Torney admitted to hiding the body in the roof but denied any part in her death.
After three days of deliberation, the Supreme Court jury found Torney not guilty. He was also acquitted of a second manslaughter charge.
Following the trial, new information has come to light about Torney’s drug use and violent past.
The Herald Sun reports that Torney attacked a police officer 13 years ago with a hammer in Queensland after being approached over driving offences. He was sentenced to eight months in jail, but it was suspended.
Tonrey was also reportedly being treated for aggression and anger management, according to the publication.
The Herald Sun also reports Torney was coming down from a five-day speed binge on the day of the murder and was heard threatening the child the previous day.
Neighbour Jermayne Kennedy told detectives he saw Mr Torney standing over the sobbing child and saying: “Shut the f--- up, you little c---.”
At this stage police say there is no evidence to suggest the child’s mother killed her and they will not be pursuing her unless new information comes to light.
