Marco Tapia, 23, was shot dead in his bed after assailants broke into a house in Glen Alpine in the early hours of September 1. Police have confirmed the wrong address was targeted in what they describe as a mistaken identity killing linked to organised crime.
Detectives arrested a 22-year-old man, a 23-year-old man, and another 16-year-old boy in the town of Junee, about 400 kilometres south-west of Sydney, on Tuesday morning. NSW Police allege the three entered the home and one of them fatally shot Tapia with a pistol.
Two boys, aged 14 and 16, were previously charged and remain before the courts for allegedly staging vehicles and providing the weapon used in the attack.
Police said in a statement: "Detectives will allege in court the three males – one allegedly armed with a pistol – entered the home and confronted Mr Tapia, before he was fatally shot." The three new suspects are expected to face court on murder and related charges.
