Physical decline and death
Capone's control and interests within organized crime diminished rapidly after his imprisonment, and he was no longer able to run the Outfit after his release. He had lost weight, and his physical and mental health had deteriorated under the effects of neurosyphilis. He often raved on about Communists, foreigners, and George Moran, who he was convinced was still plotting to kill him from his Ohio prison cell.
On January 21, 1947, Capone had an apoplectic stroke. He regained consciousness and started to improve but contracted pneumonia on January 24. He suffered a fatal cardiac arrest the next day.
Capone was buried in Mount Olivet Cemetery, in Chicago's far South Side between the graves of his father, Gabriele, and brother, Frank. However, in March 1950, the remains of all three family members were moved to Mount Carmel Cemetery in Hillside, Illinois, west of Chicago.
