1. INTRODUCTION Forensic science is the application of scientific procedures to help solve criminal and legal matters. At the scene of any crime a variety of physical evidence may be left behind that can link a criminal to a crime‚ or help reconstruct the sequence of events which occurred during that crime. Forensic biologists examine articles and crime scenes for evidence of biological material and attempt to determine the origin of that material by using tests that provides biologically discrimination

Screening tests are those that help a forensic scientist identify several particular drugs that the substance is likely to be. These types of tests are useful when they provide positive results and when they provide negative results‚ since the forensic scientist can then rule out certain types of drugs from the possibilities. 3.) Color tests involve introducing a chemical reagent to the drug

Forensic Toxicology Forensic toxicology plays an exceptionally vital role in linking victim deaths to drug use‚ poisonings‚ and the detection of foreign chemicals and toxins in the human body. The utilization of analytical chemistry and a few chemical tests can tell investigators if the victim was under the influence of any drugs or even poisoned‚ by studying samples of blood‚ urine‚ hair and even bodily fluids. Forensic toxicologists detect and identify the foreign chemicals in the body‚ the

Since psychology involves the study of human behavior‚ it has become a vital role within the judicial system. However‚ the debate concerning the use of clinical psychologists in the courtroom has become a growing epidemic. While many argue that the treating therapist can play both a therapeutic and forensic role‚ what they fail to realize is that the vast differences within the two fields will create more turmoil than good. In clinical psychology‚ for instance‚ the general goal is to identify

responsible for the crime will not be at the crime site when the crime is discovered. Forensic scientists have to rely on the evidence at the scene to piece together who might have committed the crime. Also fires and explosion can cause a great deal of damage to the crime scene. The evidence traditionally found at other crime scenes is likely to be destroyed or damaged at these crime scenes‚ making it necessary for forensic scientists to focus on other types of evidence in their investigation. 2.

When forensics or forensic sciences are mentioned‚ most individuals think about the crime that forensics entails. The gore‚ the blood splatter analyses‚ bullet projections‚ DNA analyses‚ death investigations‚ semen stains‚ bite marks‚ and rape kits to name a few things that involve forensic investigations‚ but those things are just a small part of a much larger picture. Forensics is extremely broad. Forensics is the application of the scientific method and biology‚ chemistry‚ computer science‚ and

Individual characteristics are properties associated with a common source to a high degree of certainty. An example of individual characteristics that forensic scientists may look for are the ridge characteristics of two fingerprint samples. 3.
