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.
