Police on a scene of a homicide have to deal with the dirty details of investigating the scene scene and determining what needs to be done to ensure that the victim's killer is brought to justice. However, when the coroner leaves the property with the body and the tape from the scene is removed, it is no longer their job to deal with the aftermath cleanup of the home. The crime scene cleaners are who deal with homicide cleanup, these are usually independent remediation companies that are specially trained in blood cleanup and have an understanding and knowledge in how to deal with blood waste and material which is what the remains of the body are.
The cleaners, have advanced training in how to safely handling cleaning blood and body fluids from the property. They will pickup all of the material left over from the homicide and then provide solutions to effected areas such as sanitization and decomposition of the homicide scene as well as the removal of any walls, floor boards, carpeting, and other furniture in the home that is effected from this. As crime scene clean up goes, the job is not done until the home is considered to be completely safe for people to return and live in the house again.
