"Big" Steve Long (died October 28, 1868) was a western lawman and outlaw, achieving notoriety in the Wyoming Territory during the late 1860s. He was one of the earliest examples of an Old West gunman. Because of their lawlessness, he and two half-brothers were lynched by a posse put together by a newly appointed sheriff in 1868.
Little is known about Steve Long's early life or childhood. After the American Civil War, he had settled in Laramie, Wyoming. He and his half-brothers, Ace and Con Moyer, established a saloon together in the railroad town. Both Ace and Con helped found Laramie. Long reportedly had spent several years as an early version of a gunfighter before being elected in 1867 as Deputy Marshal of Laramie.
It is believed that Long had served during the Civil War, in the Confederate States Army, but under a different name. He migrated to Wyoming around 1866.
Long soon earned a reputation as a particularly violent lawman, killing eight men in gunfights within two months. On October 22, 1867, Long opened fire on eight men during a street brawl after his orders to cease were ignored, killing five of the men. He rarely arrested anyone, choosing instead to either intimidate them with the threat of force or shoot them.
Long and his brothers used their forceful personalities and his position as the Deputy Marshal to their own financial advantage. Within months of his gaining that position, they had forced several local ranchers to sign over to them the deeds to their properties. Several of those who refused were later confronted while alone by Long, who killed them, always claiming later that the other man had reached for a weapon. If the victim was not carrying a pistol or rifle, Long would place one on his person after killing him. There were never any witnesses. It is alleged that Long killed at least nine men in that fashion during a four-month period. Local residents called the saloon the "Bucket of Blood" because of the violence that often happened inside.
By October 1868, Long had killed thirteen men. Another seven men had been killed under suspicious circumstances, with Long suspected, but his role was never confirmed. There was no evidence to support his being named as the killer in these incidents. Long made little effort to find the alleged murderers, leading to speculation that he had committed those murders. Each of the seven men had been known to have refused to sign over land deeds to Long and his brothers.
