Henley was a Half Cherokee American from Texas. He moved to the British colony in
1862 because of the
Cariboo gold rush. He worked with
William Brady, another American, as a hunter providing game meat to restaurants in
Victoria. The two men planned to move north to work in the
Cariboo gold fields.
Henley and
Brady were joined by a group of First Nations people while camping on
Pender Island. The group believed that
Brady had tried to poison them, so they shot at the pair while they were sleeping.
Brady later died of his injuries. Henley was a reportedly large man and was able to fight
them off, though he was seriously injured. Henley then went to
Victoria where he gave
this statement to British authorities on 13 April. Three First Nations men,
Oalitza,
Stalchum and
Thalatson, and one woman,
Thask, were then captured and tried for the murder. Henley testified at their trial.
