Processing Physical and Digital Crime Scenes
Processing the physical and digital crime scenes are the essential processes that determine the success of the investigators in their bid to solve crimes. Knowing the methodical processes to take to document and process these scenes is therefore essential for successful solution of such crimes.
Physical Crime Scene
The first step in processing a physical crime scene is the identification of the scene dimensions. This helps in establishing the perimeter that is large enough to have all the potential evidence that would be needed and also identifying the focal point of crime. The second step then consists of securing the crime scene itself. This security involves taping round the perimeter to prevent any potential tampering with the evidence especially when the scene is to be processed for more than a day (Kennao et al. 2019). This security also involves considering the use of security guards when the population is higher. The next step is then to create a plan and communicate. This involves determining the type of crime, threats to evidence and any additional resources needed. After this, primary survey is to be done whereby potential evidence is identified, photographs taken and notes also written down.
The documentation and processing of the scene is then done. It entails ensuring that no evidence is tampered with and that the evidence collected is detailed enough to help solve the crime. A secondary survey is then done as a walkthrough just to make sure that all that was to be documented is well documented and recorded. The final step is the recording and preservation of evidence in an inventory and thorough descriptions that match the records kept (Kennao et al. 2019).
Electronic Crime Scene
Processing this scene also begins with securing the crime scene. This is so that the electronic evidence is not tampered with and that they can be kept for use in the prosecution of the case. The next stage is the collection of the evidence. This involves the seizing of the hardware that is suspected to have been at the core of the digital crime. This process entails identifying any other potential devices that are connected to the device in question and collecting all for forensic analysis. After collection, it is important to secure the devices (Maneli, 2018). Unlike physical crime scenes, electronic gadgets can still be interfered with even while they are in custody remotely. The investigators have to ensure that they are secure. Next is the transportation of the evidence. During transportation, care is also taken to ensure that this does not change the evidence. The examination of digital evidence ought only to be done by people who are specifically trained to forensically look at them. Finally, all the digital gadgets that are collected for review have to be clearly documented to ensure that they are all available when the review is due.
In conclusion, investigators have to apply methodical ways of processing physical and digital crime scenes in order for the crimes to be solved. Securing, collecting, documenting, storing and reviewing these evidences from crime scenes then have to be done in an orderly fashion.
