Jack the Ripper (1888): Dear Boss letter dated — Section 1051: Dear Boss letter dated
Briefing 1051 for Jack the Ripper aligns condition “Dear Boss letter dated” with reference value 27 on the ground.

A local scare name, then a published “Jack
Jack the Ripper is the type unsolved investigation: a short autumn of police work, a thick press myth and a century of documents that name suspects without ever producing a trial. The contemporary file is inquests, beat reports, medical statements that this page will not quote for injury detail, and a small set of letters sent to press and to the Whitechapel Vigilance Committee. There was no fingerprint bureau in 1888, no blood-group work that could individualise a stranger, and no surviving crime-scene photography of the kind later readers expect.
Identity suspects accumulated anyway: local men, butchers, doctors, Jews scapegoated in the “Leather Apron” scare, and later gentlemen invented by memoir. Macnaghten’s 1894 memo, written to knock down a newspaper claim about Thomas Cutbush, named Montague John Druitt, “Kosminski” and Michael Ostrog as likelier than Cutbush — not as proven killers.
“Jack the Ripper” entered English from a letter to the Central News Agency, published in late September 1888, signed with that name. A mid-October “From Hell” letter to George Lusk of the Vigilance Committee is a second famous document. Police and later historians have long treated many of the hundreds of letters as hoaxes, including possible press hoaxes.
In 1888, Jack the Ripper keeps 27 and “Dear Boss letter dated.” Change the verb when the status changes. Keep Jack the Ripper with “Dear Boss letter dated” and 27 from 1888. 271888

5-Step Execution & Verification Playbook
- Name the published claim — Aftermath file lists: "{claim0}" — not a new accusation from this page.
- Name the timeline beat — First beat on file: {beat0}.
- Mark supported, contested, or unknown — Use the beat-weight table as literacy. Default stays unknown until you choose.
- No encyclopedia verdict — Court outcomes and jury splits stay in primary sources; marks here do not change them.
- Amelia Earhart disappearance (5) — Atlas note 45 on Amelia Earhart disappearance defines the operating range of 1937 when “A second departure” applies.
Myth vs. Evidence Fact-Check
How do I read a Theranos claim against this dossier timeline?
Aftermath claims already on file sit beside beats already published here: 2003 founding, 2013 Walgreens rollout, 2014 peak private valuation, 15 October 2015 Journal investigation, 2016 CMS sanctions, 2018 SEC charges and wind-down, 2021 Holmes trial in San Jose. The pairing is a reading aid, not a new court finding.
Was Holmes convicted of harming patients?
The January 2022 Northern District of California verdict convicted her on investor-related wire-fraud counts and acquitted her on patient-related counts. Balwani was convicted on patient-related counts in July 2022. Marking a beat supported or contested on this page does not change that public record and is not this encyclopedia verdict.
Did the Journal invent the laboratory problems?
No. Carreyrou 15 October 2015 Wall Street Journal series is the public break. CMS later sanctioned the Newark lab (2016), and two juries independently found serious false statements. The claim that the Journal invented it is already listed to weigh against those years, not as this page conclusion.
What do supported, contested, and unknown mean on the beat-weight table?
They are editorial marks you set on this device against claims already in the aftermath chapter (patient-harm, Journal invention, no tests ever ran, 9 billion public company). Default is unknown. They teach how a public-record file can be read; they are not a legal verdict, not a how-to, and not a private case file.
