Eric Edgar Cooke

In November 2020, Stan released an original four-part docuseries After the Night, covering the story of Cooke's murders.

Despite Cooke's 1963 confession, Beamish served 15 years, while Button was sentenced to 10 years and ended up serving five. In 2002, the Court of Criminal Appeal quashed Button's conviction. Button's success opened the way for an appeal by Beamish, who was acquitted in 2005. In both cases, the appeal judges found that the murders had most likely been committed by Cooke. On 2 June 2011, Beamish was granted a A$425,000 ex gratia payment by the Western Australian government.

In March 2009, the second season of Crime Investigation Australia featured an episode about Eric Edgar Cooke. In September 2016, Felon True Crime Podcast also reviewed Cooke's crime spree in detail.

A 2000 memoir by Robert Drewe, The Shark Net – later made into a three-part television series – provided one author's impressions of the effect the murders had on the Perth of that era. According to Drewe, more people bought dogs for security, and locked back doors and garages that had never been secured before.

Over subsequent decades, Button and his supporters – including Christian and Blackburn – continued to press for a retrial, a campaign that included a well-publicised 1998 simulated reenactment of Anderson's death, conducted by crash test experts, with both a Holden matching one believed to have been used by Cooke on the night in question, and three Simca Aronde sedans like the car owned by Button, which were driven toward a crash test dummy. The dummy was thrown over the roof of the Holden, as Cooke had claimed, and the damage sustained matched the records of a panelbeating business that had, in 1963, repaired the vehicle driven by Cooke. The experts found that the sun visor flexed when hit by a body and returned to its original shape, without cracking the paint. An expert from the United States was brought to Australia to prove Cooke's car, not Button's, hit Anderson.

Cooke, as "The Nedlands Monster", features in Tim Winton's 1991 novel Cloudstreet and the subsequent 2011 television adaptation. Cooke is also referenced in Craig Silvey's 2009 novel Jasper Jones.

In Randolph Stow's final novel, The Suburbs of Hell (1984), he acknowledged that there was a delayed response to the horror of Cooke's murders, which he transposed for fictional purposes from his WA origins to a town resembling the English town he then inhabited, Harwich. Suzanne Falkiner's biography of Stow revealed that it piqued his sense of humour that Perth denizens at the time of the murders would knock on doors and say 'It's the Nedlands Monster'.

After 13 months in New Division, Cooke was hanged at 8 am on 26 October 1964 in Fremantle Prison. Ten minutes before the sentence was carried out, Cooke swore on the Bible that he had killed Brewer and Anderson, claims which had been previously rejected because other people had already been convicted of those murders. Cooke was the last person to be hanged in the state of Western Australia. He was buried in Fremantle Cemetery, above the remains of child killer Martha Rendell, who was hanged in Fremantle Prison in 1909.

The police investigation included fingerprinting more than 30,000 males over the age of 12, as well as locating and test-firing more than 60,000 .22 rifles. After a rifle was found hidden in a Geraldton wax bush on Rookwood Street, Mount Pleasant, in August 1963, ballistic tests proved the gun had been used in the McLeod murder. Police returned to the location and tied a similar rifle, rendered inoperable, to the bush with fishing line and constructed a hide in which they waited in case someone returned for it. Cooke was noted loitering in a car in the area several times, and was apprehended when he tried to collect the weapon just after midnight on 1 September.

Cooke began confessing to his many crimes, including eight murders and fourteen attempted murders. He was convicted on a charge of murdering Sturkey, one of Cooke's five Australia Day shooting victims. In his confessions, Cooke demonstrated an exceptionally good memory for the details of his crimes irrespective of how long ago he had committed the offences. For example, he confessed to more than 250 burglaries and was able to detail exactly what he took, including the number and denominations of the coins he had stolen from each location. The book Presumed Guilty by Bret Christian includes details of Cooke's confession, made over two days in September 1963 at Fremantle Prison to his Legal Aid lawyer Desmond Heenan. "I have a great respect for the law, although my actions don't show this," Cooke said.

Cooke pleaded not guilty on the grounds of insanity. At the trial, Cooke's lawyers claimed that he had schizophrenia, but this claim was dismissed after the director of the state mental health services testified that he was sane. The state would not allow independent psychiatric specialists to examine Cooke. Cooke was convicted of wilful murder on 28 November 1963 after a three-day trial by jury in the Supreme Court of Western Australia before Justice Virtue. He was sentenced to death by hanging and, despite having grounds to appeal, he ordered his lawyers not to apply, claiming that he deserved to pay for what he had done.

John Button was wrongly convicted for the death of his girlfriend, Rosemary Anderson, who died in Royal Perth Hospital (RPH) at 2:30am in the early morning of 10 February 1963. Anderson had spent the previous day with Button in celebration of his nineteenth birthday; they had a minor argument at his home that night which culminated in her deciding to leave the Button house and walk home. Button followed her in his car at different stages, attempting to have her accept a lift home. At one stage Button parked his car to smoke a cigarette; upon resuming driving he turned into Stubbs Terrace, in Shenton Park, and discovered her lying on the ground beside the road. John Button took his injured girlfriend to a local doctor and she was subsequently transferred to RPH by ambulance. The police became involved and interviewed Button who, after intense questioning and upon receiving notice of Anderson's death, broke down and confessed to being responsible for her hit & run death. After conviction for manslaughter, the courts dismissed Button's initial appeal, even though Cooke had by this time confessed to the crime and provided details that only the culprit could have known; in particular, the judges did not believe Cooke's claim that Anderson's body was thrown "over the roof" of a Holden EK sedan without damaging its external windscreen sun visor, as Cooke had claimed.

Darryl Beamish, a deaf-mute, was convicted in December 1961 of murdering Jillian Macpherson Brewer, a Melbourne heiress who was struck with a hatchet and stabbed with scissors, in 1959. Beamish was initially sentenced to death, but the sentence was commuted to imprisonment, and a later investigation, supported by Post Newspapers owner Bret Christian led to his conviction being overturned. Beamish's initial appeal was dismissed because the court did not believe Cooke's evidence. The prosecution claimed that Cooke's confessions were an attempt to prolong his own trial, and the then-Chief Justice of Western Australia, Sir Albert Wolff, called Cooke a "villainous unscrupulous liar". The police case against Beamish is detailed in Christian's book Presumed Guilty.

On 14 November 1953, Cooke, then aged 22, married Sarah (Sall) Lavin, a 19-year-old waitress, at the Cannington Methodist Church (demolished 1995). They ultimately had a large family of seven children, four boys and three girls.

During the 1950s and early 1960s, people in Australia frequently left cars unlocked and often with the keys in the ignition. Cooke found it easy to steal cars at night and sometimes returned stolen vehicles without the owners becoming aware of the theft. In September 1955, after having crashed a car and requiring hospitalisation, Cooke was sentenced to two years hard labour on a charge of unlawful use of a motor vehicle; he was ultimately released from Fremantle Prison just prior to Christmas, 1956. After his release, he took to wearing gloves while committing crimes, in order to avoid leaving fingerprints, which had been his undoing in relation to his prior breaking and entering convictions.

Cooke was also placed in orphanages or foster homes on occasion. Much like his mother, he would hide underneath the house or roam neighbouring streets just to escape a night of his father's violence. He was frequently hospitalised for head injuries and had suspected brain damage because of his accident-proneness. Later it was questioned whether these 'accidents' were due to repressed suicidal tendencies. Cooke also had recurrent headaches and was once admitted to an asylum. His reported blackouts later stopped after an operation in 1949.

On 12 March 1949, police finally caught up with Cooke and found evidence at his grandmother's house, where he was living. Cooke's fingerprints were matched to those found in other open cases. On 24 May 1949, Cooke was sentenced to three years in prison after being arrested for arson and vandalism; he was convicted on two charges of stealing, seven of breaking and entering and four of arson. He left many fingerprints and easy clues for detectives which would teach him to be more careful in his future crimes.

Eric Edgar Cooke (25 February 1931 – 26 October 1964), nicknamed the Night Caller and later the Nedlands Monster, was an Australian serial killer who terrorised the city of Perth, Western Australia, from September 1958 to August 1963. Cooke committed at least 22 violent crimes, eight of which resulted in deaths.

Eric Edgar Cooke was born on 25 February 1931 in Victoria Park, a suburb of Perth, Western Australia, and was the eldest of three children. He was born into an unhappy, violent family; his parents married solely because his mother, Christine Edgar, was pregnant with him. His alcoholic father, Vivian Cooke, beat the boy frequently, especially when the boy tried to protect his mother. Christine would sleep in the staff room at her job in the Como Hotel to avoid going home and being beaten by Vivian.
