Here the abandoned ruffian boasted of what he had done, and settled down for a brief time to the customary enjoyments of the rough when in town. He spent his money, hired out as a Danite, killed a couple of men whom the Mormons wanted removed, and soon got so bad that he had to leave. Once more he headed west to California, and once more he started back north from San Francisco, for reasons satisfactory to himself. While in California, as was later learned, he undertook to rob and kill a man at an outlying ranch, who had taken him in and befriended him when he was in need and in flight from vengeance. He showed no understanding of the feeling of gratitude, no matter what was done for him or how great was his own extremity.
In Oregon Helm went back to robbery as his customary means of support, and he killed several men at this time of his life, how many will never be known. In 1862, as the mountain placers were now beginning to draw the crowds of mining men, it was natural that Boone Helm should show up at Florence. Here he killed a man in cold blood, in treachery, while his enemy was not armed, and after their quarrel had been compromised. This victim was Dutch Fred, a man of reputation as a fighter, but he had never offended Helm, who killed him at the instigation of an enemy of his victim, and possibly for hire. He shot Fred while the latter stood looking him in the face, unarmed, and, missing him with the first shot, took deliberate aim with the second and murdered his man in cold blood.
This was pretty bad even for Florence, and he had to leave. That fall he turned up far to the north, on the Fraser river, in British Columbia. Here he was once more reduced to danger on a starving foot march in the wilderness, and here, once more, he was guilty of eating the body of his companion, whom he is supposed to have slain. He was sent back by the British authorities, and for a time was held at Portland, Oregon, for safe keeping. Later he was tried at Florence for killing Dutch Fred, but the witnesses had disappeared, and people had long ago lost interest in the crime by reason of others more recent. Helm escaped justice and was supposed to have gone to Texas; but he soon appeared in the several settlements which have been mentioned in the foregoing pages, and moved from one to the other. He killed many more men, how many in all was never known.
