Forensic science is misleading because it suggests only one type of science is involved, but this is not the case. Forensic investigations can involve virtually any field of science and technology. There are many steps that have to be taken when leading a criminal investigation and investigating a crime scene. Firstly, detectives have to try and figure out why and how a crime was committed. They examine a crime scene looking for information or clues such as fingerprints, weapons, and DNA. They investigate the victims’ history to define why someone would want to harm them. After they have formed a hypothesis, they try to find proof that somebody committed a crime so that they can arrest the suspects. They look at both the cause and the actual evidence of the crime and try to see if their hypothesis makes sense. The suspects then enter the criminal justice system where they are tried using the evidence collected at the crime scene. Forensic investigations require skills of specially trained scientists, police, engineers, doctors and others. “These investigators observe all types of evidence, from weapons to bloodstains and from computers to bugs” (Erzinclioglu 5). The greater the evidence against a person, the greater the chance of conviction. Homicide detectives usually work in pairs and approach a crime scene with five basic questions: Did the death take place at the crime scene or elsewhere? Was there any attempt to alter the crime scene? Does the scene point to any particular activity such as drug abuse or burglary? Is the cause of death obvious? Are there sufficient clues pointing to how the death occurred? “Scene processing is the term practical to the series of steps taken to investigate a crime scene.

Fingerprints are a guaranteed method of identification because each person’s fingertips are unique and fingerprints don’t change throughout a person’s lifetime. Fingerprint ridges appear in three pattern types; loop, whorls, and arches. The most collective type of fingerprint pattern, loops begin at one side of the fingertip, double back, and exit on the same side. Whorls are the second most common type of fingerprint pattern. They form a circular pattern which sometimes look like a bull’s-eye on a dartboard. Arches are less common than loops and whorls. They form a wavelike pattern which begins on one side of the fingertip and ends on the other.

- Explains that forensic science is misleading because it suggests only one type of science, but this is not the case. detectives have to figure out why and how a crime was committed.
- Explains that forensic investigations require skills of specially trained scientists, police, engineers, doctors, and others. the more evidence against a person, the greater the chance of conviction.
- Explains that murder detectives usually work in pairs and approach a crime scene with five basic questions: did the death take place at the crime site or elsewhere?
- Explains that the term "scene processing" refers to the series of steps taken to investigate a crime scene.
- Explains that crime investigation begins at the place where the crime was committed. the area must be secluded and secured to prevent the destruction of critical physical evidence that can lead police to link the criminals to the victim.
- Explains that the first police officer is responsible for preventing other non-crucial police workers and citizens from entering the scene and often establishes a border around the crime scene with ropes or tapes.
- Explains that forensic photographers take pictures of the crime scene and provide a permanent record. sketches, videos, and notes are used as visual evidence, but only photos are presented in court.
- Explains that the crime scene technician is a professional in discovering and identifying physical evidence. the scene and each bit of evidence is carefully photographed and then properly collected and trained to avoid contamination.
- Explains spiral searches are for crimes that happen in small areas, for example, a house. they start from inside the room where the crime occurred and then spread outwards.
- Advises that all evidence taken from a crime scene should be protected, so that it is not contaminated, damaged, lost, or broken. items should not be picked up by bare hand unless gloves are worn.
- Explains that document analysis covers the physical, chemical, and structural properties of papers and inks.
- Explains the differences in inks used for identification and aging, such as the chemical and dye combinations used to make them.
- Explains that experts believe that no two individuals write exactly the same. people may write in very similar styles but each has an individual way of forming and joining letters. disguised writing makes style characteristics even harder to detect.
- Explains that forensic examiners analyze differences in typed or mechanically printed documents. typewriters used a particular typeface or font.
- Explains that document examiners don't need visible print to link a person or machine to crime. they can use any marks left on the paper.
- Explains that audio or sound analysis can provide vital clues in forensic science. it can pick up faint background noises or conversations that can help identify a speaker.
- Explains that forensic investigators are always looking to improve the way they compare images of identifying evidence, such as shoe prints, faces, and fingerprints with simple held on databases.
- Explains that fingerprints are a guaranteed method of identification because each person's fingertips are unique and fingerprint ridges appear in three pattern types; loop, whorls, and arches.
- Explains loops and whorls are the most common types of fingerprint patterns. they form a circular pattern which looks like bull’s-eyes on dartboards.

Before evidence can be touched a primary survey is conducted where the lead investigator will take notes, take their own pictures, and identify what they consider to be valuable evidence. Another thing the lead investigator does is to make sure the conditions are recorded such as if the lights were on or off, position of furniture, smell, etc. Pictures and/or videos are taken of the scene by a crime scene team. Sometimes a quick sketch is drawn of the crime scene to ensure that everything is accounted for.

I will be looking at this timeline and other cases that have occurred over the years that fit onto it throughout this discussion. In early 275BC, the ancient Greeks and the Romans were the first people to practice forensic science; however they didn’t have much knowledge and were using their own ideas and assumptions to solve smaller crimes. For example, Archimedes discovered ways to determine the volume of an object and used his theory to demonstrate this. He realised that his body weight displaced equal amounts of water. Here we can see early forensic science and what it consisted of in the past; it was insignificant and didn’t usually find clear or accurate

There is also another group called biological evidence. Biological evidence branches from a living thing, including bloodstains and DNA. Forensic scientists place their evidence into categories including these. “Forensic science is the use of scientific principles and methods to analyze material connected with a crime” (Funkhouser). When a crime is committed, law enforcement officers tape off the scene as quickly as possible (Funkhouser). They then search the area for evidence (Funkhouser). Forensic scientists rarely actually go to the crime scene (Funkhouser).
