What term is used for a person confirmed to have died under suspicious circumstances?

The term used for a person confirmed to have died under suspicious circumstances is "victim." This designation typically implies that the individual is viewed as someone who has suffered harm or loss as a result of an event or situation, particularly in the context of a crime or suspicious activity. In forensic and legal contexts, referring to a deceased person as a victim conveys that their death is not considered natural and likely involves foul play or requires further investigation.

The other options, while related to the state of being deceased, do not adequately capture the nuance of the circumstances surrounding the death. Describing someone as a "dead person" or "deceased individual" lacks the implication of wrongful occurrence or outside involvement. The term "alleged victim" may suggest that the death is not yet confirmed as suspicious or that there are unanswered questions about the situation, which is not applicable when discussing someone confirmed to have died under suspicious circumstances.
