June 17, 1933. Ninety-three years ago this morning, a group of law enforcement officers walked across Kansas City Union Station at approximately 9:30 a.m. with their prisoner, a notorious federal escapee named Frank "Jelly" Nash. They had every reason to think this was a routine transfer. Seconds later, gunfire erupted from multiple directions. When the shooting stopped — it lasted only moments — four law enforcement officers and the prisoner they were escorting lay dead. The Kansas City Massacre, also known as the Union Station Massacre, had just become one of the bloodiest ambushes in American law enforcement history.
Frank Nash had been a problem for the government since at least 1913, when he received a life sentence in Oklahoma for murder. He proved impossible to contain. On October 19, 1930, Nash escaped from the U.S. Penitentiary at Leavenworth, Kansas — a maximum-security federal facility — and spent the next three years evading capture while continuing a career that included bank robbery and other violent offenses. When federal agents finally ran him down and arrested him in the summer of 1933, they made arrangements to return him to Leavenworth. Special Agent in Charge Edgar C. Vetterli, the FBI's special agent in charge of the Kansas City office, personally coordinated the transfer. There was no sign anything had gone wrong.
The men waiting at Union Station had been busy since the day before. Vernon Miller, a career criminal with a personal stake in the outcome — he was a close friend of Nash's — had organized the rescue operation. He recruited Charles "Pretty Boy" Floyd, one of the most-wanted bank robbers of the Depression era, and Floyd's accomplice Adam Richetti. Their journey to Kansas City had not gone smoothly: their vehicle broke down on the morning of June 16, stranding them briefly before they pushed on. By the morning of June 17, they were in position.
When Nash and his escort moved through the station, Miller, Floyd, and Richetti opened fire from their positions. The attack was over in seconds. Special Agent William F. Caffrey — among the earliest FBI agents killed in the line of duty — died at the scene. Kansas City police officer William J. Grooms was also killed, along with additional officers from other agencies who had participated in escorting Nash. Five people were dead in total: four law enforcement officers, and Frank Nash himself. Despite planning and executing a rescue operation on behalf of their friend, the gunmen had killed him in the crossfire.
The brazen slaughter of law enforcement officers in a crowded public station stunned the nation. The early 1930s had already produced a wave of Depression-era criminals who moved across state lines faster than jurisdictional boundaries allowed local police to track them. But the Union Station Massacre crystallized the stakes in a way that newspaper accounts of distant bank robberies had not. Law enforcement officers had died trying to move a prisoner through a train station on a Tuesday morning.
The investigation mobilized agencies across the country. All three orchestrators of the ambush met violent ends. Vernon Miller was killed in November 1933. Charles Floyd, elevated to Public Enemy Number One in the massacre's aftermath, was shot and killed by FBI agents in October 1934. Adam Richetti was convicted in connection with the attack and executed in 1939.
The Kansas City Massacre became a hinge point in the history of American law enforcement. In the months and years that followed, Congress expanded federal law enforcement authority, giving the Bureau new powers to pursue criminals across state lines and strengthening jurisdiction over crimes against federal officers. The attack at Union Station exposed precisely how lethal the gap between federal and local authority could be — and the political will to close that gap followed. The Bureau of Investigation was reshaped into the modern FBI partly in the wreckage of what happened on June 17, 1933. As recently as 2023, the FBI's Omaha Chapter laid a wreath at Agent Caffrey's grave to mark the ninetieth anniversary of the attack. The officers who fell on that platform have not been forgotten.
