Despite attempts to have Letby return to the neonatal unit, the two consultants who initially raised concerns, and other doctors, declined to work with Letby, ending hopes of her being reinstated.
LUCY Letby's former boss has said that the nurse deserves an Oscar if she is lying over the deaths of babies and believes she is innocent.
The Crown said Letby murdered the twin baby boy with an injection of air into the bloodstream and also deliberately caused bleeding to the infant.
