How Criminals Get Caught: The Role of Forensic Evidence and Advanced Investigations

Crimes are often portrayed in media as perfectly executed with no trace of evidence left behind. However, the reality is quite different. According to the Transfer of Evidence Theory, there are almost always traces or indicia. It is the detection and collection of these valuable clues that can pose a challenge at times—especially with the advancement of technology bridging these gaps.

The Power of DNA in Solving Crime

One of the most powerful tools that law enforcement can use to solve crimes is DNA. The belief that a crime can be committed without leaving any evidence is inaccurate; a person who commits a crime will inevitably leave something behind. Factors such as the pressure of the situation, the time factor, and the need to get away typically result in some form of evidence being left behind—be it a tool, a bullet, sweat, a hair, or a cigarette butt.

Every Crime Scene Has Clues

Even in the most sterile environments, evidence can still be found. Imagine walking into a surgical room that has become a crime scene: where do you start, and what do you consider? The first piece of information to gather might be the surgical tools. Which companies made them? What type of company are those aligned with? Business history often reveals vital information, as companies, like babies, grow and change over time.

Environmental Indicators

Consider the smells, chemical use, and the overall environment:

Smells: What odors are present? The smell of disinfectants, chemicals for cleaning instruments, and even air conditioning. These can provide clues. Chemicals: What cleaning agents were used on floors, ceilings, or surgical scrubs? The types of chemicals can reveal valuable information. Atmosphere: What kind of air treatment systems are present? Consider if there is a dry ice machine or an autoclave.

Donors or equipment sources might also offer valuable insights. The amount and type of resources devoted to operating on different ethnic groups or categories of people can be significant. This can be an indicator of the financial and resource allocation, providing further context.

Smaller Details and Their Impact

Even seemingly insignificant details can be revealing. For example:

Medical Supplies: The use of morphine or anesthetics can be noted, and where these were in the room. If the medicine has moved or is missing, it can raise suspicion. Operative Process: If an operative proceeded and the patient collapsed, where did it occur? The location can suggest multiple scenes, leading to a search for a non-sterile environment. Fluids: Where did the fluids go? The absence or disappearance of fluids could lead investigators to a dumping or burial ground. Hospital Facilities: Check if there is a high-temperature crematorium within the hospital. Such facilities might be connected to services that handle deceased bodies, such as embalmers or body cleaners.

Post-Mortem Examinations

Medical examinations or autopsies might reveal hints of evidence:

No Visible Evidence: Sometimes, there is no clear visible evidence of fluids or chemicals used in the process. This can happen with drugs that are administered to stop or assist organs to shut down. Timing: Autopsies are usually performed as soon as possible. However, in cases where there is a lack of Clinicotypical evidence, the process may have to wait until the body starts to decompose, allowing time for filtration and the detection of illegal substances. Odors and Injuries: Look for any odors, particularly those related to decomposition. Examine for any visible bruising or evidence of internal burns, vein hemorrhaging, or fracture patterns suggesting deliberate action.

Overall, the combination of advanced forensic techniques, meticulous investigation, and an open mind can help reveal the hidden evidence that leads to the apprehension of even the most cunning criminals. While it may not be straightforward, the presence of forensic evidence ensures that the ‘perfect crime’ remains just a fictional concept.
