Conley handled Zorin's oil interests in the East Bay. He was later contracted to assist Zorin on Project Main Strike in San Francisco.
Once the time had come to flood the fault, Conley realized that Zorin planned to turn on his own men. He protested, but Scarpine stuck Conley over the back of the head and he fell into the mine. Zorin then detonated the hidden explosives and flooded the mine, killing Conley and his workers.
