UNCONTROLLED COPY WHEN PRINTED MN BCA Forensic Science Service Evidence Submission Guidelines Authorized by: DAS Issue Date: 03/14/2013 Page 17 of 48 Pages Syringes without needles will be analyzed only if the submitting agency can demonstrate that the analysis is of major significance to the case and with the approval of Laboratory Management. Sealing, Marking and Submitting Controlled Substance Evidence: Mark and identify each container with: o Agency case number o Suspect o Date(s) of multiple buy(s) o Location where each piece of evidence was found Seal appropriately in a suitable container. (One Agency Case Per Container) Do not use a DWI kit for mailing drug evidence Do not mix drug types in one container unless found that way. Air dry wet samples (especially live marijuana plants) Package individual items of evidence separately and keep items for separate defendants packaged separately. Provide information concerning which defendant is associated with which item. Do not heat-seal into “compartments”. Take a representative sampling of liquids (30 milliliters/1ounce or less). Package in appropriate “clan lab” packs (glass vial with Teflon-lined cap stored in a Nalgene bottle) The charging level for khat is not weight dependent – submit one bundle. If the khat is fresh, keep it frozen. Latent Prints on Packaging – if latent print examination needs to be performed on the packaging, separate the drug items from the original packaging material (if possible). Please label suspected biohazards appropriately (body cavity samples, syringe contents).
