Lucy Letby: Latest Verified Information, Timeline, and Key Sources

Few criminal cases leave as many open questions as the Lucy Letby conviction. A former neonatal nurse was found guilty of murdering seven babies and attempting to murder seven others — a verdict that should have brought closure. Yet the slow machinery of the Thirlwall Inquiry, a key prosecution witness under investigation during the trial, and unresolved complaints about workplace culture have kept the story alive. Here is what is verified and what remains unproven, drawn from official records and authoritative reporting.

Convicted of murders: 7 ·
Convicted of attempted murders: 7 ·
Years active: 2015–2016 ·
Sentence: 15 whole‑life orders (life imprisonment) ·
Inquiry status: Thirlwall Inquiry report delayed to May 2026

Seven key facts, one pattern: the case rests on a narrow set of official sources, with many surrounding details still contested.
