Jack Kennedy

In June 1938 (Act No. 1) Clark Kent overheard word of a mob attacking the county jail, after applying for a job at the Daily Star. As Superman, he stopped the mob and began questioning the prisoner, who insisted:

"I'm being held for the murder of Jack Kennedy. But I didn't do it... and neither did Evelyn Curry, the girl who's being electrocuted tonight for it!"

Learning that someone named Bea Carroll was responsible for the crime, Superman forcibly took her to the governor's mansion. After being denied entrance, Superman smashed down the door, entered the governor's room through another steel door, and stopped Evelyn Curry's execution, with the real murderer's confession in hand. Thus, the true murderer of Jack Kennedy was revealed and the innocent suspects released (Note: an expanded version of this story appears in S No. 1/1, Sum 1939).
