Lucy Letby gave baby morphine overdose years before first murder, inquiry hears

Newborn received 10 times the correct amount of painkiller and could have died if colleagues had not spotted error

Lucy Letby gave a potentially fatal dose of morphine to a newborn baby two years before she murdered her first victim, an inquiry has heard.

The infant received 10 times the correct amount of the painkiller at the end of a night shift in July 2013 and could have died if colleagues at handover had not spotted the error an hour later.
