How did detectives solve the case of the bloody fingerprints? - Theodore E. Yeshion
TED-Ed
Guided Notes
Key concepts students will learn:
- •
In 1902, detectives in Paris solved a murder case using bloody fingerprints found on a shard of broken glass, marking the first time fingerprints alone were used to solve a crime in Europe.
- •
Patent prints are left by transferable substances like blood or dirt, while latent prints are composed of water, oils, proteins, and salts that require dusting or chemical developers to be seen.
- •
Investigators compare minor fingerprint details, such as how the ridges branch and intersect, and the spacing of oil pores, but the system isn't infallible and is prone to human error.
