States that there are no two fingerprints that are exactly alike,”

an American “public enemy number one” criminal who attempted to erase his fingerprints with the use of ACID but failed

gained the fame as the “man without fingerprints” after knowing from an inmate of a possible destruction of fingerprints. He removed the skin up to the generative layer and served thin into incisions on each side of Pitts chest.

Performed painful experiments on themselves by burning their fingertips with boiling water and oil with hot metals to find out whether it can destroy the ridges of a finger. After the healing of epidermis, the original patterns of fingerprints reappeared.

States that Fingerprinting is one of the most reliable means of personal identification

is only applied to high profile and celebrated cases. It is also applied when fingerprinting is not applicable

KINDS OF FINGERPRINT POWDER

METHOD OF DETECTING PRINTS

This is done with the use of fingerprint brush and powder by applying amount of powder that is lightly swept on the suspected area to little by little reveal the print caused by the powder.

The powder is put on the suspected surface of a material/object. Then in slanting position, the material/object is rolled slightly to attach powder in the fingerprint.

The powder is put into an empty container specially designed for spraying.

The latent print is powdered and lifted ready to be pasted to a paper with opposite color from that of the color of powder used.
