Valentine's Day massacre, Al Capone spent nearly a year in prison on weapons possession charges, getting out in March of 1930.

And in June 1930, Al Capone's brother, Ralph, was sentenced to three years in federal penitentiary for income tax fraud.

Capone, perhaps realizing that he'd better deal with his tax bill, in September of 1930, he has his lawyer submit a letter to an internal revenue agent.

What did this letter say?

How did Capone miscalculate so badly?

So he makes some admission of income.

Surely he's not actually telling the truth.

So the noose is being drawn around Al Capone's neck.

And if we take the movie The Untouchables as gospel, we would think that Elliot Ness is the guy who hunted Al Capone down.

But from your research, it seems that we should be talking about Frank Wilson.

Who was he?

So then how did Elliot Ness become the name we remember?

Much of it was exaggerated.

You mentioned revenue investigator Frank Wilson as the perhaps true hero in the capture of Capone and the break he got in finding this one ledger.

I'd love you to give us a little more detail about the story behind this ledger and then how a ledger led to Capone's arrest and conviction.

Something that we don't really know about this indictment of Capone is that it was a bit of a race against the clock because there was a statute of limitations for filing charges.

How close did they cut it?

So U.S.

Attorney George Johnson announces the indictment of Al Capone on charges of income tax evasion.

And it seems that Capone and his lawyers still think that this is mainly a money issue because they cut a deal in return for a guilty plea.
