In 1930, Capone was Public Enemy Number One in Chicago.

A year later he was arrested for failure to pay taxes.

The government had finally found a way to catch him.

After a trial, he was found guilty and sentenced to 11 years in prison.

He spent the first two years of his sentence at a prison in Atlanta, Georgia.

Then he was sent to Alcatraz, the country's most famous prison.

At Alcatraz he was diagnosed with a disease that began to take over his brain.

As a result, he spent much of his time in the prison hospital.

By the time he was released from prison in 1939, he was no longer able to lead his organization.

He died of a stroke and pneumonia in 1947.
