(a) All sampling procedures shall be carried out at the Division's evidence facility. A DCI Special Agent shall remain in control of the bulk seizure and shall ensure the proper documentation of the sampling process as well as the proper submittal of the bulk seizure and representative sample after completion of the sampling process.
(b) Entire seizures shall be photographed as well as videotaped. Duplicate prints/videos shall be made for the prosecution and the Division case agent. The negatives, if any, and one set of prints/video will be placed in non-drug evidence. Instant developing color cameras may be used only as a secondary means of documentation.
(c) A sign will be prepared containing the following: case number, amount of seizure (weight), and date of the seizure. The sign will appear in all photographs documenting the physical appearance of the bulk seizure. Additionally, a scale by which to measure the physical size of the seizure shall appear in at least 3 photographs, taken from different perspectives. Such scale may consist of a ruler, yard stick, or a person.
(d) The bulk seizure shall be unloaded, assembled or stacked in such a manner as to make clear visual display of the sampling technique. If the evidence is in closed containers, several containers shall be opened to display the contents.
(e) Only properly calibrated scales shall be used to weigh the entire bulk amount, as well as the representative samples. All weights and weighing procedures, including calibration of scales, shall be documented in the Division's case report.
(f) The agent shall, at all times during the sampling process, work in conjunction with designated crime lab personnel.
(g) After properly documenting the controlled substance bulk seizure, the agent, in conjunction with designated crime lab personnel, shall prepare a representative sample from the bulk amount of each type of controlled substance seized.
