Crime Scene Investigation Career Overview in Washington County
The field of forensic science in Washington County encompasses two primary career paths. Oregon crime scene investigators work directly at crime scenes, collecting physical evidence and documenting scenes through photography and detailed reports. Forensic scientists, also called criminalists, analyze this evidence in laboratory settings using advanced scientific techniques.
Washington County’s proximity to Portland creates a robust job market for forensic professionals. The Sheriff’s Office Forensic Science Unit processes evidence countywide and supports major-crime responses throughout Washington County’s 727 square miles.
Understanding what a CSI does helps prospective students recognize the dual nature of these careers. Some positions combine field work with laboratory analysis, while others specialize in one area. The technological advancement in forensic science continues to create new specializations and increase demand for qualified professionals.
