How do FBI track down serial killers?

Stranger murder is one of the hardest types of murders to solve. But the FBI has put a lot of effort into the indentifing and capture of serial killers. Criminal profiling, although not an exact science, helps decipher psychological clues left by the killer, either on the body or crime scene.

Fingerprints are now compared by computers and any matches take only seconds in some cases. Forensics plays heavily in the detection of the guilty. Fiber, hair, blood, ect are a part of every homicide case.

Even blood that has been cleaned and even bleached can still be detected, in some cases, years after the crime. * And with these advances in science came DNA. The identifing of each individual's genetic material, unique to every person with the exception of identical twins, has taken crime detection into the 21st century.

What 50 years ago was science fiction is now routine police work The above advances have made the detection and capture of serial killers far easier than ever before. But any good cop will tell you that it still takes the human factor to make it all happen. There is no way to replace good old-fashioned police work.

A combination of intuition and experience is the heart and soul of any homicide case With the use of chemicals such as Luminol, blood, even decades old, can be detected.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
