Expert's new Lucy Letby 'smoking gun' theory claims evidence 'proves she's innocent'

While Lucy Letby remains in prison serving over a dozen whole-life sentences, new evidence unearthed has cast the entirety of the prosecution's case into doubt, an expert has said

A medical expert has claimed that new evidence in convicted baby killer Lucy Letby's trial "proves she is innocent".

One expert investigating the new findings has said the case has now become a "smoking gun" that brings Lucy's guilty verdicts into doubt. Letby is currently serving over a dozen whole-life terms in jail after she was found guilty of killing seven newborn babies.

While Lucy remains in prison for the murder of the babies - as well as the attempted murder of eight others, her legal team has been collecting more evidence to build another appeal case. Now, a medical expert has backed calls to dismiss the initial evidence used to convict the former nurse.

During her time at the Countess of Chester Hospital, nearly three times as many newborn babies died. The incidents occurred between 2015 and 2016, while Lucy was working on the ward before she was moved to work in an administrative role.

Throughout her trial, Lucy was branded a callous baby killer, using the trust she had gained working in the neonatal intensive care unit to cause pain and suffering to babies and families alike. She was accused of a host of vile ways of killing the children, all while never leaving a trace of her crimes.

But in recent weeks, further evidence has been putting the prosecution's case against Letby into doubt. Now, questions are being raised over the health of two little babies who were seemingly poisoned with insulin.

Looking at the new evidence, Professor Geoff Chase and mechanical engineer Helen Shannon, released a new report examining the details of each case against Lucy. The 173-page long documentation will be used by the defence team and has already been submitted to the local commission to evaluate.

Prosecutors had argued that the babies had been poisoned with insulin, using blood tests to prove this had been the case. These cases were used as proof by prosecutors that someone at the hospital was directly harming babies.

Letby was then convicted of giving insulin to Child F and Child L through their feed bags during her time in the hospital. However, according to the new evidence, no insulin had allegedly ever gone missing - with Professor Chase and Shannon now allegeding that at least seven vials of insulin going missing would have been spotted by staff.

Speaking to the Telegraph, Professor Chase insisted: "The trial stated no insulin was missing and it would require only a very small drop. If injected intravenously yes, this is true, but with adsorption, or sticking, it would require between 1.2 teaspoons to six to seven vials.

"If no insulin is missing, there is no way to commit that crime," he added. "Insulin sticking to lines, bags, tubes is a known thing and it can significantly impact, for example, insulin pump use among small children."

Professor Geoff would later describe the lack of missing insulin as the "smoking gun" of the case. He insisted that if no insulin was missing, then there could be no poisoning, as was initially believed.

Letby has always strongly denied all the allegations put to her, even after she was convicted. Her sentences are now being looked into by the Criminal Cases Review Commission, a body used to prevent potential miscarriages of justice.

Letby's case will be featured on a new BBC Panorama special tonight, Lucy Letby Who to Believe?, at 8pm.
