Gene Krupa witness, John Pateakos had been paid to testify falsely against Krupa. Pateakos returned to prove that he wasn't a minor, that he had dodged the draft, and that he had been instructed by federal agents to leave after the first conviction.

In 1973, Krupa died in Yonkers at the age 64 from heart failure, though he also had leukemia and emphysema. He was buried in Holy Cross Cemetery
