Crime scene investigators investigate different types of crime scenes such as home invasions, burglaries, sexual assaults, and homicides. There are different types of crime scene investigator jobs, including criminologists, forensic scientists, and those who specialize in tool marks and firearms. These jobs require long hours and a high school diploma and a four-year college degree, preferably in criminal justice.
As the title implies, a crime scene investigator is called upon to investigate different types of crime scenes such as home invasions, burglaries, sexual assaults and homicides. However, this position involves working as part of a team of crime scene specialists that includes a lead investigator who oversees the collection and handling of evidence. There are also several different types of crime scene investigator jobs, each focused on a different specialty.
The most general of the crime scene investigator jobs is the criminologist. This individual is trained to process a crime scene in terms of dusting and processing fingerprints, identifying and preserving physical evidence, and photographing the scene. As with other work in this field, the criminologist contributes to a crime scene analysis, preparing relevant documentation to support the most likely theory or conclusion about the events that occurred. In addition, that individual may testify in a court of law regarding the procedures used during fact-finding in the case.
Additional crime scene investigator jobs involve forensic science. In this specialty area, the investigator attempts to reconstruct the crime scene and the events leading up to the crime, particularly in the absence of evidence or evidence that is not readily available through common collection practices. For example, a forensic criminologist may be required to extract latent or distorted fingerprints and biological fluids from the skin and other body tissues using special chemicals or laser technology. They can also collect and analyze textile and hair fibers, as well as any botanical material found on site. Additionally, they can convey impressions left in place by foot traffic or tire tread.
Another specialty that falls under crime scene investigator jobs is the collection and analysis of evidence related to tool marks and firearms. However, those working in this capacity are often consulted later in the investigation and generally do not participate in the collection of evidence at the crime scene. Instead, they may be given knives, guns or other tools found at the scene suspected of being used to commit the crime in question. The area of focus in this work is examining the specific marks left by the object in terms of length and depth, as well as determining the distance and direction in which the impact was made. This position also usually involves tracing the serial numbers of weapons, as well as restoring those that have been deliberately obscured.
Most jobs related to crime scene investigation are generously compensated in terms of salary and benefits. However, many crime scene investigator jobs also require long hours and are available at any time, regardless of the time of day or night. In terms of preparing to become a crime scene investigator, a high school diploma and a four-year college degree, preferably in criminal justice, are required. Additionally, some investigative units require individuals to be sworn police officers before proceeding to the crime scene investigation.
