The forensic industry continues to evolve as science and technology advances. With these advancements comes a higher demand for specialized staff. Crime Scene Investigators, commonly referred to as CSIs, are forensic evidence technicians who are specifically trained in the detection, collection, processing, and preservation of forensic evidence recovered in connection with and/or at crimescenes. CSI Units are the “front line” in the forensic industry.

A CSI Unit is responsible for, but not limited to, the following tasks:

• Detection, preservation, processing, and collection of physical and scientific evidence recovered at crime scenes
• Expert courtroom testimony
• Latent print examination
• Detailed crime scene drawings for courtroom presentations
• Vehicle examination

To accomplish these responsibilities, the CSI Unit needs certain spaces within a forensic facility. They must be armed with an impressive array of technology and equipment to effectively do their job. Most law enforcement agencies do not have an adequate facility and are in desperate need of new equipment to support a CSI Unit.

What are the facility requirements to support a 15 to 20 person CSI Unit? The NIJ Blue Book has a wide range of suggestions to answer this question, but what does it really take for a CSI Unit to efficiently complete day to day activities? Experience teaches that the design and construction of forensic facilities that support a CSI Unit have the spaces and components outlined on the next pages.
