HIS STORY: UNSUNG

Mike Malone wasn’t just another agent —he lived among Capone’s men, at risk of exposure every single day.  He gathered the evidence that led to the downfall of the most notorious gangster in American history. Yet when the dust settled, his name disappeared from the headlines. Instead, the FBI took the glory. History moved on. And Malone’s story was nearly lost.

This is a small sample of the more than 150 cases Mike Malone worked during his career, spanning political corruption, organized crime, Prohibition-era enforcement, Hollywood figures, tax-evasion matters, and nationally significant investigations.

  • Teapot Dome and the Albert Fall investigation
  • Exposure of hundreds of corrupt Prohibition agents (1920–1927)
  • The Al Capone investigation
  • Other notable organized-crime figures, including Waxey Gordon, Dutch Schultz, Lucky Luciano, Leon Gleckman, Enoch “Nucky” Johnson, and Moses and Walter Annenberg
  • Major Hollywood figures, including Charlie Chaplin, Tom Mix, Marion Davies, William Fox, Irving Thalberg, Ringling Bros., and Marjorie Berger
  • The Joe Nunan tax-evasion case
  • The Lindbergh/Hauptmann kidnapping case
  • Huey Long

Taken together, these cases show the remarkable breadth of Malone’s investigative work. He pursued corruption at the highest levels of government, helped expose misconduct within Prohibition enforcement, and played a role in using tax law to bring organized-crime figures to justice. His work also reached into prominent entertainment, political, and kidnapping investigations, reflecting a career defined by undercover skill, financial investigation, and service on some of the most consequential cases of his era.

THE ATTIC DISCOVERY

For decades, our family thought Uncle Mike’s life had been forgotten. Then, hidden away in an attic, we uncovered government-issued IDs, personal letters, and Treasury Department documents that rewrote history. 

What we found revealed a man who risks everything – without ever asking for recognition.

TIMELINE – FROM
CAPONE TO TODAY

Mike Malone infiltrates Al Capone’s empire, gathering the evidence that would topple a criminal titan.

Decades later, Uncle Marty discovers Malone’s hidden documents in the attic – a story nearly lost to history.

Al Capone’s name resurfaces in headlines when President Donald Trump references him, claiming he has been investigated or indicted more times than Capone. These modern mentions underscore the enduring place in American culture—and why Malone’s story feels surprisingly relevant today.

DID YOU KNOW?

Mike Malone was assigned to the notoriously high-profile Lindbergh Baby Kidnapping case. His diligent work and contributions to the extensive investigation ultimately played a significant role, leading to the successful conviction of the Lindbergh Baby Kidnapper.

Relying on documented public information, the family now brings the private legacy life story of the man who brought Al Capone to justice to the public. The entire US criminal justice system failed in this mission, as ordered by President Hoover. One man stood out from all the rest, but this quiet hero desired only to share the fame and glory quietly with his law and order compatriots and family. Mike Malone's family invites you to learn about our beloved Uncle Mike.
