Why do we find it hard to believe that the smiling nurse Lucy Letby was a serial killer? | Martha Gill

The nurse's case shows the dangers of believing that women like her could not possibly commit murder

Why do so many people still think Lucy Letby is innocent? It's worth asking, because last week yet another blow was dealt to the theory. In a retrial of one of the charges against her, Letby was found to have attempted to murder another newborn baby, and handed a 15th life sentence.

In the past 10 months, we have heard less about Letby: reporting has been restricted while the trial was going on. In the meantime, she has all but exhausted the appeals process; her second application was denied. In a ruling published last Tuesday, appeal court judges said none of her legal challenges was arguable, and that the criteria for fresh evidence had not been met.
