Latent Fingerprints on Wet Surfaces. In most cases criminals are concerned about not leaving any traces at the crime scene. Therefore, it is common to burn exhibits or throw them into water (e.g. plastics, bottles, foils etc) with the intention to wash all fingerprints away.
In this manner, can fingerprints last in water?
Therefore, fingerprints were examined at different intervals; 1, 2 and 10 days. In the present work, either in sea or fresh water, the duration of submersion in water has its effects with a marked diminished quality of fingerprints in longer duration (10 days).
One may also ask, can fingerprints be wiped off? Barring some extraordinary science that has escaped me, yes. Wiping down almost any surface will at least smear any latent fingerprints that may be there. Wiping down almost any surface will at least smear any latent fingerprints that may be there. The prints will be difficult, at best, to recover and identify.
Then, can fingerprints wash off in the rain?
Sweat consists mainly of water (98% – 99.5%). If the weather had been inclement, I would expect the mark to be “washed away” due to the effects of the rain and, therefore, the mark would appear faint on the lift. The sweat from the fingerprint is mainly made up of water and would evaporate and fade in the sun.
