as "a horrific nightmare" that has forever changed their lives. His sister Cassie was devastated to learn she would be getting married without him later that year. The NSW government responded with a significant crackdown on organized crime, fearing it had lost control of Sydney's streets.
Two teenagers, aged 14 and 16 from Fairfield, were subsequently charged with murder related to this incident as part of Strike Force Gareno investigations. They face multiple charges including participating in criminal activities, possession of unauthorized firearms, and taking conveyances without consent. The teens have been refused bail pending a children's court appearance.
