Does anyone know how much time did Frank Costello actually serve in prison for his tax evasion convictions? In most of the articles it's said he was convicted and acquitted on appeal several times on the same charges. Here is a quote from the book "Treasury agent" by Andrew Tully, writted in 1958s:
On May 13, 1954, Costello was convicted on three counts of willful tax evasion — for the years 1947, 1948 and 1949. He was sentenced to serve five years on each of the counts, to run concurrently, and was fined $ 10,000 on each count — a total of $ 30,000. Costello appealed to the second circuit court of appeals, which upheld the 1948 and 1949 convictions but reversed the 1947 finding and reduced his fine to $ 20,000. Subsequently, the Supreme Court upheld the finding of the circuit court.
So what was the final penalty? The initial one was 5 years, what was the one handled down by the Supreme Court and how much did he actually serve?
