According to most biographies that I could find citation needed , the conman Viktor Lustig was sentenced to 15 years in Prison in Alcatraz, got pneumonia in March 1947 and died two days later in Springfield, Missouri. For example, this is what Wikipedia has:
"Lustig pleaded guilty at his trial and was sentenced to fifteen years in prison on Alcatraz Island, California for his original charge, with a further five years for his prison escape. On 9 March 1947, Lustig contracted pneumonia and died two days later at the Medical Center for Federal Prisoners in Springfield, Missouri."
The death certificate was issued in Springfield, so this part is probably correct. What I don't understand why a prisoner would have been transferred some 1900 miles for something "simple" as a pneumonia. There must have been facilities closer by that could have dealt with something like that.
EDIT:
I found some references that mentioned a brain tumor. Reading the death certificate linked above more carefull has:
Immediate cause of death: Pneumonia
Due to: Hemoplegia, probably caused by brain abscess
and
Length of stay. In hospital or institution: 2 months, 12 days
This is a much different case than a simple pneumonia
