Patterns of Witness Presence In Suicide Deaths across the Life Course

Background: Witnessed suicide accounts for approximately 4–15% of suicide deaths. Individuals who witness suicide often experience profound guilt, shame, anger, and intrusive/obsessive thoughts related to death. Despite these documented impacts, empirical studies examining suicide deaths that occur in the presence of others, whether as eyewitnesses or the person who found the decedent, are scarce.

Methods: This study systematically examined patterns of suicide deaths in which another individual was present at the time of the incident using de-identified medical examiner records. “Present at the time of the incident” was defined as any individual who was visually or audibly present during the decedent’s suicide attempt. Through a Memorandum of Understanding with a metropolitan county medical examiner’s office in a Southern U.S. state, the research team analyzed 361 de-identified suicide cases, which occurred between 2019 and September 2025. Decedents ranged in age from 9 to 92 years.

Data included demographic characteristics (e.g., age, race, sex, marital status, and occupation), contextual information (e.g., location of injury, time, and date of death), and narrative information from collateral reports and medical examiner remarks. Medical examiner narratives were systematically coded to capture events preceding death (e.g., relationship, financial, legal, and occupational stressors), suicide means, witness presence and relationship to the decedent (visual and auditory), toxicology findings and substance involvement, prior engagement with medical and mental health services, and reported barriers to care (e.g., insurance and access to treatment or medications). Examining these patterns is critical for informing suicide prevention and postvention efforts and for better understanding suicide deaths that occur in the presence of witnesses.

Results: Among decedents who died in the presence of others, 75% were White, 18% were Black, and 7% were from other racial groups. The majority were male (85%), with 15% female. Age was categorized into seven groups (0–14, 15–24, 25–34, 35–44, 45–54, 55–64, and 65+). Witnesses were classified as family members, current or former intimate partners, first responders or law enforcement, and bystanders (e.g., friends, neighbors, or roommates).

A Pearson’s chi-square test of independence indicated a statistically significant association between age group and witness type, χ²(18, N = 356) = 31.84, p = .02, with a small-to-moderate effect size (Cramér’s V = .17). Patterns of presence varied across the life course. Family members were most frequently present in suicides involving children under age 15. Among adolescents and young adults, the presence of intimate partners and bystanders increased. Intimate partners were the most common witnesses throughout midlife, while among older adults, intimate partners remained predominant, with family members also frequently present.

Implications: These findings underscore the need for trauma-informed postvention services that explicitly address the dual trauma of witnessing and losing someone to suicide. Given that these events overwhelmingly occur within close interpersonal relationships, immediate access to support for witnesses is essential. Prevention efforts should prioritize training for family members and intimate partners to recognize warning signs and intervene effectively during crises.
