Treasure Chest of Fun and Fact #6 [494]

In "The Proof is in the Print," Sgt. Reilly guides two unnamed boys from the safety patrol through the surprising history of fingerprinting, revealing how pioneers like Johannes E.

With the help of Commissioner Herschel, the story traces how these scientific minds laid the foundation for modern forensic work—long before the first crime scene photos were taken.
