She is white and she is a cold-blooded murderer. Lucy Letby sadistically killed seven babies and attempted to kill six more. She worked as a neonatal nurse at the Countess Chester Hospital in Manchester, UK.
If she was Black or brown and so many babies had died or whose health had deteriorated on her watch, she would have been investigated after the very first death.
No one would have waited until she killed six babies before starting an investigation. The fact that she was white played a huge role in how she literally got away with murder, or more accurately, multiple murders, for many years.
