What is decomp stain?

Decomp stain, also known as decomposition stain, is a discoloration or staining that occurs during the process of the decomposition of organic matter. It is caused by the breakdown of cellular material, the release of enzymes, and the production of gases and fluids such as blood and bodily fluids.

These stains can vary in appearance, from brown or yellowish hues to deep red or black depending on the type, age, and amount of organic matter present. They can also have a distinct odor that is often described as putrid or unpleasant.

Forensic investigators use decomp stains to help determine the time and cause of death, as well as any other pertinent information related to a crime scene. The analysis of these stains can provide important clues as to how long a body may have been in a particular location, the position and manner of death, and the presence of any significant injuries or traumas.

Decomp stains can be difficult to remove and may require specialized cleaning products and techniques to effectively eliminate them. Proper handling of contaminated materials is also important to prevent the spread of pathogens or other harmful substances.
