The "God's Banker" case exemplifies the thorough reconstruction of a crime scene's specifics long after the event to challenge the initial verdict of suicide. Driven by the family's unwavering belief that a homicide had taken place, the forensic unit had to meticulously piece together the incident and scrutinize all the evidence. Analysis of substances found on Calvi's shoes, which included a variety of particles like paint, rust, and metal, as well as the detection of a unique mark on his neck suggesting strangulation, challenged the original assumption of suicide and played a key role in ascertaining the banker's actual cause of death. The situation underscores the importance of unwavering resolve, meticulous examination, and the use of scientific techniques to challenge preliminary findings and doggedly seek precise information, even well after the criminal act has taken place.

Practical Tips

• Create a personal "mock trial" exercise where you take an event from your life or a hypothetical scenario and gather evidence as if you were preparing for a real court case. Document everything you would present, including photos, documents, and potential witness accounts. This will help you understand the rigor and detail required in collecting and presenting evidence that could stand up in a legal setting.
• Create a "What's Off?" game with a friend or family member. Take turns altering a shared space slightly by moving objects or changing something about your appearance. The other person has to identify what has changed. This playful activity can enhance your ability to spot discrepancies and small details that might otherwise go unnoticed.
• Improve your understanding of forensic evidence by taking a free online course or webinar on the basics of forensic science. This will give you a foundational knowledge of how experts analyze and interpret different types of evidence, such as stab wounds, which can be useful in a variety of real-world situations, from following news stories to serving on a jury.
• You can enhance your decision-making by creating a 'bias journal' where you note down decisions you make, the reasons behind them, and any biases you suspect might have influenced you. Over time, this will help you recognize patterns in your thinking and allow you to adjust for greater objectivity. For example, if you notice you often justify decisions based on anecdotal evidence, you might start seeking out more empirical data in the future.
• Improve your understanding of the scientific method by conducting simple experiments with household items. For example, you could test the effectiveness of different substances (like soap, vinegar, or baking soda) in removing stains from fabric. Document your hypothesis, the experiment process, and the results. This mirrors the experimental approach used in forensic science to draw conclusions based on evidence.
• You can enhance your critical thinking skills by analyzing controversial cases in the news. Start by selecting a high-profile case that has received different interpretations in the media. Research the facts from multiple sources, write down the differing viewpoints, and then use the evidence to form your own conclusion. This practice will help you develop the ability to assess information critically and make informed judgments, similar to re-evaluating a case like the "God's Banker."
• Create a "Resolution Buddy" system with a friend or colleague where you hold each other accountable for following through on commitments. Set a regular check-in schedule to discuss progress, setbacks, and strategies for maintaining resolve. This partnership can help maintain your determination and provide an external perspective to ensure thorough examination of your actions and decisions.
• You can enhance your observational skills by practicing detailed note-taking during routine activities. Start by observing a scene, like a park or a coffee shop, and jot down everything you notice, from the number of people present to their behaviors and interactions. This hones your attention to detail, a key aspect of gathering precise information, similar to techniques used in criminal investigations.

The challenges of preserving and examining forensic evidence become particularly acute in the context of unresolved historical cases.

Clarkson's book reveals the significant challenges faced by forensic scientists when it comes to preserving and analyzing evidence, particularly in cold cases where time has often degraded or even destroyed crucial clues. This section delves into the intricacies of handling delicate trace evidence and the impact of environmental factors on scrutinizing the sites where crimes have occurred.

Advancements in the realm of forensic science, especially in the area of DNA profiling, have enabled the solving of many cases that were unresolved for extended periods.

The author underscores the importance of the groundbreaking DNA profiling technique developed by Professor Alec Jeffreys. This groundbreaking technique revolutionized the resolution of criminal cases by providing a dependable means for identifying people, linking them to particular locations where crimes occurred, and exonerating the falsely accused. However, Clarkson emphasizes the challenges associated with investigating long-unsolved cases, particularly in the analysis and interpretation of degraded genetic evidence. Advancements in DNA technology have empowered forensic specialists to scrutinize even the tiniest specimens, enabling the amplification of minimal amounts of genetic material to yield actionable results.

The writer highlights the significance of genetic material as key evidence that solved enduring unsolved cases, such as the one involving "John Cooper," which involved two separate instances of double homicide that remained unsolved for almost two decades. In 2005, the case underwent another thorough examination, and thanks to the investigative team's consistent attention to detail and meticulous maintenance of evidence, advanced DNA profiling techniques were successfully employed. The incontrovertible link that resulted in Cooper receiving a life sentence was the discovery of Peter Dixon's genetic markers on shorts belonging to John Cooper, along with the detection of Dixon's blood on a weapon that Cooper used in a later robbery.

Clarkson emphasizes the crucial role of familial DNA testing in solving mysteries where the perpetrator's genetic material is not present in existing databases. By comparing DNA collected from the crime scene with the genetic profiles of family members stored in the database, detectives are able to narrow down their suspect list. This advanced technique signifies the progression from simple individual identification to the creation of intricate familial trees through DNA analysis, providing a powerful tool for deciphering the complexities of cases that have remained unresolved for an extended period.

Practical Tips

• Explore your ancestry by using a direct-to-consumer DNA testing kit to uncover your genetic heritage and potential health predispositions. These kits typically require a saliva sample that you send to a lab, and in a few weeks, you receive a detailed report about your ancestry, traits, and sometimes health risks based on your DNA profile. This can be a starting point for understanding your roots and taking proactive steps towards personalized healthcare.

Other Perspectives

• While DNA profiling has indeed solved many cases, it is not infallible and can sometimes lead to false positives if the DNA evidence is contaminated or if the statistical analysis is not handled correctly.
• In some instances, the re-examination of long-unsolved cases with fresh eyes and new perspectives can lead to insights that were previously overlooked, which may reduce the reliance on degraded genetic evidence.
• Amplifying minimal genetic material does not address the issue of degraded DNA, which can be too damaged or fragmented to provide reliable results, even with advanced technology.
• The success in the Cooper case might also be attributed to advancements in DNA technology rather than solely the thoroughness of the examination and evidence maintenance.
• Familial DNA searching can lead to ethical dilemmas, as it may reveal sensitive information about family relationships, such as non-paternity or undisclosed adoptions, which can have profound personal impacts.
• The technique may disproportionately affect minority communities if they are overrepresented in DNA databases due to systemic issues in the criminal justice system.
