About LAST KNOWN
For people who want to examine the case, not just hear the story
LAST KNOWN is a provenance-first research environment for serious true-crime sleuths and researchers examining real unresolved homicide cases through structured claims, chronology, sources, documents, people, places, gaps, and corrections, with statements and conflicts shown where those records have been separately published. It is not law enforcement and it does not decide who is guilty.
Who the archive is built for
LAST KNOWN is designed for the person who checks the timeline, opens the original source, compares accounts, tracks what changed, and wants to know exactly what supports a claim before accepting it.
Why the archive exists
Important case details are often scattered across agency releases, records, interviews, reporting, documents, and later corrections. LAST KNOWN makes those details examinable without flattening different source types or competing accounts into one authoritative-sounding story.
What makes a LAST KNOWN record different
Material claims are kept atomic and connected to their provenance. Where the public record supports it, a researcher can inspect source version, exact excerpt or locator, chronology relationship, factual state, publication revision, and published correction history.
Uncertainty is part of the record
Official statements, witness accounts, reporting, allegations, disputed information, and unknowns are not silently merged. Conflicts stay visible when published. Approximate times stay approximate. Missing information is not filled with speculation.
Real people come before engagement
LAST KNOWN does not use suspect voting, guilt scores, leaderboards, unrestricted accusations, private-person contact campaigns, or entertainment mechanics. Actionable case information belongs with the verified official authority identified for the case.
Public record and private research tools
The public case record is not secret premium evidence. LAST KNOWN+ currently adds Source Lineage and the Private Research Workbench for source tracing, persistent private notes, and saved published claims. Planned capabilities remain roadmap items and are not treated as part of today's paid entitlement until they actually ship.
