Police investigating the murder of Canberra artist Eden Waugh have recovered a firearm from the Queanbeyan River.
ACT Policing said a crow bar was also recovered and forensic officers would now examine the two items.
Eden Waugh was shot dead in his Watson home on 3 November last year.
Police last month charged a 29-year-old Karabar man with accessory to the murder of the 37-year-old artist but are still following several lines of inquiry to bring the killer or killers to justice.
They have now concluded their search of the river and surrounds.
It involved officers from AFP Search and Rescue, Forensics, Maritime Divers, NSW Police and ACT Policing Criminal Investigations, as well as volunteers from ACT and NSW SES and ACT Rural Fire Service.
ACT Policing is urging anyone who was in the area of the Queanbeyan River near River Drive, Karabar on the weekend of the 4-6 November 2016, and may have seen anyone acting suspiciously to contact Crime Stoppers on 1800 333 000 or via https://act.crimestoppers.com.au. Information can be provided anonymously.
Rewards of up to $1000 may be applicable for information provided to Crime Stoppers that assist in apprehending an offender or solving a crime.
