The forensic investigation process involves gathering evidence. There are several steps involved, which include: Identifying potential sources of evidence, Documentation, and Criminal Profiling. The forensic investigator duplicates forensic data and verifies its integrity. For this process, the examiners assume that law enforcement obtained the original data and that they have a forensic image (a bit-for-bit copy of the original data). Examiners must protect the chain of custody of original evidence.
Identifying potential sources of evidence
One of the most important phases in a forensic investigation is identifying potential sources of evidence. These may include physical devices, network data, and digital information. Digital evidence is often in a disorganized format, making it difficult to process and identify. In addition, not all data can be interpreted by humans. Hard drive platters, for example, contain pieces of information that are not always organized and layered over time. Only a small fraction of these pieces of information will be relevant to the case. Therefore, it is critical to identify all potential sources of evidence before attempting to use them.
The next step in identifying potential sources of evidence is to review the data that are available. The data that are available can include traces from the crime scene. These traces can be used to determine the type of crime.
Identifying digital footprints
Identifying digital footprints is an important step in a criminal investigation. Digital footprints are the traces left behind by people when they use technology, such as websites visited, time spent online, and devices used. When used correctly, digital footprints can help investigators get crucial evidence and information. For example, the case of Krenar Lusha and Matt Baker was solved with the help of digital forensics. However, police are still struggling to keep up with the ever-growing backlog of digital evidence.
The process of identifying digital footprints during a forensic investigation can be a lengthy one, and it may take several iterations before a client or court can approve the findings. Throughout the investigation, each step is carefully documented to ensure the validity of the results. At the end of the process, a detailed report detailing the findings is generated. This document should comply with the standards set by the court and the client.
Identifying criminal profiling
The process of identifying criminal profiling can provide investigators with investigative strategies and leads. However, more research is needed to fully understand how this method can be used to solve a case. Profiling refers to the grouping of offender behaviors based on common psychological characteristics. It can also be used to reduce the number of viable suspects in a case. It can be done by looking at crime scene indicators and behavior patterns, as well as assessing whether there is an increased risk of nuisance criminal behavior.
Although the practice of criminal profiling has been around for many years, it was only in the 1970s that it became a formalized process. In the 1880s, doctors in Britain started to draw inferences from the behavior of the infamous Jack the Ripper. However, it wasn’t until 1972 that the FBI’s Behavioral Science Unit began investigating the growing tide of homicides and serial rapes across the US. This unit developed databases and advanced techniques that led to the arrest of serial killers such as Ted Bundy.
Documentation during the forensic investigation process is an essential step for any crime scene investigation. During the investigation process, investigators must take careful measures to secure the scene, document the evidence, and document the time and date of the crime. Documentation of the crime scene is essential for establishing the continuity of the evidence and proving its authenticity.
Investigators must also take careful notes. Documentation should be comprehensive and should capture the investigator’s perception of the incident. The investigator may recall some facts later, but it is best to write them down as soon as possible.
The process of forensic investigation requires identifying and collecting evidence and conducting a number of analyses. The results of each stage of the investigation must be interpreted and documented to provide the most accurate conclusion possible. The prosecutor and the forensic examiner must agree on the extent of the analysis to be performed at each stage. The process may be iterative, in which the same data sources are gathered and analysed more than once. The investigators should communicate the results of their work to the parties involved in the investigation.
