Which of the following is considered a 'suspicious death'?

A 'suspicious death' typically refers to a death that is not easily explained and that may require further investigation to determine the cause. Homicide fits this definition, as it involves unlawful killing and can often be hidden under other circumstances, hence it demands thorough examination and inquiry.

In cases of homicide, there may be inconsistencies in the evidence, witness statements, or surrounding circumstances that raise questions about the nature of the death. This necessitates a forensic evaluation to ascertain whether foul play was involved, making it a focal point for further investigation.

On the other hand, natural causes generally indicate death from illness or age, which is typically well-documented and understood, thereby unlikely to raise suspicion. Accidental deaths, while they may involve some inquiry, are usually classified after any immediate investigations confirm their nature and do not usually incur suspicion about the cause. Historical death refers to deaths that have occurred in the past and, unless linked to unresolved crimes, do not generally invite current investigation of suspicious circumstances.
