Answer & Explanation:
Overlapping stains at a crime scene can provide several details to investigators, including the sequence of events and the position and movement of the people or objects involved in the crime. For example, if bloodstains from two different individuals overlap, it suggests that the two individuals were in the same location at the same time and that some type of interaction took place between them. The shape and size of the overlapping stains can also provide information about the angle and direction of the impact or force that caused the stains. Additionally, the DNA analysis of the stains can help to identify the individuals involved in the crime. Overall, overlapping stains can provide important clues to investigators and help them to reconstruct the events that occurred at the crime scene.
