A fourth man has been charged over the alleged 2016 murder of 37-year-old Eden Waugh.

Eden Waugh was allegedly killed by a single gunshot on November 3, 2016.

A 23-year-old NSW man will face the ACT Magistrates Court on Saturday, March 16, after being extradited to the territory and charged with murder.

Police found a lifeless Mr Waugh with a single gunshot wound to his chest after being called to a disturbance at a Watson home about 7.25pm on November 3, 2016.

The man will also be charged with two counts of aggravated burglary at Mr Waugh’s house in September and November 2016.

While three people have previously been charged over the murder, one of the men has since had his charge downgraded to being an accessory after the fact and another man has had his charge downgraded to attempt to dispose of evidence.

No further arrests are expected, police said.
