As a crime investigator, one of the toughest questions I’m asked is how to process a crime scene. One of the most important steps in this extremely sensitive investigation is the cleanup of the scene. If not completed properly, it can cast doubt on the validity of the evidence and may affect the entire case. Therefore, it’s extremely important to understand how to appropriately and professionally clean up crime scenes.
Crime scene processing consists of collecting all evidence, which will be processed by law enforcement agencies. This includes processing blood, urine, and blood from the crime scene, processing tissue samples, and processing bite marks and hair samples. These particular aspects are handled by various state and local agencies, including the FBI, and the medical examiner’s office. As stated earlier, the handling of blood and bodily fluids is extremely delicate and requires a highly developed quality control program.
As stated above, the handling of any evidence is also a sensitive matter and can only be handled by professionals who have extensive training in doing just that. Therefore, it is imperative that the crime investigator has an established record of compliance when processing samples and conducting autopsies on individuals. This will ensure that the scientific data collected is accurate and free of contamination.
During the processing of materials, police officers are required to protect any potential sources of DNA evidence or physical evidence. This means that they must seal all crime scenes and storage containers and secure the area at all times. They should also secure the site by making sure that security measures such as closed circuit TV cameras are in place. In addition, they should conduct an inspection of the site to make sure that all employees, visitors, and any other people that might come in contact with the scene are protected.
As mentioned earlier, proper disposal of materials is one of the most important considerations when it comes to crime scene clean up. As such, it is critical that any materials left after cleansing are sent to the appropriate recycling company. In addition, police departments are required to keep the crime scene information about the crime and any additional materials they might collect on the scene. It is important to remember that these are the only resources available to police officials, and so they will make every effort to keep the information as current and up-to-date as possible.
After everything is cleaned up, it is time to think about how to process a crime scene. Some companies simply take the crime scene away in pieces. Other companies will process the scene and then send it to an environmental lab for testing. This includes chemical analysis, photosynthesis, DNA testing, and more. After the testing is complete, the company can determine the exact cause of the contamination, and work with the state agencies to make sure that justice is done.
However, some police departments prefer that the crime scene is cleaned up in its raw state. This means that police officers to clean up the crime scene before any testing is done. If this is the case, then there will be no testing done by an environmental agency. Instead, the cleaning up company will handle that work for them. When a company handles a crime scene, they will first inspect it to see if anything can be recycled. Next, they’ll take all the necessary precautions to protect the environmental agency from contamination.
If the company works out of a house or building, then they will clean the area inside the home or building and then go from room to empty the contents. If the crime scene covers an entire parking lot, then the team will take everything out. If a cleanup company needs to work indoors, they will have to do everything inside the building and then vacuum after they are done to ensure that it is safe for workers to come back into the facility.
