Fact, not folklore: how we verify a case

Every old case carries two histories at once. There is what the record can show — what was charged, testified, ruled, and reported at the time — and there is what the years have added on top: the retold version, the neighbourhood legend, the detail that sounds too neat to be true and usually is. Our work begins where those two histories part company. Before a case becomes a walk, someone has to sit with the material and decide, line by line, which of it we are actually willing to say aloud.

Where research ends and checking begins

Research gathers the sources. The fact-check interrogates them. These are different jobs, and we keep them separate on purpose. A well-read draft can still be wrong — a date carried over from a secondary account, a name spelled the way a later writer preferred, a sequence of events tidied into a cleaner shape than the evidence supports. The checking step exists to catch exactly those quiet errors, the ones that survive precisely because they sound reasonable.

So nothing is taken on trust because it appeared in a draft. Each claim is read back against the documents it rests on, and a claim without a source it can point to does not stay in.

How we weigh a source

Not every source carries the same weight, and pretending otherwise is how folklore slips in. We rank what we read, roughly, in this order:

• Primary records — sworn testimony, charges, verdicts, inquest findings, and the documents produced at the time by the people involved.
• Contemporary reporting — the columns filed while events were still unfolding, valuable but written under deadline and worth reading against the record rather than as the record.
• Published histories and reference works — useful for context and for connecting threads, strongest when they cite their own sources.
• Everything else — the anecdote, the tour-guide flourish, the detail no document supports. Interesting, sometimes. Evidence, no.

When accounts disagree, and in older cases they very often do, we do not quietly pick the most dramatic one. We note the disagreement, say what is settled and what is contested, and let the listener hold both.

Fact, rumour, and theory

A great deal of what attaches itself to a famous case is neither true nor quite false — it is unproven. We treat those three categories as genuinely different things. A fact is something the record supports. A theory is an interpretation offered by someone, and it is presented as exactly that, attributed and clearly marked. Rumour that never entered any record does not appear at all, no matter how often it has been repeated. The measure is never how good the story is. It is whether we can stand behind it.

Naming the gaps

The record is incomplete more often than not. Documents are lost, a question is never answered, a motive stays unknown. The honest response is to say so. When the narration reaches a gap, it names it rather than papering over it with invention. An unsolved case is allowed to remain unsolved. There is more respect, and frankly more interest, in an honest “we do not know” than in a satisfying answer the evidence cannot bear.

What “verified” actually means here

We are careful with the word verified, and we use it in only one place. It does not mean a draft was researched, and it does not mean a machine checked it. It means a person — reading against the sources — has confirmed that the names, dates, sequences, and locations match the record, that each claim is supported, and that the tone stays where it belongs. That human sign-off is the line between a promising draft and something we are willing to put in your ears while you stand on a real street. Reserving the word protects it. If verified could mean anything, it would mean nothing, so we let it mean only that.

Why we do it the slow way

Checking by hand is slower than shipping on research alone, and it means some cases we would like to tell are simply not ready. We think that is the correct trade. A true-crime walk remembers real people and passes through real neighbourhoods, and it owes both of them accuracy. When you open a case and begin the walk, you should be able to trust that what you are hearing is the documented past, weighed and confirmed — fact, not folklore.
