The forensic science technician collects, identifies, classifies and analyzes physical evidence for criminal investigations. Technicians also collect such evidence as hair, DNA samples, fiber, blood and tissue at the crime scene
They may testify in court for a criminal investigation or trial, which could include expert witness testimony, explaining evidence collection, or explaining test processes used in analyzing evidence such as fingerprints, DNA, fiber, or bullets. It is possible that a forensic science technician specializes in one area of analysis or investigation, such as firearms or DNA analysis. Conferring with other departments and organizations, such as police and attorneys, must be done during the investigation and during trial.
Most of the job requires sitting in a lab in sterile or near-sterile conditions, using various scientific equipment alongside others doing the same or similar work. Most of the work is done during the week on a regular daytime shift, but the forensic science technician may also be required to be on call 24 hours.
Forensic science technicians must have impeccable record-keeping and developed analysis skills, since forensic evidence can be thrown out if records and/or data are flawed. Critical thinking and strong problem-solving skills are important, as is knowledge of relevant computer programs. Good communication skills are required to be able to testify or confer with other people and departments involved in evidence collecting, analysis and investigation. No degree is required, but some states require a license as a private investigator.
