There was also a new witness - neonatologist Shoo Lee, from Toronto, the co-author of a 1989 medical research paper about air embolism in neonatal babies. An air embolism occurs when one or more air bubbles enter a vein or artery, causing a block in circulation. The consequences can be fatal.
Letby was found guilty of injecting air into the bloodstreams of some of the infants, causing air embolism. Prosecution experts had based some of their evidence on Dr Lee’s paper, although he hadn’t been called to give evidence.
Now he was appearing on behalf of the defence.
During the trial, much was made of changes in skin colour observed on some of the babies, which it was suggested were symptomatic of air embolism. The prosecution cited Dr Lee’s paper in support of this, and paediatric consultant Dr Ravi Jayaram told the court a “chill went down (his) spine” in June 2016 when he read the research and believed it fitted with what he’d seen on babies in Chester.
But nobody had checked with Dr Lee. The point he now made, via webcam from 3,500 miles away, was that only one, very specific skin discolouration was diagnostic of air embolism, and none of the babies in the case had displayed this exactly.
For Letby’s defence, it was a basis for appeal. The prosecution disagreed. They argued that all of the instances of skin discoloration in the Letby case were consistent with air embolism, and some of these could be proven using Dr Lee’s own diagnostic method.
They said Dr Lee hadn’t been shown any of the eyewitness testimony from the trial, or any of the babies’ records – and so was not qualified to weigh in now.
Sitting on the uncomfortable wooden benches of court 4, one couldn’t help but wonder why this development hadn’t been aired at the trial. Letby’s lawyers were arguing the science was too weak to support as many as nine of her 14 convictions.
