👉 Murder fluid, also known as "bloody glove" or "sawdust fluid," is a substance used by some serial killers to conceal the bloodstains left on their victims. This fluid is typically a mixture of saliva, blood, and other bodily fluids, often mixed with substances like sawdust or other fine particles to create a powder-like consistency that adheres well to surfaces, particularly porous materials like fabric or wood. The purpose is to make the blood appear as if it had been shed from a different part of the body, thereby concealing the crime scene and making the murder appear less obvious. This technique is particularly effective in cold cases where physical evidence might otherwise be overlooked.
