In late 1864, during the robbery of a mail coach near Jugiong, Gilbert shot and killed Sergeant Parry.

While Hall and Gilbert were holding up the hotel, Dunn shot and killed the local police officer.

Hall had separated from the other two and later was surrounded by police in the bush near Forbes, New South Wales, and shot dead.

Senior Constable Charles Hales of the Binalong police station received information at 8pm on 12 May 1865 that the two bushrangers had "stuck up" the woolshed near Murrumburrah.

Hale immediately gathered constables John Bright and Michael King and headed out to watch Kelly's house.

The next morning at 8am John Kelly (under the influence of alcohol) informed Hales that Gilbert and Dunn were at his hut.

Hales gathered constables John Bright, Michael King and Henry Hall and headed to Kelly's place.

[3] Back in custody, the law took no chances and with little mercy put Dunn on a dray bound for Sydney.

[1] He was buried in the Devonshire Street Cemetery, which was cleared and the dead reinterred elsewhere to make way for Central Railway Station.

John Dunn appears as a major character in the 2016 feature film The Legend of Ben Hall,[7][8] portrayed by Melbourne actor William Lee, who was cast partially due to his resemblance of the outlaw.

[9] The film depicts Dunn's recruitment into the Ben Hall gang, his romantic involvement with Margaret Monks and the murder of Constable Nelson at Collector.
