Stock owner John Brown was speared eight times in his left side and hutkeeper Joseph Lovelock was speared through the heart. Both men died of their wounds. Interpreter Clamor Schürmann obtained the Aboriginal version of events, namely that Mordalta speared Lovelock in order to rob the hut, and that Brown was speared by Ngarbi.

On hearing that Aboriginal people had assembled at Port Lincoln Proper, Hugonin, accompanied by Hawson and Bishop, sailed to the location. Landing a mile away from where smoke was seen on the shore, the Europeans surrounded the group. Hugoinin’s men shot two people, fired several shots at the rest, and burnt ‘a good number’ of spears.

On 10 May 1843, about 40 or 50 Aboriginal people appeared at Edward McEllister’s station. They stated that they were Biddle’s murderers, and that they would kill him if he did not leave the station. McEllister retreated to his hut and fired on them from a port-hole. The Aboriginal group threw stones at the roof and took two axe heads. One man finally dropped from the effects of McEllister’s shot.

When Ngarbi was apprended by T Hawson on 11 May 1842, between twenty to thirty of his Countrymen threatened Hawson. They did not attempt a rescue. Ngarbi admitted his involvement in the confrontation at McEllister’s station the previous day, and was known to be one of those involved in the murders at Rolles Biddle’s station in March 1842.

Ngarbi was found guilty for the murder of Elizabeth Tubbs at Port Lincoln on 29 March 1842. He was hanged at the Adelaide Gaol on 1 August 1843.
