Revision history

Version 316 Aug 2026, 13:54current
Removed the invented calendar dates "August 12" and "August 13", reverting to the weekday references the fact set supplies (Wednesday morning, Thursday, Wednesday press conference); only August 11, 2026 and September 11 remain, as given. Stripped all names from the dek. Consolidated the victims' names and the suspect's name into a single sentence in the opening paragraph so the surname appears in one sentence only; every later reference is "the teenager" or "the 17-year-old". Kept and sharpened the sourced handling of the three conflicts (as-of point, stated_by, venue) and led with the best-supported city-level location while naming localnews8.com's venue-level description in the same breath.
Version 216 Aug 2026, 12:26
Removed all personal names from the headline and dek, which now describe the victims by age and the accused only as a 17-year-old member of the household. Consolidated every name into one sentence in the second paragraph, so the suspect is named exactly once and no other sentence carries the surname; later references use "the teenager" and "he." Kept all sourced facts: victim names and ages as released by prosecutors, the date 2026-08-11, the charges, the without-bail order and mental health evaluation, and the September 11 probable cause hearing printed as given. Retained the sourced ranges for the disputed points (who stated the deaths, the day the two were found — "el martes (Tuesday)" per localnews8.com and "Tuesday" per keyt.com — city versus venue for the location, and welfare check versus wellness check) with both outlets named. Preserved Marian Ryan's quotes in the exact wording of the fact set, including the Spanish rendering, along with the line noting the not-guilty plea and that no cause or motive has been established.

How we work

This site models an investigative reporter rather than a wire desk. The aim is the most complete, accurate and timely account we can assemble — all three, not a trade between them. Reports go out within minutes of the coverage they are built from, carrying context a newsroom would otherwise need a day and a records request to gather: what has happened at this place before, what the operator’s record is, which aircraft it actually was.

Reports are built from primary sources — accident and court records, official registries, weather observations, agency statements — and from reputable news organisations, each named where their reporting is used. Facts are extracted before anything is written, and every one must be supported by a quotation found in the source itself; the model that writes the report is given only those verified facts and never sees the article, so it cannot introduce a detail no source stated.

Where sources disagree we publish the disagreement, attributed, rather than picking a figure. Where a fact comes from a record rather than a reporter, we say so, and the language matches: an instrument reading is never described as something anyone confirmed. Some things are deliberately withheld — a suspect is not named until an agency names them on the record, victims until families or officials release them — and corrections appear as visible revisions, never as silent edits.

None of that makes a report true. A quotation check proves a source said something, not that it was right, and an automated system can be confidently wrong in ways the checks do not catch. If something here is wrong, the feedback above is how it gets found. The full methodology, including what we refuse to publish.
