When you think of the Wild West, Hollywood’s glittering legends – the Wild Bunch, the Dalton Gang, Billy the Kid’s Regulators – probably spring to mind. Yet there’s a shadowy roster of outlaw bands that never got a silver‑screen makeover. This top 10 fascinating roundup shines a light on those forgotten crews, the ones whose deeds still echo in dusty trail stories and hidden treasure lore.
Why This Top 10 Fascinating List Matters
10 The Rio Grande Posse
The Rio Grande Posse, operating in the 1870s and 1880s, earned the alternate moniker John Kinney Gang after its commander. Kinney, a former U.S. Army soldier discharged in 1865, turned his martial experience to a life of cattle rustling and highway robbery. Among his ranks were future heavy‑hitters like Jesse Evans, who later formed his own outfit, and Charles “Pony Diehl” Ray, who eventually rode with Curly Bill Brocius in the infamous clashes against the Earp brothers.
Kinney’s gang carved its most dramatic moment in 1878 when it threw its weight behind the Lincoln County War, directly opposing Billy the Kid’s Regulators. Legend has it that Billy managed to shoot off part of Kinney’s ear during a ferocious gunfight. After the war, some men stayed loyal to Kinney, while others defected to Evans’ new gang, reshaping the outlaw landscape of New Mexico.
The posse’s downfall arrived in 1883 when Kinney was apprehended for cattle rustling. By the time he secured his release, his compatriots were either dead, imprisoned, or scattered. Rather than return to crime, Kinney re‑enlisted for the Spanish‑American War, closing the chapter on a notorious outlaw career.
9 The Bummers
The Colorado Territory’s criminal tapestry includes a low‑key crew known as the Bummers, led by the boisterous Eddie “Shooter” Coleman. Unlike the high‑profile rustlers of the era, the Bummers were a rag‑tag collection of loafers, petty thieves, and chronic drunks who set their sights on the mining settlement of Auraria, now part of modern‑day Denver.
Operating in a legal vacuum—Auraria had yet to be formally incorporated—the Bummers exploited the lack of law enforcement. Their nighttime antics involved loud revelry, heavy drinking, and a barrage of celebratory gunfire designed to intimidate respectable townsfolk and assert their dominance over the fledgling community.
Their reign of mischief culminated in the infamous “Turkey War” of Christmas 1859. After the Bummers pilfered a farmer’s wagon brimming with birds meant for holiday feasts, the outraged townspeople formed a vigilante posse. A violent clash ensued, resulting in the death of one Bummer and the lynching of several others. The surviving members fled, their criminal chapter effectively closed.
8 The Innocents
The Innocents occupy a murky spot in Montana’s gold‑rush history, alternately painted as a savage highway gang or as unwitting pawns of a ruthless vigilante faction. Their story hinges on the disputed legacy of Sheriff Henry Plummer, who allegedly led the group in a spree that claimed over a hundred lives before a self‑styled justice squad put an end to their reign.
According to the classic narrative, the Innocents preyed on gold‑laden travelers, robbing stagecoaches and murdering anyone who crossed their path. Plummer’s corruption allegedly enabled the gang to operate with impunity, culminating in a wave of executions where members—including the sheriff—were hanged from trees after swift, sometimes non‑existent trials.
Modern historians, however, question the cohesion of this supposed gang. While records confirm a spate of robberies and murders across Montana during the 1860s, concrete evidence linking them to a single organized group remains thin. Moreover, the alleged victims were allegedly dismembered, buried, burned, or dumped beneath ice, yet none of their remains or stolen treasure have ever been recovered.
The narrative persisted largely because it was chronicled by respected contemporary sources, notably Thomas Dimsdale, Montana’s inaugural newspaper editor, whose work The Vigilantes of Montana cemented the tale. Even today, the story sparks debate; during a 1993 posthumous trial of Plummer, the jury deadlocked 6‑6, resulting in a mistrial that underscores the enduring ambiguity surrounding the Innocents.
7 The Jennings Gang
The Jennings Gang offers a cautionary tale that not every outlaw can thrive in the lawless West. Formed by former attorneys Al and Frank Jennings, the group briefly attracted attention by recruiting the erstwhile Wild Bunch member Richard “Little Dick” West. Their criminal career, however, spanned merely a few months in 1897 before collapsing under the weight of their own incompetence.
Based out of Oklahoma, the Jennings attempted a series of robberies targeting trains, general stores, and even a post office. Their luck was abysmal: one store yielded a meager $15, and a train heist resulted in an empty safe being blown up. The gang’s bungling culminated in swift arrests, with only “Little Dick” managing to escape before meeting his own violent end a year later.
Al Jennings’ story took an unexpected turn after a five‑year prison stint. Granted a presidential pardon in 1907, he pivoted to politics, securing the Democratic nomination for Oklahoma County attorney in 1912 and campaigning on a platform of transparency that openly referenced his criminal past. Though he lost the election, his notoriety landed him in Hollywood, where he appeared in over two dozen silent films, including the 1914 biopic Beating Back. He later threw his hat into the gubernatorial ring, finishing third in the Democratic primary, cementing his legacy as a multi‑faceted, if not entirely successful, public figure.
6 The Red Jack Gang
The Red Jack Gang prowled the Arizona frontier in the early 1880s, preying on stagecoaches that traversed the San Pedro River corridor. Their charismatic leader, “Red Jack” Almer, earned his nickname from his striking ginger hair and a pallid complexion that gave him an almost ethereal, sometimes feminine, appearance.
Among their daring exploits, the most celebrated was the August 10, 1883 robbery of a Florence‑Globe stagecoach hauling a Wells Fargo strongbox brimming with gold. Almer allegedly boarded the coach as a passenger to verify the presence of valuable cargo, then either slipped away before the heist or stayed on board to signal his accomplices. A colorful legend adds that Almer, leveraging his delicate looks, once donned a dress to masquerade as a woman, further deflecting suspicion.
The loot—thousands of dollars in gold—vanished without a trace, fueling endless speculation. However, the gang’s success attracted relentless pursuit. Lawmen, including Sheriff Bob Paul, a confidant of the famed Earp brothers, tracked the outlaws, culminating in a gunfight that claimed Almer’s life and marked the gang’s eventual dissolution.
5 The Ketchum Gang
Tom “Black Jack” Ketchum, pictured above, launched his criminal career alongside his older brother Sam in the mid‑1890s. Their notoriety surged with rumors linking them to the 1896 disappearance and presumed murder of Texas Senator Albert Fountain and his eight‑year‑old son, Henry. A bloody confrontation that same year saw the brothers ambush a store owner, Levi Herzstein, whose posse suffered a fatal casualty before the outlaws escaped.
As the Ketchum Gang expanded, they turned their sights to trains and stagecoaches, recruiting future Wild Bunch members such as Ben “Tall Texan” Kilpatrick and Harvey “Kid Curry” Logan. In 1899, Sam led a successful train robbery without Tom, but a pursuing posse forced a ferocious gunfight that left several gang members dead, including Sam himself.
Undeterred, Tom attempted a solo train robbery, only to be recognized by the conductor, who blasted his right arm off with a shotgun. Captured and sentenced, his execution turned into a macabre spectacle when the rope snapped, causing his head to detach in front of a stunned crowd—an ending as theatrical as the outlaw’s life.
4 The Dodge City Gang
Unlike many of its contemporaries, the Dodge City Gang set its sights on political domination, seeking to control the burgeoning town of Las Vegas, New Mexico, through a blend of corruption, intimidation, and outright violence. Their reign lasted only a few months in 1879, but during that window they wielded considerable influence.
The gang was led by Hyman Neill, better known as “Hoodoo” Brown, who parlayed his reputation as a gunslinger into the position of justice of the peace, promising to eradicate corruption while secretly installing his fellow outlaws into official law‑enforcement roles. Joe Carson became chief of police, “Mysterious” Dave Mather took the deputy marshal post, and Dave Rudabaugh served as a regular policeman.
Carson’s tenure was cut short when he fell in a shoot‑out, and the gang’s criminal activities—robberies and intimidation—continued unabated. Eventually, deputy John Sherman rallied an honest contingent of men, catching the crooks in the act. Most were arrested; Mather was acquitted and later built a fearsome reputation before vanishing from the record. Hoodoo Brown, though not directly implicated in the robbery, was driven out of town by an angry mob aware of his machinations.
3 The Jack Taylor Gang
Active across the Arizona Territory and into Mexico during the mid‑1880s, the Jack Taylor Gang earned a fearsome reputation for brutality and lightning‑quick draw speed. Their most chilling feat involved a single train robbery that left four passengers dead, followed by separate incidents that claimed the lives of four additional crew members.
The gang’s downfall began in 1887 when leader Jack Taylor was seized by Mexican Rurales and sentenced to life imprisonment. The remaining members—Manuel Robles, Fred Federico, Geronimo Miranda, and Nieves Deron—fled back to Arizona, drawing the attention of Cochise County Sheriff “Texas” John Slaughter. Slaughter’s posse raided Robles’ brother’s home in Contention City, where a gunfight resulted in Deron’s death and Robles, though wounded, escaped to regroup with Miranda and Federico.
The trio’s final chapter unfolded later that year. Robles and Miranda were killed in a shootout with Mexican Rurales, while Federico, after shooting a deputy sheriff, was captured and swiftly hanged. Their violent saga sealed the gang’s legacy as one of the era’s most ruthless outfits.
2 The McCanles Gang
The July 21, 1861 showdown at Rock Creek Station, Nebraska, entered legend as the McCanles Massacre. Some accounts describe three men defending themselves against a vicious outlaw gang, while others argue the McCanles Gang never truly existed, suggesting the three men perpetrated cold‑blooded murder to erase a debt. Regardless, the incident cemented Wild Bill Hickok’s early fame.
David McCanles, owner of the land on which the station sat, allegedly led a trio—including James Woods and James Gordon—to collect payment from station manager Horace Wellman. When Wellman could not furnish the full amount, McCanles purportedly turned violent, attempting to kill the manager. Hickok and another stock tender, Brink, intervened, resulting in a shootout that left McCanles and his two associates dead. Hickok faced murder charges but was later acquitted.
A competing narrative, recounted by McCanles’ 12‑year‑old son Monroe, claims his father and his men arrived unarmed and were gunned down without provocation by Hickok, Wellman, and Brink. The story adds that Wellman tried to crush Monroe with a hoe, missed, and the boy escaped, underscoring the event’s contested nature.
1 The Reynolds Gang
The Reynolds Gang remains shrouded in mystery, yet its tale is undeniably captivating. Formed by Confederate soldiers Jim and John Reynolds, the outfit targeted stagecoaches traversing Colorado’s Kenosha Pass, occasionally resorting to bloodshed. Some historians argue the gang operated under Confederate orders, siphoning loot to fund the Southern war effort.
By July 31, 1864, a determined posse caught up with the gang, sparking a gunfight that claimed one outlaw’s life while five others were captured. Only John Reynolds and Jack Stowe evaded capture, fleeing into New Mexico. The captured men’s fate is contested: official reports claim they perished during a botched escape, yet Confederate sympathizers allege they were chained to a tree and executed on Colonel Chivington’s orders—the same man behind the Sand Creek Massacre.
Seven years later, John Reynolds partnered with Al Brown. After a deadly shootout left Reynolds mortally wounded, he allegedly whispered the location of his hidden treasure to Brown. The latter searched Mount Logan, but a landslide had altered the terrain, concealing the loot forever. Treasure hunters continue to scour the area, hoping to uncover the long‑lost bounty.
