Which type of record can provide demographic information relevant to death investigations?

Psychiatric records can indeed provide essential demographic information relevant to death investigations. These records typically include personal details such as the individual's age, gender, and possibly their family history or living situation. In the context of a death investigation, understanding the mental health background of the deceased can be critical, especially if there are factors that may contribute to the cause of death, such as mental illness or substance abuse issues.

While family photos, financial records, and social media accounts may contain some demographic information, they are generally not as systematically organized or comprehensive in documenting personal data as psychiatric records are. Family photos may reveal relationships or details about social circles, but they don't offer the structured information found in medical documentation. Financial records can indicate socioeconomic status but are limited in capturing personal details relevant to the individual’s life history as it pertains to the circumstances surrounding a death. Social media accounts can provide insight into a person's connections and activity but lack the detailed demographic data essential for thorough death investigations.
