A twisted teenager who killed his ex-girlfriend’s baby by brutally shaking him to death told police that they were ‘boring’ during an interview. Carl Alesbrook, who was 16 at the time, murdered four-month-old baby Elijah Shemwell in January 2022 just weeks after meeting his mother India Shemwell. Elijah died three days after he was found limp, pale and drowsy at his mother’s messy flat in Belper, Derbyshire.
