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.

In the early hours of 12 October 1988, two young constables, Steven Tynan, 22, and Damian Eyre, 20, stopped to check an abandoned car on Walsh Street in South Yarra, Melbourne. Within minutes both were dead, gunned down in what police believed was a professional ambush by an armed robbery gang taking revenge for a suspect shot dead by detectives hours earlier.
Four men, among them Victor Peirce, stood trial in 1991 after one of the largest investigations Victoria Police had ever run. All were acquitted, and the case has never been officially solved.
In 2005, Peirce's own wife Wendy, who had once given him a false alibi and was later convicted of perjury for it, broke her silence and told the press that her husband had planned and carried out the killings himself.

One October night in 1965, Ian Brady and his lover Myra Hindley brought a seventeen-year-old back to their home near Manchester, where Brady killed him with an axe in front of Hindley's brother-in-law, David Smith, whom they had wrongly taken for a kindIan Brady and Myra Hindley brought 17-year-old Edward Evans back to their home near Manchester after Brady had approached him at Manchester Central station. Brady attacked Evans with a hatchet in front of Hindley's brother-in-law, David Smith, whom Brady apparently believed could be drawn into his criminal world, before strangling Evans with electrical flex.
Smith was horrified and notified police the next morning. Police Superintendent Bob Talbot arrived at the house wearing a bread deliveryman's overall over his uniform. Inside, Brady was lying on a divan writing to his employer about his injured ankle. Talbot said he was investigating "an act of violence involving guns", and Hindley denied that any violence had occurred.
When officers asked for the key to a locked spare bedroom, Hindley claimed it was at work. Police offered to take her there to retrieve it, at which point Brady told her to hand it over. Inside the room, they found Evans's body, and Brady was arrested on suspicion of murder.
Peter Sutcliffe hammered 20 year old Jean Jordan to death near a cemetery in Manchester, then realised the brand new £5 note he had just paid her was traceable straight back to his wage packet. Nine days later he returned in the dark to retrieve it, could not find it, and instead mutilated her body and attempted to cut off her head.
The note had been lying just outside the police search area the whole time, in her handbag under a fence. Detectives traced it to a Bradford pay run and interviewed thousands of workers, including Sutcliffe himself, twice. His alibi held, the inquiry stalled, and the man holding the incriminating fiver walked free for years before he was finally caught as the Yorkshire Ripper.
