Forensic science is a widely explored topic, featured in television shows and books, however there are many unseen faults to this “science.” Can it be considered a science despite its faults? That is a question often asked by experts, and maybe that’s a question that should be asked in our everyday lives. People are often wrongfully convicted due to the lack of precision within forensic science, it changes people’s lives by allowing the guilty to go free and the innocent to rot away in jail for…

When conducting a preliminary investigation for a criminal case there are many precise steps that need to take place. "A preliminary investigation is a process that includes all of the activities a responding officer performs at the scene of the crime (Study.com)". There are approximately 6 steps (give or take) in a preliminary investigation; each as important as the last. The first two steps involve providing first aid and scanning the scene. The third and fourth steps consist of determining…

Forensic scientists have an important role during a criminal investigation; they are the ones who analyze biological, chemical, contact trace materials, and physical samples. The samples are taken into evidence to provide proof the police need to make a case in the court. It is the forensic scientist’s job to identify and provide conclusions based on the tests they run on the piece of evidence. Most laboratory examiners who work for the police often find themselves under heavy prosecution bias…

prescription pills might be able to lead us to whomever purchased them. So, we let forensics rap up, and leave. The road was a long one, taking us to a pharmacy at the edge of town. “Hello,” said the man. “Hi, I’m Detective Soos, and this is Detective Moos,” I say motioning to us respectively. “I’m John, a pleasure…

In order to determine the sequence of events that occurred at a crime scene it is important to be able to determine and identify certain bodily fluids versus non-human substances. Based on the location of the biological evidence and its DNA can provide crucial information about the crime scene, its victim, and the suspect(s). These tests divided between presumptive and confirmatory testing. Blood evidence is the most common type bodily fluid found at a crime scene. Presumptive testing at the…

Faces to the Lost,” has both literal and figurative meaning. In this title we found out that forensic anthropologists literally do reconstruct a new face from the skull. The artist tries to get it as accurately as possible using clues from the skull, crime scene, and their knowledge of anatomy. Figuratively they give them a figurative face. This would include a story, a face, an identity. When forensic anthropologists reconstruct a face they are literally giving the deceased person a face.…

A popular television show, “CSI”, is impacting not only the viewers, but also the criminal justice system. On the show, a crime is investigated, analyzed, and a conviction is made in an hour. While the span of the show may be a few days to a few weeks, in reality some investigations take months, even years, before a conviction. It has created a phenomena known as the “CSI Effect” and is basically exactly what it states. How has this television show, “CSI”, played an impact on the criminal…

“Blood is one of the most significant and frequently encountered types of evidence associated with the Forensic Investigative of death and violent crimes” (James, Kish, and Sutton, 2005 p. 1). A Bloodstain Pattern Analysis is called when bloodstains are found at a violent crime scene. The Bloodstain Pattern Analysis discipline has been in existence for a long time, as early as the late 1800’s. “Bloodstain Pattern Analysis focuses on the analysis of the size, shape, and distribution of…

this evidence at a criminal trial under South Australian law?” Blood. Sticky, hot, messy, awful blood. For most of us, the sight of it turns the stomach, but in the court of law, blood can tell a lot more about a crime scene than you might think. Forensic bloodstain pattern analysis (BPA) is the interpretation of bloodstains for the purpose of reconstructing the events that took place in the case of violent crimes.1 Using the sciences of fluid dynamics and trigonometry, BPA examiners form…
