Crime scene clean up is a major job for any professional. This is especially true if the death or injury happened in a busy metropolitan area like Los Angeles. After the trauma, it can take weeks or even months to properly remove and recycle everything. Here are some of the best practices to follow when processing a scene.
There are several different types of crime scenes to process. First there is the police evidence. This refers to the evidence left behind by the police after a person has been fatally injured or killed. A police investigation is the main component of the forensic science process and this consists of collecting and preserving evidence such as blood, shell casing, bullet fragments, weapon residue, and other materials that can help establish the identity and criminal history of a person involved in the crime.
Next there is the medical evidence. This includes everything from death certificates and autopsies to medication and remnants of body tissue. If police can establish the cause of death, they can use this information to positively identify the deceased. As a result, these pieces of medical evidence should be properly disposed of.
Once all of the police evidence has been processed, the next step in the process is the examination of the scene itself. This portion of the process requires the assistance of special equipment and tools. It also involves interviewing a large number of individuals who were directly or indirectly involved in the crime, as well as collecting any potential DNA samples.
Some people wonder how to process a crime scene when there are dead bodies in the way. The reality is that it’s simply a matter of clearing away any trash and debris before the investigation can begin. There is no need to rush through this part of the process. In fact, police should let the scene stays untouched until all of the physical evidence is collected. After all, even if a body is not found on the scene, it could still be extracted during an investigation.
Once the police investigation is complete, they will review the processing procedures and make any necessary changes. Police reports typically include photographs and possibly video. These photos and videos will provide police with a clearer picture of the crime scene and the manner in which it was committed. If additional resources were required to process the scene, the investigating officer will make a notation in the report explaining the steps that were taken and the conclusion of the processing.
Many questions remain about how to process a crime scene. However, the overwhelming majority of questions have to do with the proper storage of evidence and the handling of physical evidence. While police officers are well-trained not to touch physical evidence, it is up to the individual to store it securely so that it can be evaluated later. Proper storage is absolutely essential. Crime scene investigators are very well-trained in this area and there are storage facilities and companies who specifically serve this field.
The steps involved in processing a crime scene differ slightly from those involved in processing a death scene. Since a death scene is usually a record of how the deceased person died, there are few steps involved in processing a death scene. In a death scene, however, all physical evidence is important such as bullets or other projectiles that might be important indicators of a firearm, and the path of the bullet or other projectiles could be crucial information to determine the manner in which the deceased died. In a death scene, the processing is done based on the evidence that is available. The same cannot be said for processing a crime scene.
