Fisch supplied the ransom money, while Hauptmann was uninvolved in the abduction

Hauptmann claimed that Isidor Fisch had left him a box containing the money. This offered an alternative explanation for possession of the notes, but the jury rejected the defense and the appellate court upheld its assessment alongside the wood, writing, and witness evidence. Fisch had died and was never tried.
