What must be confirmed in a suicide investigation?

In a suicide investigation, it is essential to have the conclusion affirmed by the best available evidence. This means that the determination of suicide must be supported by concrete and reliable proof, such as physical evidence, the circumstances surrounding the death, and thorough documentation of the scene. This emphasis on best available evidence ensures that the conclusion reached is not based solely on assumptions or inadequate information but rather is backed by factual and objective support.

Identifying a motive, while potentially valuable for understanding the context of the individual's circumstances, is not a definitive requirement to confirm a suicide. Similarly, while determining if any witnesses were present can contribute to the investigation, the presence of witnesses alone does not substantiate the ruling of suicide. Additionally, while understanding the victim's mental state is important, it does not serve as the primary foundation for confirming a suicide unless supported by further evidence. Thus, the emphasis on affirmation through the best available evidence is crucial in establishing the nature of the death appropriately and responsibly.
