How does forensic evidence help track and catch criminals?
Where ever you go, what ever you do, you always disturb your environment. Whenever you walk into a room you either leave something or take something with you on the microscopic level. There are hundreds of microscopic pieces of evidence that can link you to specific place at a specific time. Naming a few being DNA trace, fingerprints, hair, sweat, saliva, skin even the brand and chemical make up of the cologne you were can link you to a crime scene. Hours of chemical analysis of a crime scene can bring up hundreds of pieces of evidence that can narrow down suspects. Though the process may not be as fast as you see on CSI: Miami, the idea of it is dead on. Throughout the next 18 weeks of research I hope to better understand how is it that getting away with a crime is technically impossible, thanks to forensic evidence.

What do you think is the most important type of evidence and why?
ReplyDeleteForesic science is a topic that has always had me wondering, "Why would a criminal risk trying to perform a crime if it can usually be traced back to them by forensic evidence?" When Abby Sciuto, the forensic specialist in Naval Criminal Investigative Service (NCIS) finds a key fact in an investigation, I always get excited to hear her explanation, even if the speed at which she found evidence isn't necessarily possible yet. This topic continues to draw my attention as I watch more and more crime shows, and I hope to one day be able to perform the tasks that real forensic specialists today accomplish.
