Disgraced Victorian police officer Paul Dale allegedly paid underworld killer Carl Williams A$150,000 ($188,000) to hire a hitman to murder an informant in a case against him.
The trial of Williams' cellmate for his murder heard Williams gave the money to an associate, who killed informant Terence Hodson, due to testify in a corruption case against Dale.
The revelation is in a written statement Williams gave police two months before he was killed in Barwon Prison last year by Matthew Johnson, who is pleading not guilty on grounds of self-defence.
Hodson and his wife, Christine, were killed at their home in Kew in May, 2004, before Dale's committal hearing.
"Dale told me he had to get Hodson before his committal," Williams said in the statement. "Dale said he had someone on the job, but they were taking too long. He asked me if I could help him out."
