What is commonly the best evidence in cases of suspected suicide?

In cases of suspected suicide, physical evidence at the scene is often regarded as the best evidence because it provides tangible, direct information relevant to the circumstances surrounding the individual's death. This may include the presence of substances, weapons, or other tools that could indicate a method of suicide, as well as any environmental factors that might have influenced the situation.

Physical evidence can also include the positioning of the body, indications of previous mental health struggles, or any immediate signs of struggle that could suggest foul play rather than suicide. Such evidence allows investigators to form a complete understanding of the scene and assess all possibilities regarding the manner of death.

While witness testimonies, suicide notes, and autopsy results can also provide valuable insights, they are often subject to interpretation and can vary in reliability. For instance, witness accounts may be influenced by personal biases or incomplete information. Suicide notes can offer context but may not always paint a clear picture of the intent behind the act. Autopsy results are crucial for confirming the cause of death but may not address the broader circumstances surrounding the event. Consequently, physical evidence holds a primary place in establishing the facts in suspected suicide cases.
