Foul play in death refers to criminal or violent activity that causes somebodys death. It is often used to describe a situation where the police suspect that a persons death was caused by someone elses actions, such as murder or manslaughter. Foul play can also refer to any dishonest, unfair, or illegal action, especially one that happens during a sports game. When someone is labeled "dead, with no foul play suspected," it means that the police do not suspect that the persons death was caused by criminal or violent activity. However, it is important to note that this does not necessarily mean that the death was natural or accidental. In some cases, further investigation may be needed to determine the cause of death.
