In the U.K., many have been following the trial of Lucy Letby, a neonatal nurse working in Cheshire, England, convicted this week of murdering seven infants and attempting to murder six more. Some of those who survived have lifelong brain damage because of their injuries.

There are many disturbing features of the case, not the least of which is the handling of Letby by hospital management. When senior doctors raised concerns about Letby, they were told to apologize to her and ordered to stop making allegations under threat of “consequences.”

But those doctors have since been vindicated in court. Today, Letby was sentenced to life imprisonment. The British government has ordered an independent inquiry into how clinicians’ concerns were handled.

As for what we know about Letby’s victims, many of the specifics will never be revealed due to the anonymity orders by the judge before the trial began.

Two of Letby’s victims were brothers — two of three identical triplets, conceived naturally at odds of 200 million to one. The Daily Mail reports, “Letby injected both boys with air. Their parents begged for their surviving son, who cannot be named for legal reasons, to be moved to a more specialist hospital, where he did well and was quickly discharged.” Letby also targeted three sets of twins.

In his sentencing remarks, Judge Goss described Letby’s crimes as a “cruel, calculated and cynical campaign of child murder,” and her victims as “fragile” and “extremely vulnerable.”

He’s right, of course. Killing small, defenseless children is one of the greatest evils known to man. It is worth noting that Letby’s youngest victim was born at just 23 weeks gestation, which is under the legal abortion limit.
