As an evidence technician, your job is to use forensic techniques to investigate a crime scene and provide information for law enforcement agents. As part of this, you may conduct a computer analysis of debris and damage, collect DNA, test a sample of a product, and otherwise support efforts to track and stop further criminal activity. Evidence technicians are also responsible for receiving, storing, and disposing of evidence in line with local regulations. Most evidence technicians work for police departments or other law enforcement agencies, but you can also find work in private security or support positions. If you work outside of a police force, you may focus on handling evidence, creating a chain of custody document, and creating records of all evidence so it can be retrieved as needed.
