Case evaluation is when a plan of attack is created to determine the order of steps the investigator is to take to collect information effectively. Collecting evidence falls to investigators. This may involve finger printing, picture taking, chemical testing, finding weapons, and other things. It is best for this to be done quickly as evidence can deteriorate and become unusable. Preserving evidence is crucial to building a case. After physical evidence is collected it can be compared with other information obtained from a history or memories of witnesses to find consistencies or inconsistencies (Heartland Forensic Pathology, LLC., 2014).
A forensic lab will create an analysis from the evidence collected. The lab will test for chemicals, DNA samples, traces of blood, bite marks, scratches, and more. The forensic analysis can help identify the victim and the suspect or suspects. Forensic analysis uses different equipment for testing such as microscopes, fume hoods, chromatographs, and spectrometers (Heartland of Forensics, 2014).
Lab procedures produce results from the evidence collected from the lab and the crime scene. A possible suspect is identified. This process is not foolproof thought it will give investigators a direction to go and point to possible suspects who may be innocent of the crime. Suspects are brought in for questioning and interrogation. Interrogation will help determine if the suspect or witness is lying or telling the truth. The information obtained by interrogation can help to pinpoint a suspect.
When there is enough evidence to charge a suspect, the potential guilty suspect will go to trial where crime scene investigators will testify about the case findings using forensic science evidence. This evidence is a major part of a criminal trial. The goal for a criminal investigation is for evidence to prove a suspected criminal guilty.
Educational Requirements and Earnings
An educational requirement divaricates by employer. Most crime labs require a bachelor’s degree though some rural agencies require only a high school diploma to work in a forensic lab. For non-uniform applicants should obtain a four year degree in forensic science or natural science. A degree in natural science or forensic science degree will allow technicians to work in crime labs in subdivisions such as biology and chemistry.
Forensic scientists and technicians should have...
