Introduction Forensic investigations: defined by applications of principles to matter (Merriam, 2019). Examined through analytical techniques; procedures for analysis of facts, issues, or status- generally are tasked and time-limited (ManagementMania, 2016). However, with increased effectiveness- accuracy of findings will intensify and limitations will decrease. Chromatography is a technique used within forensics- separating components of a chemical mixture relying on the differential affinities of substances for a mobile and an absorbing, stationary medium which they pass (Farlex, 2020). This fundamental concept:...

Rationale Forensic chemistry is the application of chemistry, forensic toxicology, in a legal setting. A forensic chemist can assist in the identification of unknown materials and instruments found at a crime scene. Forensic Chemists have a wide array of methods used to identify unknown substances including High performance liquid chromatography (HPCL), gas chromatography (GC), atomic absorption spectroscopy, Fourier transform infrared spectroscopy, and thin layer chromatography. These different types of methods are important due to the critical nature of some instruments...

Discovery and development of forensic genetics took a long time and required a lot of field practice. After the discovery of the ABO blood types, scientists start to use blood groups in identification for forensic genetics. In 1910, the French criminologist Edmond Locard proposed the Locard’s exchange principle and stated that “every contact leaves a trace,” which laid the foundation for modern forensic science (1). In 1953, the discovery of the double-helical structure of DNA enabled the start of forensic...

This laboratory only had a small number of personnel working there at six, a possible reasoning for this would be that Forensic Science was a new area of advanced science which had not been discovered back in that time era. The Home Office opened several laboratories across England and Wales under the...

The origin of DNA fingerprinting was discovered in 1984 by Dr Alec Jeffreys (Jackson and Jackson, 2011, p. 158). Over the decades, with technical developments in genetics, the original DNA fingerprinting procedure has undertaken a variety of modifications and refinements. DNA profiling has become so precise and sensitive that in the United Kingdom it is no longer allowed to be used as a sole piece of evidence in a criminal investigation, it has to be used alongside other procedures. Nevertheless,...

The subject of criminology is often seen as more of a scientific field and the popular media that engages with crime sources their material from crimes that had occurred or theories that engage with deviance and criminology. However, the emergence of forensic semiotics have placed a new emphasis on the study of the relationship between criminology, forensic sciences, and the portrayal of crime in popular media. The study of forensic semiotics can contribute significantly to the study of crime detection...

Introduction Forensic Science is the study of civil and criminal law, which can be broken down into many categories. Forensic Odontology is specifically important because teeth are composed of enamel, one of the hardest biological substances in the human body, they are very well protected by soft tissues in the body, for example, the tongue (PMC 2018). Teeth can also survive immersion, decomposition and direct heat in excess of 1000 degrees Fahrenheit (PMC 2018). Forensic Odontology is used to solve...

Mitochondrial DNA (mtDNA) analysis is becoming more common in criminal investigations to characterize forensic biological specimen. This paper will examine mtDNA analysis in the forensic field, the expertise and training required and its strengths and limitations. The strengths of mtDNA analysis are the following: mtDNA has a high copy number, it provides an alternative option when nuclear DNA (nucDNA) is not viable, better recovery from degraded samples, confirms maternal relatedness and some discriminatory power using hypervariable regions. The limitations of...

When a crime has been committed the factor of handwriting, fingerprints, and DNA are used in a process which looks to confirm the identity of an individual and a link between the crime scene and origin of reference. Element traces like fingerprint contribute to a criminal investigation in the form of methodological or scientific indication through different procedures. The first step is called identification that determines what is at the crime scene, bullet deposit, blood and/or hair. After that is...
