Trace Evidence

I found a website that discusses fiber and hair evidence analysis.  This article has six different chapters.  The articles are very interesting, it talks about the first time in 1936 that trace evidence was used such as hair and fiber.  It goes on to talk about different cases were hair and fiber evidence were used as evidence.  This article is very insightful.  It gives a lot of detail and information about this topic.  It is also an easy read, which sometimes articles on this topic can be hard to follow.  Towards the end of the article it also talks about different trace evidence that police also can use like glass, dirt, dust seeds and paint.  It goes on to tell the reader how these particular items can lead police to the suspect. My favorite chapter is caught by a hair.  This chapter shows how one piece of hair can make the difference between a case going cold and it going in a new direction.  With this particular case, the hair evidence let police to the killer and a conviction. 

I find it very interesting how such a piece of hair or some dirt can provide so much information for police.  Most killers try to clean up any trace of themselves, but it's hard to notice if a hair fall out or something came off your clothes or shoes.  Without cleaning the room inch for inch, criminals will almost always live some evidence that they were there.  Lucky for us, we can use this trace evidence to find the criminal.
