The Evidence Control Unit (ECU) is responsible for receiving, logging, moving, tracking, and releasing all evidence for the Forensic Science Services Division. The unit is staffed by four Correctional Services Technicians.

All outside agencies submit evidence directly to ECU by appointment. Sheriff’s evidence is transferred to Forensic Science Services from the Property/Evidence Bureau.

Blood and urine samples are submitted by depositing the samples in locked refrigerators in the evidence receiving area. To gain access to the receiving area, use the access code or the telephone in the alley on the west side of the Brad Gates Forensic Science Building.

Blood and urine samples submitted for alcohol and other Toxicology tests are routinely analyzed without a formal work request.

Controlled substance and document cases may be submitted to ECU with an attached work request form without prior approval for analysis. Syringe cases require prior approval before submission. Syringes must be safely packaged in safety tubes.

Evidence intended for analysis by the
Identification Bureau or the Firearms, Trace, or DNA unit of the Criminalistics Bureau should not be submitted without prior notification. This is accomplished by submitting the work request to the appropriate supervisor for review (usually by FAX).
