In order to apprehend a criminal the first steps involve evidence collection. CSI technicians collect blood samples either by submitting a piece of clothing or by using a sterile cloth and a small amount of distilled water to remove some blood from the body as well as collect blood samples by scraping trace blood spatter from walls and floors into a sterile container using a scalpel. Blood samples are also collected from the body. These samples are then sent to be analyzed to determine if the samples are the same since any blood at the crime scene may belong to either the victim or assailant. The lab will perform DNA analysis on the sample as well as the victim to determine whether or not it can be used later to compare to blood taken from all suspects.…

It was used in the trial to test skin to determine the sex of the person and if then to see if the dead persons body part in the cellar were Coras. They tested Coras great niece to compare thier DNA.…
4. Evidence is important to forensic science because it helps solve the crime and it contributes DNA to find the criminal. The evidence important in the episodes was the broken glass, the green goo, and mostly the blue dog beer can.…
Evidence at a crime scene, such as blood, DNA, fingerprints, or shoeprints all help forensic investigators determine what might have occurred and help identify or exonerate potential suspects.…
3. Police officers, crime scene investigators and others in the justice system rely on forensic science techniques to ensure that the right people are punished for law violations and to keep people safe. Fingerprints are starting players in the criminal offense and defense lineup. They are so important to criminalistics that justice officers still use fingerprint systems over a hundred years after scientists developed them.…
Forensic evidence has been used since the beginning of investigating. It could be anything from ammunition, to a handprint on the door, to the drops of blood on the crime scene. As seen in “Forensic Evidence” by Andrea Campbell, the indisputable forensic evidence is the best kind to use in a trial.…
As a Crime Scene Investigator (CSI), there are duties that have to be met and a job that has to get done. Part of this job is looking for evidence. There are different types of evidence. Some can be seen with an unaided eye and some can't. Trace evidence cannot be seen with an unaided eye. Every person who is physically involved with a crime leaves some kind of trace evidence such as hair, fibers, and even have gunshot residue left on the perpetrators hands. It is even possible to obtain a confession from the suspect .…
When they arrive at a crime scene after everything happen they have to look after evidence such as: blood and other body fluids, hairs, fibres from clothing, paint and glass fragments, tyre marks, flammable substances used to start fires, analysing fluid and tissue samples for traces of drugs and poisons, analysing handwriting, signatures, ink and paper, recovering data from computers, mobile phones and other electronic equipment. Most of the evidences are usually presented in writing as a formal statement but the forensic scientists may have to go court to give their evidence in person.…
Forensic scientists collect and analyze the evidence, give an expert testimony, and train other law enforcement individuals on how to record and collect evidence.…
1. It is important to use proper methods while collecting evidence from a crime scene because evidence is extremely important in solving a crime, and improper collection could corrupt the entire investigation. Evidence may become contaminated if proper methods are not used, which could severely effect analysis outcomes. Additionally, specific procedures must be followed for evidence to be used in a court room. Therefore, it is extremely important to gather evidence with proper methods in order for that evidence to be useful in a court of law.…
-Brief Description- Forensic scientist’s help investigators solve crimes by analyzing the pieces of evidence that have been gathered from a crime scene. They might work with a wide variety of evidence types, or specialize in an area such as DNA evidence or fingerprint examination.…
In the criminal justice investigation process forensic science and the scientific method are used. The collecting of the evidence is a very important procedure and should be done with…
Evidence can be as diverse as people; however, when looking to collect any type of evidence, it will typically be separated into one of two categories: real evidence or testimonial. Real evidence is considered to be tangible, such as, it will be anything that the five senses can perceive (Worral, Hemmens, & Nored, 2012, p. 71). Articles of clothing, weapons, contracts or legal documentation, and photographs are all examples of tangible / real evidence. Additionally, within this same category of real evidence, “demonstrative” evidence will also be included. This type of evidence would be anything that can actually demonstrate the crime and/or scene. For example, a technician…
Forensic evidence is a type or forensic science, which is a science applied to answering legal questions. This evidence can draw together knowledge from a single field, or it could be a combination of fields. Whatever the field may be, the evidence is applied and used to help reconstruct a crime case. There is also a branch called Criminalistics, which deals with the examination…
Now in order for them to do this they have to first do a walkthrough of the scene to determine what strategy they will need to use in order to apprehend evidence from the scene (work.chro.com. n.d.). They also need to figure out what equipment and resources will be needed to collect the evidence during their walkthrough of the crime scene. Furthermore, they document the crime scene and all of the evidence that has been collected at the crime scene in order to later be able to testify in court that the evidence in question is from that scene and has been properly documented and collected.…
