John Wayne Glover, later known as the Granny Killer, followed 86-year-old Doris Cox along Spit Road in Sydney's Mosman to her retirement village in 1989, then dragged her into a secluded stairwell and smashed her face into a brick wall.
Cox survived, one of the few to live through an attack that would later be linked to a string of killings targeting elderly women. But she had Alzheimer's, and her account of the assault was so confused that detectives were steered toward hunting a much younger suspect, a misdirection that bought Glover more time before he was finally caught.
