Forensic science technicians reconstruct crime scenes by carefully studying information gathered by investigators and conducting scientific tests on physical evidence. For example, lab technicians may look at photographs of blood splatter patterns and conduct ballistics tests on bullets found at the crime scene to determine the direction from which a shot was fired.
Forensic science technicians who work in laboratories use chemicals and laboratory equipment such as microscopes when analyzing evidence. They also use computer databases to examine fingerprints, DNA, and other evidence collected at crime scenes in order to match them to people and things that have already been identified. Most forensic science technicians who perform laboratory analysis specialize in a specific type of evidence analysis, such as DNA or ballistics.
All forensic science technicians prepare written reports that detail their findings and investigative methods. They must be able to explain their reports to lawyers, detectives, and other law enforcement officials. In addition, they may be called to testify in court about their findings and methods.
Forensic science technicians must travel to different locations around a city or region because crimes can occur anywhere. Crime scene investigation can be distressing and unpleasant because investigators see many disturbing sights. Crime scene investigators work staggered day, evening, or night shifts and may have to work overtime because they must always be available to collect evidence.
