New technology promises quick assault

Dutch forensic experts have found a way to accurately determine the time of the fingerprints at the scene, a breakthrough in the near future that would allow police to crack down on cases that occurred a few years ago. .

Although not the 'Holy Grail' in the field of fingerprints, Marcel de Puit of the Dutch Institute of Forensic Medicine (NFI) stresses that this is a very important discovery, and also the first method. Determine when the fingerprints appear at the scene.

"The achievement means you can determine when the suspect is on the scene, or pinpoint fingerprints related to the investigation ," AFP quoted De Puit as saying.

Previous attempts to decode the fingerprint time-defining formula failed because experts focused on the amount of chemicals instead of analyzing their correlation when configuring. so fingerprint characteristics.

Based on ambient temperature, which can affect the speed of fading of the fingerprint, forensic experts can now determine the time of fingerprints within 1 to 2 days and dark. The maximum is 15 days.

New techniques need to be tested extensively at crime scene sites, which form the database before being used in the prosecution process, and experts hope to soon apply this finding within the 1 more year.
