New DNA lead in Murial Drinkwater's brutal 1940s murder

More than 70 years after her death, 12-year-old Muriel Drinkwater's murder could be close to being solved.

She was found brutally raped and shot twice in 1946 after disappearing on her walk home from school.

The prime suspect is a convicted child killer who is also suspected of being 'Jack the Stripper', a man responsible for a series of murders of women in London during the 1960s.
