Forensic Investigation Section (FIS)
The Forensic Investigations Section is a vital component of the Forensic Science Division. We provide professional crime scene investigation, scientific analysis, and evidence preservation to support multiple agencies throughout northern Nevada. Crime scene analysis involves meticulous documentation through notes, photography, diagrams, the recovery of impression evidence, and the collection and preservation of physical evidence. We utilize state-of-the-art equipment to detect and preserve various forms of evidence, supporting investigations into a wide range of complex crimes.
Our team operates 24/7, 365 days a year, ensuring a timely and coordinated response.
Crime Scene Types Processed
The various complex crime scenes include, but are not limited to:
- Homicide
- Attempted homicide
- Officer-involved shootings

Any requests for scene processing for crime types not listed above must be directed to the FIS Supervisor or Division Director. Also, requests for services outside the Washoe County area must be directed to the FIS Supervisor or Division Director.
Crime Scene Activities
When FIS analysts respond to a scene, they evaluate the crime scene, evidence, and information provided to determine the most suitable processing methods and take the necessary actions.
To collect possible impression evidence, our analysts use powders, electrostatic, ALS (Alternate Light Source), casting material, and photography to document and collect shoe/tire impressions and latent, patent, and plastic prints.
Latent prints recovered from scene processing will require the agency to submit a testing request for latent comparison.
Should a vehicle require processing, FIS has on-site garage bays that accommodate large vehicles for processing.
Automatic Processes Performed
Any case-related photographs taken by FIS related to scene processing will be automatically provided to agencies.
Homicide and officer-involved shooting crime scenes will automatically have 3D diagrams generated for the lead agency.
