Step-by-step explanation:
Trashing refers to the act of discarding or disposing of something, usually in a careless or haphazard manner. In the context of an investigation, trashing can refer to the physical act of discarding or destroying evidence, or it can refer to the electronic form of trashing, which involves deleting or tampering with digital information.
In an investigation, trashing can help by providing clues or evidence that can be used to support or refute a theory or hypothesis. For example, if a suspect discards a weapon in a trash bin, it can be recovered and used as evidence. In the electronic form, trashing can help investigators recover deleted files or uncover digital footprints that can be used to track a suspect's activities.
