An eighth person has been charged over the Logan bodies-in-the-box murders in Queensland after being extradited from New Zealand.
The 28-year-old man from Auckland has been charged with two counts of murder and will appear in the Brisbane Magistrates Court on Friday morning.
The victims, Cory Breton, 28, and Iuliana Triscaru, 31 were last seen alive on January 24 last year and their bodies were found in the locked metal box in a Kingston dam 18 days later by police.
Tuhirangi-Thomas Tahiata, one of seven men charged over the murders, confessed to hearing screams as the box was tossed in the water.
Both victims were allegedly lured to a unit before being beaten, tied up and locked inside the metal toolbox before Tahiata arrived, the Brisbane Supreme Court heard last year.
Tahiata allegedly admitted hearing kicking and screaming as he loaded the box with the victims inside into his truck and drove it to the dam.
The court heard he fired a warning shot into the air with his homemade gun before his co-accused Trent Michael Thrupp punched holes into the box with a claw hammer to help it sink.
The screams got louder as they pushed the box into the water and Thrupp yelled "time to die", Tahiata allegedly told officers.
They then went back to the dam days later and used rocks to sink the box after they found it floating on the surface, prosecutors allege.
Tepuna Tupuna Mariri, Webbstar Latu, Stou Daniels, Davy Malu Junior Taiao and Ngatokoona Mareiti are also charged with murder.
