For a few short months the gang embarked upon a crime spree along the west coast of the South Island that would culminate in the murder of five men on the Maungatapu Track.
Hokitika
Burgess stole two revolvers from the Hokitika police camp on 10 May. He staged a 'discovery' of these guns at a nearby beach in the presence of two witnesses, Sullivan and a man called Chamberlain. A search of his room located the stolen weapons but his witnesses helped him escape any charges. The Hokitika police supplied the local press with details of his Dunedin history and advised Burgess and Kelly to leave town.
Without bodies the case was circumstantial. On 22 June 1866 searchers found the dead packhorse and the missing men's swags. Rewards for information were offered in vain, but a breakthrough occurred when the government promised £200 and a free pardon to any accomplice (not the actual murderer) who would turn Queen's evidence. This reward poster was placed where the prisoners could see it.
When Joseph Sullivan returned to Hokitika to give evidence about the robbery of the Hokitika police camp and the murder of George Dobson, a mob called for him to be lynched. Chamberlain was sentenced to four years for perjury in the case of the stolen revolvers; one of the accused police 'insiders' was acquitted. James Wilson was acquitted for the murder of George Dobson; the jury indicated that Sullivan was the most likely killer.
'Even before the famous Maungatapu murders in 1866, swaggers were looked upon with distrust on the West Coast, and after that date hardly any one travelled in those parts without carrying a small revolver in his breast-pocket.'
