Personnel in the Evidence Receiving are responsible for taking in, processing, securing and maintaining the chain of custody for criminal evidence in cases submitted by law enforcement personnel.
Because evidence may be examined by different sections under the control of the laboratory system, staff involved in the process must conform to strict protocols and policies.
All evidence movement is documented via the chain of custody section in LIMS.
