charges relating to the murders of Silk and Miller as well as 13 other charges of armed robbery relating to offences alleged to have occurred between March and July 1998. Guilty verdict On 17 February 2003, the trial began in the Supreme Court of Victoria (VSC 30), heard by Justice Philip Cummins. On 23 February 2003, Debs and Roberts were found guilty of the murders and sentenced to life imprisonment. Debs served part of his sentence at maximum security Victorian prison HM Prison Barwon; and, during the 2022 retrial of Roberts, he appeared via video-link from Goulburn Supermax Prison in New South Wales. Operation Gloucester In 2015, the Independent Broad-based Anti-corruption Commission (IBAC) started investigating improper practices during Lorimer Taskforce, but it was closed due to lack of evidence. In November 2017, IBAC reopened Operation Gloucester after new evidence was obtained via media reports supporting the original allegations of misconduct.

It was found that Senior Constable Glenn Pullin destroyed his original statement, submitting a backdated statement instead, indicating that there were two offenders. A fresh trial was ordered for Roberts, running for four months, featuring 90 witnesses, 200 exhibits, and hours of recorded conversations.

In a statement via the police union, the families of the victims said they were "absolutely devastated
