Mary Bell, the 10-Year-Old Killer

Mary Bell is likely currently living a quiet and simple life with her daughter. But Mary's past is so shocking, she was granted lifetime anonymity and her current whereabouts are unknown. This week, Savannah details the killings of 2 young boys, Brian Howe and Martin Brown, at the hands of then-10-year-old Mary Bell. Mary lived a troubled life, being abused and unloved by her own mother. Mary showed terrifying signs of aggression towards her classmates, until ultimately letting her anger get the best of her and strangling 2 boys and carving a calling card into the stomach of one of them. Savannah brings you the timeline of events as well as details of the incredible trial of one of Britain's youngest serial killers in history. Get 10% Off by visiting!
