Who is a Crime Scene Investigator?

A crime scene investigator is a forensic scientist who identifies, assembles, analyzes, and documents evidence discovered at a crime scene. They investigate crime scenes involving robberies, mass killings, sexual attacks, encroachments, and other crimes.

The outcome of their investigation has a direct impact on the criminal and legal prosecution that follows.

Crime scene investigators are also important during trials due to the importance of their expert evidence in the courtroom.

Their findings will guide police investigators and, eventually, support the state attorney general’s legal position.

A crime scene investigator collaborates with police officers, detectives, and members of the judicial system to ensure that criminal offenders are held accountable for their actions.

Before turning the scene into usable evidence for law enforcement, a crime scene investigator must first preserve it by sealing it off to ensure that it is not contaminated or altered.
