Lindsey Graham

That same year, on Valentine's Day, several members of Moran's gang were found gunned down in a garage.

The crime shocked the city, and Capone and Moran's rivalry led many to suspect that Capone had ordered the hit.

Facing unprecedented public outrage over the crime, authorities became determined to get Capone however they could.

But lacking any real evidence to tie him to the murders, they knew they would have to take an unconventional approach if they were to have any hope of putting him behind bars.

This is episode two in our two-part series on the St.

Valentine's Day Massacre.

Public Enemy number one.

Imagine it's a little after 1030 in the morning on February 14th, 1929.

You're the leader of one of the biggest gangs in Chicago, and you're sitting in the front seat of a black sedan while a colleague sits behind the wheel.

You're beating your fingers impatiently on your thigh as the driver waits for a delivery boy to cross the street carrying an armful of cut flowers.

You reach across and honk the horn.

Come on, move it.

Let's go.

Give the kid a break.

It's Valentine's Day.

Probably his busiest day of the whole year.

Well, I'm busy too.

Your day is packed.

Right now you're supposed to be meeting a truck full of stolen liquor, but you're running late.

Finally, the delivery boy moves out of the way.
