On Sunday morning, September 8, 1935, Long travelled to the State Capitol in order to pass a re-redistricting plan which would oust political opponent Judge Benjamin Henry Pavy.
At 9:20 p.m., just after passage of the bill effectively removing Pavy, Pavy's son-in-law, Carl Weiss, approached Long, and, according to the generally accepted version of events, fired a single shot with a handgun from four feet (1.2 m) away, striking Long in the torso.
Long's bodyguards, nicknamed the "Cossacks" or "skullcrushers", responded by firing at Weiss with their own pistols, killing him; an autopsy found that Weiss had been shot at least sixty times.
Long was able to run down a flight of stairs and across the capitol grounds, hailing a car to take him to the Our Lady of the Lake Hospital.
Long was rushed to the operating room, where emergency surgery attempted to close perforations in his intestines, but ultimately failed in trying to stop his internal bleeding.
Long died at 4:10 a.m. on September 10, 31 hours after being shot.
According to different sources, his last words were either, "I wonder what will happen to my poor university boys," or "God, don’t let me die.
I have so much to do".

Over 200,000 people travelled to Baton Rouge to attend Long's funeral.
His remains were buried on the grounds of the State Capitol, and a statue at his grave depicts his achievements.
Although Long's allies claimed that he was assassinated by political opponents, a federal probe found no evidence of a conspiracy.
Long's death brought relief to the Roosevelt administration, which would win in a landslide in the 1936 election.
Farley publicly admitted his apprehension of campaigning against Long: "I always laughed Huey off, but I did not feel that way about him."
Roosevelt's close economic advisor Rexford Tugwell would later write: "When he was gone it seemed that a beneficent peace had fallen on the land.
Father Coughlin, Reno, Townsend, et al.,
were after all pygmies compared with Huey.
He had been a major phenomenon."
Tugwell also wrote that Roosevelt regarded Long's assassination as a "providential occurrence".

Recent evidence has led some to claim that Long was accidentally shot by his bodyguards.
Proponents of this theory assert that Long was caught in the cross fire as his bodyguards shot Weiss, and was hit by one of the bullets which ricocheted off the marble walls.
