Every file is written from cited sources and pinned where it happened, and every person named carries the legal status the record gives them. If you hold information about an unsolved case, contact the investigating agency named in its file rather than posting it publicly. Families and anyone involved can request a correction from any file.
This page updates from the published files, so counts and statuses change the day a record does. Open any file for its timeline, its sources and the coverage worth your time, or play it as a narrated case file.
