The little girl in this photo grew up to be called the ‘most evil’ woman in history.

A small, smiling girl in a school uniform, gap-toothed and bright-eyed, staring back at the camera with the kind of uncomplicated happiness that belongs only to childhood.

She looks like any other little girl. A future teacher, maybe. A doctor. Someone who would grow up to help people.

She became a nurse.

And for years, the parents of the tiniest, most vulnerable patients in her care believed she was exactly that, a helper. A protector.

Someone who stood between their newborn babies and the terrifying fragility of those first days of life. They trusted her completely. That trust would cost some of them everything.

A normal girl from a normal town

She was born in 1990 in Hereford and raised in Cheltenham, by all accounts an unremarkable, pleasant child.

She studied nursing at the University of Chester, graduating in 2011, and took up a post at the Countess of Chester Hospital’s neonatal unit shortly afterward.

Colleagues described her as dedicated, caring, even passionate about her work with premature and sick newborns. She wore colorful scrubs. She remembered patients’ names. Nobody suspected a thing.

But between June 2015 and June 2016, something monstrous was unfolding inside that ward.

The babies who kept dying

In any neonatal unit, tragedy is not uncommon. Premature babies are fragile. Deaths happen.

But the death rate on this particular ward during this particular period was not just high, it was statistically extraordinary.

Consultant doctors began to notice a pattern. Collapses. Deteriorations. Deaths. And one name kept appearing on the shift rosters when it happened.

Concerns were raised internally as early as 2016, per RNCI, but hospital management was slow to act.

Doctors escalated their worries repeatedly, only to be met with resistance and, in some cases, told they were wrong to point fingers. It would take until 2017 before police were finally informed, and 2018 before an arrest was made.

By then, it’s believed she had already harmed or killed 17 babies.

The crimes

The methods were almost unthinkable. Prosecutors would later allege that she injected air into babies’ bloodstreams, force-fed them milk, and poisoned them with insulin, all while their parents sat just feet away, sometimes holding their child’s hand, believing the worst was simply the cruelty of nature.

Seven babies died. Ten others were left with serious harm. The youngest victims were just days or hours old. One family lost twins. She is alleged to have attacked some of the same babies multiple times.

The jury heard that she kept notes on the deaths. That she had written, in her own handwriting, on a Post-it note found in her home: “I am evil, I did this,” Tudum reports.

She denied everything.

The trial

The trial began at Manchester Crown Court in October 2022 and became one of the longest and most complex criminal proceedings in British legal history, running for nearly a year, per ITV.

Jurors heard from hundreds of witnesses. Medical experts testified about collapsed lungs, air embolisms, and insulin levels that had no innocent explanation. Grieving parents gave evidence about the nights their worlds ended.

She sat in the dock throughout, composed and largely expressionless. She did not testify in her own defense.

On August 17, 2023, after deliberating for 22 days, the jury returned its verdicts. She was found guilty of murdering seven babies and attempting to murder six more. She was sentenced to a whole-life order, meaning she will never be released.

The judge told her she was ‘calculated, cold-blooded’ and had demonstrated ‘cruel and pitiless’ behavior.

Outside the court, families wept. Some with grief. Some, finally, with relief.

The controversy that followed

The case did not end with sentencing. In the months that followed, a group of international medical experts published findings arguing that the medical evidence used to convict her was flawed, suggesting that several of the deaths attributed to her could have had natural causes.

A Netflix documentary examined the investigation and the questions still swirling around the evidence. The Criminal Cases Review Commission began examining the case.

This controversy matters. It does not erase the jury’s verdict, reached after nearly a year of exhaustive evidence. But it ensures the case will remain contested, scrutinized, and debated for years to come, not least by the families who deserve certainty above all else.

That little girl in the school photograph, smiling her gap-toothed smile in Cheltenham, her name is Lucy Letby.

She is now 34 years old and is serving a whole-life sentence at HMP Bronzefield.

The neonatal unit where she worked has long since been reformed. The Countess of Chester Hospital commissioned an independent inquiry into how warning signs were missed and why it took so long for doctors’ concerns to be heard.
