I once worked with the IRS agent who brought Capone down on income tax evasion. Whatever worked legally.
Mr. Little was quite a guy.
My chairman/teacher at NVCC (Police Science), was the rookie FBI agent who received the first phone call from the German saboteur agent Daesch telling about their submarine landing and sabotage missions, and his desire to surrender.
Agent Furcolow was a great teacher too. PS His brother was also an FBI agent. Nice family
Most know the story:
Edward Henry “Butch” O’Hare was born in St. Louis, Missouri to Edward Joseph O’Hare and Selma O’Hare.
Butch had two sisters, Patricia and Marilyn. When their parents divorced in 1927,
Butch and his sisters stayed with their mother Selma in St. Louis while their father Edward moved to Chicago.
Butch’s father was a lawyer who worked closely with Al Capone before turning against him and helping convict Capone of tax evasion.[4]

In 1949, the airport was renamed “O’Hare International Airport” to honor Edward O’Hare,
the U.S. Navy’s first flying ace and Medal of Honor recipient in World War II.
