Estates later sued OpenAI and Microsoft, alleging ChatGPT/GPT-4o validated paranoid delusions; OpenAI disputes causation.","full_description":"Police described a murder-suicide at the home the two shared. Complaints allege months of GPT-4o chats reinforced conspiracy beliefs and recast Adams as a threat. OpenAI has denied responsibility. Public reporting notes that available chats have not shown explicit instructions to kill. This ledger records the deaths and chatbot use as documented, and legal causation as disputed—the same pattern as the Character.AI Setzer entry.","ledger_type":"harm","primary_domain_id":"c09546b6-10f8-48df-8347-0c1979416464","event_status":"disputed","event_date":"2025-08-05T00:00:00.000Z","discovery_date":"2025-08-05T00:00:00.000Z","first_published_date":"2025-08-05T00:00:00.000Z","last_reviewed_date":"2025-08-05T00:00:00.000Z","geographic_scope":"Greenwich, Connecticut, United States","affected_population":"Suzanne Adams, Stein-Erik Soelberg, and their families","base_impact_tier":3,"base_score":"10.00","attribution_multiplier":"0.3500","evidence_multiplier":"0.5000","realization_multiplier":"1.0000","durability_multiplier":"1.0000","current_event_score":"1.225000","confidence_level":"medium","score_explanation":"Two documented deaths associated with extended chatbot use are major individual harm (tier 3).
