Crime Scene Investigations: Everything You Want to Know But Were Afraid to Ask

Everything you wanted to know about crime scene investigations but were afraid to ask. 

Our students are mesmerized with CSI Cleveland and all other television shows showing beautiful young people solving crimes using the latest technology. There are two things to keep in mind. The first is that the CSI series and its clones are such complete fiction that they are hard to watch (at least for us) and second, crime scene investigation is dirty and complex work that most people wouldn’t touch with a ten foot pole. 

Having said that, it impossible to persuade students from the subject. With that thought in mind, the National Institute of Justice of the US Department of Justice offers a complete array of material covering virtually all aspects of crime scene investigation. For all you budding investigators, enjoy!

Forensic Sciences

Forensic sciences play a vital role in the criminal justice system by providing investigators with scientifically based information through the analysis of physical evidence. 

During an investigation, forensic evidence is collected at a crime scene, analyzed in a laboratory and often presented in court. Each crime scene is unique, and each case presents its own challenges. Complex cases may require the collection, examination and analysis of a large amount of evidence. These cases may involve multiple forensic experts with backgrounds in biology, chemistry, physics, computer science and other disciplines. These forensic scientists work separately to analyze the evidence in a particular case. For example, one forensic examiner might analyze a latent print, another may compare carpet fibers using a microscope, and a third may identify a white powder that was collected at the scene. The investigators will then combine all of the examiners’ objective results to build a case.
