What jurisdiction does a coroner have over deceased persons?

The coroner's jurisdiction primarily extends to deceased individuals whose deaths are sudden or occur under suspicious circumstances. This is because the coroner is responsible for investigating the cause and manner of death in such cases to determine whether any further legal action is needed or if foul play may be involved.

This role is crucial for public safety and accountability, helping to clarify situations that might otherwise lead to uncertainty regarding the cause of death. The coroner collects evidence and may conduct autopsies to gather essential information to inform investigations.

In contrast, the other options would imply a broader or different scope than what coroners typically cover. Coroners do not investigate every single case of death (such as all deceased persons without exception or those who died naturally), nor do they focus solely on deaths occurring in healthcare facilities. Their role is specifically tied to circumstances that warrant a closer look due to the potential of unnatural causes or legal implications, making option D the accurate reflection of their jurisdiction.
