The big change in the investigation industry is due to the rare story of two guys

Thanks to these 2 guys, the investigation industry in the world today is somewhat . a little easier to breathe.

One of the most used factors in investigation cases today is fingerprints.

Basically, each person has a separate fingerprint, so fingerprints are one of the important proofs to determine the appearance of a person at a certain time, and sometimes even evidence. accusation.

However, fingerprints are not always used. For centuries, the investigation investigation industry has absolutely no reliance on this tool. In the early 20th century, things changed suddenly because of an extremely rare story between the two guys in the picture below.

Look at 1, but actually 2 different people.

The rare story opens the revolution in the investigation industry

In fact, since 1880, science has known about the difference between each person's fingerprints through the study of Henry Faulds. However, it has never been considered an important factor, even when Britain used it in 1901.

It all changed in 1903, when an American prison met a different "twin brother" prisoner . of his father.

Specifically, in 1903, a guy named Will West was arrested and brought into Leavenworth prison. At that time, US prisons had not used fingerprints, but used a more common identification process than the Bertillion system (created by the French anthropologist Alphonse Bertillion).

Prisoners in prison will be photographed and checked with the Bertillion system, and of course Will West is no exception. However, during the inspection, they discovered that Will West had identical parameters to another offender who was serving a life sentence for murder.

The names of two people are almost identical.

Their appearance is almost the same, but even the name almost matches: Will West and William West.

Can not distinguish both to store in the file, the experts must finally take fingerprint samples to compare and take it as a base.

Fingerprints.

Also since then, it has been realized that using only the Bertillion system is not enough, but more accurate and reliable identification elements are needed. After 1903, many American prisons began applying fingerprints, and this method also spread to the whole world.
