Police are set to reveal a new development in a nearly three-year-old investigation into the murder of prostitute Mellory Manning this afternoon.
Detective Inspector Greg Williams has called a media conference at 2pm to speak about a "development in evidence'' relating to the murder.
Ms Manning's extensively injured body was found dumped in the Avon River on December 19, 2008.
Investigators believe Ms Manning was attacked at a large section on Galbraith Avenue, which was being used by the Mongrel Mob at the time of her murder.
Mr Williams earlier said forensic evidence had linked Ms Manning to the address.
"This site is very close to where the victim's body was located in the Avon River,'' he said.
Mr Williams said timings in the case suggested that Ms Manning's attackers would have had previous knowledge of the site.
