Who killed Sam Giancana? Reply to soon revealed – NBC Chicago

The question of who killed Sam Giancana, an assassination attempt that has long seen as one of the greatest hits of Chicagos has not been answered for a long time.

The answer behind his assassination is the last family secret of the Chicago Outfit, a secret NBC 5 investigations now knows.

Our investigation team dug into the long -hidden case and spoke to those who once spoke in the mob and those who examined the murder from outside. We searched law enforcement files, photos and laboratory reports and asked the police, prosecutors and mob numbers to determine who committed the crime.

Here is what you need to know about the case:

Who is Sam Giancana, also known as 'Momo'?

Giancana was a mob legend in Chicago and led the outfit from the late 1950s to the mid -1970s. His mob pointed name was “Momo”, short for Mooney, also known as crazy.

“Giancana was a very influential person in the outfit,” said Douglas Depodesta, who is responsible for the FBI Chicago.

“He was with one of the McGuire sisters,” added Depodesta. “He hung around with the rat package. Of course there was a lot of attention at that time.”

Giancana was born in Chicago in 1908 and quickly became aware of the attention of the powerful chicago outfit founded by Al Capone, an unshakable crime syndicate that he finally joined in the late 1930s. Giana's advancement to the dominance of organized crime and national fame in the late 1950s, when he became the head of the outfit, followed by years of conspiracies that Giancana and his employees associated with a number of top -class crime, including President John F. Kennedy, in 1963 in 1963.

After Giancana had a year in prison for a year in prison for a conviction, he fled to Mexico in 1966, but was returned to the USA only eight years later and returned to Chicago.

He was a notorious Chicago outfit Don, whose gangland -adattattary remained a mystery 50 years ago. The investigative reporter Chuck Goudie has discovered crime scene photos and new details this decades.

What happened to Momo?

Fifty years ago, in the spring of 1975, Momo was in his house in West Vorstadt -Oak Park and lived in a basement apartment.

He had just returned from the gallbladder surgery in Houston, and some friends were over to welcome him at home.

Before 11 p.m. there was a visitor to someone who was familiar with Giancana apparently enough to allow a cellar staircase.

The hoodlum began to make a late -evening snack. Giancana stood above this pan, sizzling sausage and escarole with beans when his house guest fired a shot from this silencer, 22-caliber pistol directly into the back of Giancana's head. And then after the Mobster collapsed, six other shots in his mouth and symbolize the golden rule of the outfit: You shouldn't talk.

“Whoever it was, was professional enough to know that they wanted to make sure he didn't survive,” said the Reformed Chicago Mobster Frank Calabrese, Jr.

Calabrese Jr. has MOB -DNA in the blood. His father Frank “The Breeze” Calabrese, Sr., was a Chicago criminal boss and an outfit -hitman.

In 1975, when Giancana said in front of the US intelligence agency, some syndicate insiders may have been nervous about whether he canceled his vow from Omerta or secret and were too much meaningful about relationships between the mob and the central intelligence agency. Motif enough for murder.

“The world of chicago outfit and organized crime is a dirty, evil little world,” said Mobologist John Binder, who said that there are numerous murder -suspect in the mob goal, but never enough evidence of law enforcement.

“There are different claims about different people, credible claims to a certain extent, more or less about who may have killed Giancana,” said Binder, who wrote a book about the mob in 2003, “The Chicago outfit.”

“I think the most likely version of events is that it was Butch Blasi,” said Binder. “He was there that night. There was a small party in Gancana's house. Contains two outfit people: Blasi and Chuck English.”

Does the Chicago outfit still exist in 2025? NBC 5 examines Chuck Goudie finds out the answer.

In his house in Chicago – and the crime scene

Police photos of Giancana's actual residence – and what would become a crime scene – have never been shown publicly before.

There are framed illustrations of circus clowns that decorate its office wall and a stand-up bag cup on site that the depot for its cigar stolates. And there is a hardline house phone in which the 67-year-old Giancana crime-syndicate business led.

A photo shows how Chicago Police Detective has monitored the gangster bungalow, confirmed by a police report we received. But NBC Chicago Sources say what the report is not in the dead of the night.

Possible suspects

Chuckie English was a chicago outfit boss boss, who would be murdered later for a decade. He was never charged and not Dominic “Butch” Blasi, Giancana's long -time bodyguard and Wheelman.

All over the country in the Mob Museum in Las Vegas, where Giancana is a prominent face on the wall, said outfit expert Jeff Schumacher that the death of Momo confused the detectives from the first day.

“There are suspects. There are theories. But they know that it will be quite difficult at this time,” said Schumacher, Vice President of Museum Exhibitions and Programs.

Who actually did it?

In part two of “Who Tötung Momo” we go to the Giancana Police files. NBC 5 Investigates revisited the evidence that the weapon followed, examined who showed up in the dead of the night and discovered the name of the man who did it.

Who pulled the deduction? And why is this man never charged?

In the second segment of this exclusive report, the NBC 5 Investigates team will expose the murderer.

The segment is to be broadcast on NBC Chicago on Thursday at 10 p.m. Take a look at yourself on TV or stream it in the player above.
