Biological evidence, controlled dangerous substance (CDS)

  Create a scenario that describes a crime in which there is at least one of each type of biological evidence, controlled dangerous substance (CDS) evidence, and questioned document evidence to be collected. Also include at least one type of evidence from CCJS 301 (trace evidence, impression evidence, or firearms or toolmarks evidence). Assume that you are responsible for collecting this evidence from your scenario. Discuss the difficulties that you may encounter during the collection of the scenario evidence and ways in which following the scientific method helps to diminish these ethical concerns. Explain the documentation necessary to present the scenario evidence with integrity in court.
