How Crime Scene Investigators Work with Investigators to Solve Crimes

For the successful resolution of crimes, it is necessary for investigators to work with crime scene investigators (CSIs) to process the crime scene. CSIs enter get to the crime scene first and record it before it is contaminated. They record the scene through photographs, sketches, and videos, process the scene, and gather and preserve evidence. Investigators review the scene after the CSIs record it. Investigators help in identifying evidence that should be gathered and analyzing it. The term paper explores how CSIs and investigators work together in solving crimes and highlights several examples of cases that have been successfully resolved as a result of this cooperation. CSIs and investigators work together to solve crimes as the former gathers and records evidence, while the latter analyzes the collected items to get clues about the people involved, how the crime occurred, and the weapons used.

A CSI performs a systematic examination of crime scenes to find physical evidence that helps in identifying what occurred and the people who were involved. They work together with investigators on crimes such as burglaries, fires, vehicle accidents, violent crimes, auto thefts, and suicides. They gather evidence depending on the type of crime. Crime cases are investigated by investigators or detectives who follow leads, interview persons of interest, and piece together information using the evidence gathered at the scene (National Forensic Science Technology Center (NFSTC), 2013). The investigator works alongside a team of CSIs to search the crime scene and gather evidence. The CSI team may include evidence gathering professionals and crime scene photographers.

At the scene of crime, CSIs work together with investigators to perform several activities, including defining areas that may contain evidence and securing them, inspecting and documenting the scene, gathering physical evidence, and maintaining, packaging, and presenting it for analysis in a laboratory (NFSTC, 2013). Crime scene investigations are based on Edmond Locard’s Exchange Principle, which states that every perpetrator leaves and takes something from a crime scene (Baxter, 2015).
