The use of fingerprints left at the scene of a crime to identify an offender was first suggested in the nineteenth century,1, 2 and this branch of forensics continues to play an integral role in a wide range of criminal investigations.3 Sweat secretions deposited onto a surface leave an impression of the papillary ridge pattern of the finger, referred to as a latent fingerprint. Latent prints are not easily visible to the naked eye, and various techniques have been developed to enhance andmake…

Results are presented that show practical applications for the enhancement to fingerprints deposited in arson crime scenes, contaminated by spray painting, or deposited on brass cartridge cases prior to discharge.

On the Skin-Furrows of the Hand

IN looking over some specimens of “prehistoric” pottery found in Japan I was led, about a year ago, to give some attention to the character of certain finger-marks which had been made on them while

The effects of time and detonation on latent fingerprints from cartridges and cartridge castings were explored and an interesting technique for development and permanent preservation of latent fingerprint impressions on castridge casings was described.

Latent fingerprint detection using a scanning Kelvin microprobe.

Electrochemical interactions between latent human fingerprints and metal surfaces in ambient air are investigated using a scanning Kelvin microprobe using inorganic salts present in sweat deposited at fingerprint ridges to produce Volta potential differences.

On the electrical characteristics of latent finger mark corrosion of brass

Apparatus constructed to measure the variation (ΔV) in applied potential (V) over the surface of brass discs subject to corrosion by latent finger mark deposits is described. Results show values of
