What you can hold us to.
Victim-first language always.
We lead with respect and humanity. Victims are never reduced to headlines.
No sensationalism.
We do not chase clicks or shock. We prioritize clarity over drama.
No graphic content.
We never publish disturbing images or unnecessary details.
No guessing. No rumors.
We do not speculate. We do not amplify. We wait for facts and verify them.
Just sourced information.
Every case is built on credible records, official documents, and responsible reporting.
Trust is earned. We earn it by putting accuracy, context and compassion at the centre of everything we do.
How a case file is made.
It has to be on the record.
A case earns a place only if it is documented in public reporting or records. The catalog focuses on the United States, the United Kingdom, Canada and Australia, plus globally notorious historical cases. Ongoing trials and very recent cases are held to a higher bar or deferred.
Written from sources we already hold.
A first draft is written only from source text we have retrieved: published journalism, court and government records, and encyclopedic sources. Videos and podcasts are coverage we point you to, not what we cite facts from.
Two citations, at least.
No case file publishes with fewer than two independent citations, and every one is listed on the case page. Automated checks require valid citation URLs from independent hosts, valid dates, permitted language, and supported legal-status labels for named people.
Gated before it appears.
Files are written as drafts, then move through a review queue before anything goes live. Only files marked published are ever visible. If a file is later flagged or pulled, it leaves public view straight away.
Corrected in the open.
Each file shows the date it was last verified against its sources. When facts change, the file is rewritten from updated sources and marked with the date, and every correction goes into the public log.
Labels come from the record, never from prose.
Each case carries one status. It is a field in our database, set from the sources, and the chip you see is drawn from that field.
- UNSOLVED
- COLD
- ONGOING
- SOLVED
- OVERTURNED
Every named person carries a legal role tied to a citation. If the pipeline cannot tie a named person to both a citation and a legal status, it removes that person from the draft.
- VICTIM
- CONVICTED
- CHARGED
- CHARGES DISMISSED / WITHDRAWN
- PERSON OF INTEREST · NOT CHARGED
- ACQUITTED
- EXONERATED
- LAW ENFORCEMENT
Binding product rules.
Casepin is an educational archive of documented cases and the coverage that already tells them. These six rules bind every page, every narration and every video we make.
Victims are people first.
Every case file is framed around what happened to a person, not around the person who did it. Perpetrator nicknames and mythology never lead a page; they exist only so the case can be found by the names the public knows.
We use neutral verbs, we do not decorate tragedy, and nothing here can be liked or favorited. You can follow a case for updates; that is deliberate language.
No guilt we don't have.
The database stores each person's legal status. A cited person may appear as a victim, someone convicted or charged, someone whose charges were dismissed or withdrawn, someone acquitted or exonerated, or a law-enforcement official.
We name an uncharged person of interest only when law enforcement has named them in public. The label identifies the agency and says the person was not charged. Cases use "the murder of" only after adjudication; other titles use "killing," "death," or "disappearance."
Sources, not speculation.
Case files are written from published journalism, court and government records, and encyclopedic sources, and every file lists them. Videos and podcasts are coverage we point you to; they are not what we cite for facts.
A case does not publish with fewer than two citations. AI drafts are grounded only in retrieved source text, never model memory. Where our text draws on Wikipedia, we attribute it and share our case-file prose back under the same CC BY-SA license.
How we use AI, in the open.
We use AI, and we say so here rather than tagging every post. Language models write a first draft of each case file from sources we have already retrieved, and they help match existing coverage to the right case. On Casepin, a synthetic voice can read the already-published dossier text aloud; it is not a new source or a separately generated factual account.
Synthetic voices also narrate our short- and long-form videos. Atmospheric illustrative stills may pad a case's real archival records, and software helps assemble and edit those videos. What AI never does: it invents facts or quotes, decides what goes live, or generates imagery of a real victim, perpetrator, or crime scene.
Each case file uses its listed sources and must clear the publication checks described here. The human review desk handles holds and high-risk cases. Owner-authorized batches must pass the same machine floor at publication time, and failures remain held. We use a platform's machine-readable AI flag only where that platform requires it. This page is the canonical plain-language disclosure.
Corrections are a feature.
If something here is wrong, tell us and we will look at it, with first response within 72 hours. Requests from victims' families are handled first, and we will consider de-emphasizing accurate content when a family asks.
Every correction is logged. When facts change, the case file is rewritten from updated sources and marked with the date.
What we will not build.
No comment threads on real people's worst days. No play-detective mechanics, no tip collection, no gore, no crime-scene imagery, and no notifications engineered for dread. If you know something, contact the investigating agency on the case page.
