Fingerprints can be lifted from crime scenes today within seconds when it was almost impossible to in the past.
Some other technological advances that have been facilitated in the field of forensic sciences are the use of chemical agents and laser technologies that help investigators while trying to identify blood and other bodily fluids even after they have been cleaned from surfaces. I think that this is a big advancement because it doesn't matter what the assailant does to try and cover his tracks by way of cleaning up blood or bodily fluids, the chemicals are going to recognize the characteristics of the specimen and identify it with help of the laser lights. The use of this technique will provide investigators with information about the victim, the assailant, and possibly the position in which the victim was when attacked according to blood spatter patterns.
Advancements in locating and collecting physical evidence has seemed some improvements but many more improvements have come in the analysis of evidence also. I wrote about fingerprinting... [continues]
