Crime Scene Investigations
Everything involving a crime scene begins at the scene of the crime. The crime scene is where the accident/incident took place. There is to be no evidence destruction so the first officer on duty is to protect the scene and establish some kind of perimeter so that the all the evidence remains on the scene until a crime scene investigator investigates. There are many things to do when investigating and there are many things to look for when going through the process of crime scene investigation; one being forensic biology, trace evidence, and of course impressions mainly known as fingerprints.
One of the things the investigators look for is the obvious, which is physical evidence. Physical evidence is exactly what it sounds like, it is any physical material left around the scene of the crime. The physical evidence is to be proven or disproven. Physical evidence has the potential to prove how the crime may have been committed. IF the body is on the scene another thing that needs to be done is to identify the body or the name of the victim. Then hopefully the investigator will have some kind of link on a suspect weather it’s from the body or anything on the scene itself. Physical evidence can range from anything big or anything small basically it is anything that can be touched, moved, or picked up. Physical evidence then brings me to another big thing that is called forensic biology. Forensic biology preforms DNA analysis on any fluids to decipher identification. A lot of forensic biology is found at the larger crime scenes or more violent crime scenes. The things that are collected at crime scenes are from things that are physical evidence. These things include blood, semen, salvia, or anything that is a fluid. The DNA of one of these types of fluids will then link to an identification of a suspect. Sometimes at a crime scene there will be evident strands of hair, or nail particles that is also considered forensic biology and will...
