In brief
Seven pediatric and toxicology specialists have raised concerns about the insulin poisoning evidence used to convict Lucy Letby, a nurse sentenced to life for the deaths of seven infants.
Seven pediatric doctors and toxicology experts have cast serious doubts on the validity of the insulin tests that were pivotal in the conviction of Lucy Letby, a nurse sentenced to 15 life terms for the murder of seven babies at a British hospital. On Thursday, Ms. Letby's lawyer submitted a new report to the Criminal Cases Review Commission (CCRC) in a bid to have her case re-evaluated for possible miscarriage of justice.Letby, who worked in a neonatal unit, was found guilty in 2023 of intentionally inflicting harm on infants, which included methods such as air injections and insulin poisoning. In the report presented to CCRC, experts—including a forensic toxicologist and a professor of forensic science—argued that the evidence regarding insulin and C-peptide testing presented at Letby's trial was fundamentally flawed. Their summaries indicated, "Our inescapable conclusion is that this evidence significantly undermines the validity of the assertions made about the insulin testing presented in court."Letby has steadfastly maintained her innocence, and her conviction has been subjected to increasing scrutiny after numerous reports—including a detailed article in The New Yorker—questioning the legitimacy of her guilt. Despite these revelations, Letby's legal attempts to appeal have so far been consistently denied, leaving many to speculate about the potential for a reevaluation of her case amid growing doubt over the testing protocols used against her.
