Capone's Vault (S7E5)

Forty years ago, millions of Americans turned on their TVs to watch The Mysteries of Al Capone's Vault. In this live broadcast, construction workers blasted their way into a subterranean chamber beneath Chicago's Lexington Hotel, believed to have been a secret vault that belonged to the crime boss. My guest, William Elliott Hazelgrove, author of the new book, Capone's Vault, tells the story of how this broadcast got made and what investigators discovered underneath the Lexington once the cameras were rolling.
