A homicide investigator or homicide detective investigates suspicious deaths and collects and evaluates evidence to determine the cause of a homicide. [1] [2] [3]
Homicide investigators begin their work by investigating the crime scene to identify and secure evidence. They set the parameters of the crime scene to prevent public interference, ensuring the preservation of both the evidence and the scene itself. After the initial inspection, they reach out to known witnesses and search for potential witnesses in the vicinity of the crime scene. Revisiting the scene is common, as investigators re-inspect the area to identify any evidence that might have been missed during the initial investigation. [2]
Homicide investigators aim to deliver justice by holding the guilty accountable and protecting the innocent from wrongful accusations. Their duties often include:
A detective is an investigator, usually a member of a law enforcement agency. They often collect information to solve crimes by talking to witnesses and informants, collecting physical evidence, or searching records in databases. This leads them to arrest criminals and enable them to be convicted in court. A detective may work for the police or privately.

A cold case is a crime, or a suspected crime, that has not yet been fully resolved and is not the subject of a current criminal investigation, but for which new information could emerge from new witness testimony, re-examined archives, new or retained material evidence, or fresh activities of a suspect. New technological methods developed after the crime was committed can be used on the surviving evidence for analysis often with conclusive results.
A crime scene is any location that may be associated with a committed crime. Crime scenes contain physical evidence that is pertinent to a criminal investigation. This evidence is collected by crime scene investigators (CSI) and law enforcement. The location of a crime scene can be the place where the crime took place or can be any area that contains evidence from the crime itself. Scenes are not only limited to a location, but can be any person, place, or object associated with the criminal behaviours that occurred.
