Sons Turn to Crime
Born in 1872 in Missouri as Arizona Donnie Clark, Ma Barker and her husband George had four sons, Herman, Lloyd, Fred and Arthur (nicknamed “Doc”). She went by a series of nicknames, with members of the Barker gang calling her “Kate.” It’s likely that her perceived role as the maternal figure of the group earned her the nickname “Ma.”.
George worked infrequently and the family was poor. As the boys grew older they became involved in petty crime and then more serious offenses. George left the family and Ma stuck by her sons as they spiraled into a life of lawlessness.
“By 1923 all four Barker boys were either in jails or reformatories. Ma Barker worked tirelessly to get them out, which was an endless job, as the brothers were constantly in and out of prison all of their short lives,” The Encyclopedia of Oklahoma History and Culture states.
In the early 1930s, Fred and Doc Barker teamed up with Karpis, a shrewd and calculating criminal who would later become the gang’s mastermind.
A Safe Place for Criminals
They eventually settled in St. Paul, Minn., a safe haven for gangsters thanks to local law enforcement’s willingness to turn a blind eye to their criminal activity in exchange for bribes, according to historians.
In the gang’s early years, they pulled off a series of crimes, including bank robberies and auto thefts. In 1931, two robbery attempts went sour, leading to the murder of law enforcement officers in Arkansas and Missouri.
In 1933, the group shifted its focus to a different kind of crime, targeting wealthy businessmen during the time of economic despair, knowing that monied families would pay to ensure their loved ones’ safety.
In June, they abducted William Hamm Jr., the president of Hamm’s Brewery in Minnesota, and secured a ransom of $100,000 (nearly $2.5 million in 2025 dollars).
Months later, they struck again, kidnapping banker Edward Bremer, receiving a $200,000 ransom (nearly $5 million in 2025 dollars).
These crimes brought the gang national notoriety and put its members in the crosshairs of federal officials and J. Edgar Hoover, who ran what was then called the Bureau of Investigation. It would be renamed the FBI in 1935.
J. Edgar Hoover Zeros in on the Gang
In the aftermath of the high-profile abduction and murder of the baby son of famed aviator Charles Lindbergh in 1932, kidnapping across state lines became a federal offense.
For the ambitious Hoover, the Barker-Karpis gang’s spree couldn’t have come at a more pivotal time, just as he was seeking to justify his agency’s role in combating crime. The gang’s activities made kidnapping a high-profile crime that Hoover used to justify increasing the agency’s financial and personnel resources to make the bureau America’s premier law enforcement agency.
As Hoover ramped up his war against organized crime, the Barker-Karpis Gang became one of the FBI’s top targets, and his agents used new breakthroughs in forensic science and fingerprint tracing to bring the group to justice.
Karpis went into hiding and on January 8, 1935, and Doc Barker and a fellow gang member were arrested in Chicago, with Doc’s fingerprints linking him to the Bremmer kidnapping, according to FBI accounts of the case.
While high-tech forensics for the time implicated Doc in the crime, it was dumb luck that gave the Bureau its next break. In the apartment where Barker was staying, officials found a map on which Doc circled the location of a lake in the Florida Everglades community of Ocklawaha. That led agents to Fred and Ma’s hideout, a two-story vacation waterfront cottage.
Ma Barker Killed in Shootout
Agents swarmed the hideout on January 16, 1935, and a hours-long shootout ensued. When the gunsmoke cleared, Fred and Ma Barker were dead.
According to Hoover, Ma died with a Thompson submachine gun in her hands, defending Fred to the bitter end. Whether she actually fired a weapon remains a point of contention. Barker was 61.
But their deaths marked the collapse of the gang. Doc was sent to the former penitentiary on Alcatraz and fatally shot during an escape attempt in 1939. Karpis was captured in 1936.
Before the shootout, Ma Barker had drawn little attention from law enforcement as a central figure in the gang. But after her death, Hoover characterized her as one of its criminal masterminds. Some believe he was justifying agents' violent killing an elderly woman, while others say the details of his agents confronting what Hoover characterized as a hardened criminal elevated the agency's image.
Karpis was sentenced to life in prison and would eventually become the longest-serving inmate at Alcatraz.
In later interviews and in his memoirs, Karpis repeatedly insisted that Ma Barker had no active role in the gang’s crimes, describing her as a harmless, clueless figure who enjoyed the comforts of their criminal earnings, but played no role in planning or executing any of the crimes.
She was “just an old fashioned woman from the Ozarks," Karpis noted. “With her personality, brains and style, it was impossible for Ma Barker to ever become the mastermind of the Karpis-Barker gang.”
That did little to stop the media from repeating the story of a ruthless, gun-toting matriarch leading a band of killers.
For decades after her death, Ma Barker was the public face of the gang, a symbol of moral decay and maternal failure. Some contend that while she might never have pulled a trigger, she was nonetheless complicit in the crimes themselves.
