Advanced forensic and analytical methodologies are essential for preserving and interpreting evidence such as crime scene preservation and documentation, DNA and trace evidence analysis, and forensic pathology. Crime scene preservation is when investigators preserve the crime scene by securing the area. They take photographs and write logs. DNA and trace evidence analysis is direct evidence like blood, hair, or fibers. For example, collection of these involves tweezers or swabs. Lastly, forensic pathology is determining the cause and manner of death. Autopsies reveal the time of death, injuries, and any wounds. The interplay of physical evidence environmental factors, and witness accounts are depended on throughout an investigation. The physical evidence can paint a clearer picture of what occurs before, during, and after the crime. Challenges with biases can sway the directory of an investigation. Investigator biases derive from theories that the investigator may have about the case. Contamination of evidence if not properly secured can compromise any critical piece of evidence. Overlooked evidence can leave out critical pieces and change the narrative of the investigation. One case study is the Golden State Killer where some techniques led to a breakthrough. “The forensic investigative process and various investigative DNA tools will also be described. The Golden State Killer Case (1) will be examined to highlight and discuss forensic ethical issues to develop an ethical framework, as well as provide recommended solutions to pressing public safety and privacy issues facing crime laboratories and criminal investigators. Use of the ethical concept of proportionality (2) will be utilized to contrast and balance competing ethical concerns” (Wickenheiser, 2019). On the other hand, in West Memphis, three case lapses underdetermined the case.
