Brennan confronted a man he saw standing on the neighbour's verandah.^[5] When he tried to make his escape, Brennan blocked his path at the garden gate and the pair then grappled.^[4] During the struggle, Brennan was shot in the chest by a small automatic pistol that the intruder had managed to draw from his overcoat with a free arm.^[4] Brennan died at the scene.^[6] The gunman was chased by two other bystanders but was able to get away.^[7]

An investigation revealed that the gunman, likely aged 25 to 30, had earlier been seen scoping the area, and the police were able to get a good description of his appearance.^[4][8]

The police were unable to locate the suspect and after three months had elapsed the City Coroner gave a finding that Brennan had been murdered by a "person unknown".^[9][10]

Redston headed to a friend's house, planning to spend the day at the Curtin Tip.^[12] After waiting for a short period of time, Redston left the area and was not seen again until his body was discovered the next day. The next day, after a search with police dogs, Redston's body was discovered among the reeds in a creek bed in Curtin. He had been bound, strangled, wrapped in carpet, and then moved to the location.^[12]

On 27 September 1966, Redston was sent by his mother to buy ice cream for himself and his brother from the local shops. Redston however sent his brother away and headed to his friend's house, planning to spend the day at the Curtin Tip.^[12] After waiting for a short period of time, Redston left the area and was not seen again until his body was discovered the next day among the reeds in a creek bed in Curtin. He had been bound, strangled, wrapped in carpet, and then moved to the location.^[12]

A manhunt began and quickly turned up the descriptions of two suspects: "a blond-haired youth, aged 13-15", and a young man.^[13] Both men were seen with Redston earlier that day, and both were seen leaving the tip where Redston is believed to have been murdered.^[14]

No-one was ever officially charged of the crime.^[15]

McKim-Hill left Rockhampton at 8:00am on 9 March 1967, and travelled south to Calliope.^[17] Her car was found abandoned at 3:00am the following morning on the Gladstone by-pass road, three kilometres north of Benaraby.^[17]

Her body was found on 26 March 1967 at Collard Creek alongside the Dawson Highway, north-east of Biloela, eighty kilometres from where her car had been found.^[17][18]

During the investigation, police followed two lines of enquiry.^[19] They searched for four men seen travelling in the local area in a Ford Customline, but they were never located.^[20][21] In 2011, the police said those men were still of interest.^[19] A truck driver carting tallow was also of interest to police during the investigation.^[19]

An inquest into McKim-Hill's murder commenced on 6 November 1967 and concluded on 16 January 1968, during which time 26 witnesses gave evidence and a solicitor for the victim's family named a German truck driver as a likely suspect.^[22]

On 30 July 1985, former Vice Squad officer Mick O'Shea told The Advertiser newspaper that the group involved were Vice Squad officers and that there was a cover-up to protect them. On 5 February 1986 three former Vice Squad officers, Brian Hudson, Francis Cawley and Michael Clayton, were charged with the manslaughter of Duncan. Cawley and Clayton eventually went to trial in 1988 with both being acquitted of the charges on 30 September after refusing to testify.^{[24][26][27][28]} A further allegation was later raised that there had been an attempt to influence a juror to find the two officers charged not guilty.^[29] A police task force was set up, reporting to Parliament in 1990 that there was insufficient evidence to charge any person with the murder. Repeated calls for a Royal Commission have been ignored.^[25]

At the time, various rumours regarding the murder attributed it to specific issues relating to prostitution and the way it was being handled by police and government in Perth, but no evidence of this was made public.^[33][34][35]

The murder, and the implied connections with issues relating to policing of the sex industry, resulted in a Royal Commission being held.^[36] On the thirtieth anniversary of the murder a cold-case review of the case was announced.^[37] An opinion was canvassed that no solution of the case was likely.^[38] In 2014, another cold-case review was launched by WA Police. The following year, the Corruption and Crime Commission confirmed it had received new information about the murder.^[39]

On 6 March 2017, the ABC Television documentary series Australian Story aired a story titled "Getting Away With Murder"^[40] which revealed that a coronial inquest would be conducted in 2017.^[41] The inquest commenced on Tuesday 29 August^[42] The public hearing was adjourned on 20 December 2017 and resumed on 23 July 2018. After a week, it was again adjourned for 6 months, "allowing new leads to be followed up and two scientific investigations to be completed". Coroner Barry King acknowledged limitations but had not given up hope. He urged persons with information to come forward.^[43]

On 15 July 1977, Mackay disappeared from the Griffith Hotel car park after having drinks with friends and has never been found. Stains from his blood group were evident on his van^[50] and the ground nearby, and his car keys were underneath the van.^[51] Nearby were drag marks, hair, and three spent .22 calibre cases.^[52]

In 1984, the coroner ruled Mackay had died of "wilfully inflicted gunshot wounds".^[53]

In 1986 hitman James Frederick Bazley was charged over the death.^[54] Bazley claimed he was innocent, blaming allegedly corrupt former Sydney detective Fred Krahe as the killer,^[55] but was convicted of conspiracy to murder Mackay.^[52] He was sentenced to life imprisonment.^[53]

In July 2012, 35 years after his disappearance, the New South Wales police offered a $200,000 reward for information on the whereabouts of Mackay.^[56]

There has been some speculation that Broadhurst was a victim of English Australian serial killer John Wayne Glover, who was convicted of murdering six elderly women on the Sydney North Shore district between 1989 and 1990, and is thought by police to have been responsible for other deaths.^[57]

In the documentary Unfolding Florence: The Many Lives of Florence Broadhurst, friends and employees of Broadhurst stated that they believed the killer may have been known to her, due to the presence of two cups of tea near her body, suggesting a meeting or appointment, and the killer's apparent knowledge of her factory's layout.

An autopsy reported the cause of death as a fractured skull and strangulation. ^[58]

The brutality of the murder was such that a pathologist described her injuries as being like those suffered by plane crash victims.

In 1978 a reward of $50,000 was offered to help solve the murder.^[62]

In May 1983, the government issued a reward of $20,000 for information which leads to the apprehension and conviction of the person or persons responsible for the disappearance and suspected murder of Jones. In 2010 the reward was increased to $250,000.^[69]

Despite no body having been found, Coroner Ian Fisher stated in his findings on 20 February 2002 that Jones was a victim of homicide. "I am satisfied that the missing person is dead," wrote the coroner. "I find that he died on or around the 3rd of November 1982 at the hands of a person or persons unknown".^[70]

New South Wales State Coroner Greg Glass found that Flannery was murdered most probably on or about 9 May 1985. He also found that the key to solving the murder lay with Roger Rogerson.^[76]

Police suspected foul play based on bloodstains found beside her red 1978 Honda Civic abandoned in the station car park^[80] and drag marks leading into the bushes, but no trace of her was ever found. Later, witnesses said Sarah got off the train and crossed the footbridge to the car park, where some people heard a woman shouting, ‘Give me back my keys.’^[82] A 21-day extensive air, sea, and land search with more than 250 police produced no results.^[83]

In May 2006, an inquest held by coroner Ian West,^[83] found MacDiarmid 'had met her death as a result of foul play but the exact circumstances were unknown'.^[84]

An initial State Government reward of $50,000 was increased after an additional $75,000 was offered by an anonymous benefactor.^[83] This was increased to $1 million, in 2004,^[84] and remains current.^[85]

Walker's body has not been found, although articles of her clothing were later found weighed down by rocks in the Nambucca River.^[89]

On 27 April 1991, Greenup's skeletal remains were found in bushland near Congarinni Road.^[89] An autopsy could not conclusively determine the cause of death, but noted that a skull injury was "consistent with a forceful penetration by a sharp instrument".^[91]

Police interviewed hundreds of people during the investigation, which remains active. In November 2006 NSW Police doubled the reward to $100,000.^[94]

On 9 April 1992, Chan's remains were found in a landfill area at Edgars Creek in the suburb of Thomastown.^[100] The skull had three bullet holes in the back of the head. The body had probably been there for 12 months.^[101]

On the afternoon of 5 November, Balmain, visited a client in the south-eastern Sydney suburb of Kingsford. After the two-hour appointment was over she had planned to meet friend Kate Brentnell for a drink. At 7.15 pm Revelle rang Kate Brentnell to say that she was about to leave her client and suggested that they meet at the Royal Hotel, Paddington. She did not keep that appointment.^[113]

The next day, Balmain's bag, shoes, make-up, diary, credit cards and keys to her Bellevue Hill flat were found scattered around several Kingsford streets.^[113] Police interviewed Balmain's client, who said that he had driven her to the nearby Red Tomato Inn at about 7.00 pm on the evening of 5 November. Police officers also questioned the escort agency's owners, but the enquiries resulted in no charges being laid.^[113]

The New South Wales government offered a reward of $100,000 for anyone who could provide information that would lead to the arrest of Balmain's killer.^[113] The reward for information is now up to $250,000.^[114]

Greg Domaszewicz was charged with murder, but was found not guilty in December 1998.^[118] A controversial 2006 inquest,^[122][123] found that he had contributed to the toddler's death and had likely disposed of the boy's body.^[124]

Gangitano is considered to be the second of the thirty-six Melbourne gangland killings between 1998 and 2010.

On 10 August 2020, the reward was raised to $1,000,000. The following day, 53-year-old Craig Henry Rumsby, a former neighbour of Bright's, was arrested for her murder, and also an assault with intent to rape against an 18-year-old committed in 1998.

On 30 June 2023, Rumsby was found guilty of Bright's murder and the assault on the 18-year-old.

On 7 August 2023, Justice Robert Allan Hulme sentenced Rumsby to 32 years imprisonment with a non-parole period of 24 years: Rumsby will be eligible for parole in 2044, at the age of 77.

In 2011, Anne Maree Wotherspoon, a 27-year-old woman from Hamilton South, was arrested in Newcastle CBD. She was subsequently charged with murder and then refused bail. Eventually three other people were arrested and charged for their alleged involvement. However, in April 2012, prosecutors dropped charges against all three of the accused.^[136]

In late 2013, the Supreme Court of New South Wales ruled that the confession of Wotherspoon was unreliable. Wotherspoon had told police that she and three others had stormed Gall's home seeking drugs and money. However, she made a number of errors in her confession including what weapon was used and the time of the murder. Justice Megan Latham found that Wotherspoon had been diagnosed with schizophrenia and drug-induced psychosis, causing delusions and hallucinations. Wotherspoon, an intravenous drug user, was recorded telling one of her boyfriends that she was going to confess with the intention of being imprisoned and being placed on a methadone program.^[137]

His associates Damien Cossu and Alfonso Traglia were with Radev at the time of the murder but claimed they could not identify the gunman, and were subsequently named by police as 'persons of interest'.^[140]

In 2012 a coronial inquest suggested that Newbery had been "attacked by a person or persons that were unknown." Police analysed hundreds of other similar robberies, investigated prisoners on parole, and took DNA swabs from every person who visited the shop on the day of the murder. Two samples found at the scene remain unidentified.^[149]

In 2017, Detective Inspector Peter Mahon stated, "We are still not sure of the motive, because if it was a robbery, you would have thought that they would have searched Frank and taken his money out of his wallet."^[151]

The last confirmed sighting of her alive was at 11:30pm on Saturday, 20 July. CCTV footage indicates she returned to her van sometime between 2 and 2:30am on 21 July. A DNA sample believed to belong to the murderer was found by police, and checked against Victoria Police's database with no luck. It was also checked against 1500 people including people in St Kilda at the time of the murder, locals with a violent past and registered sex offenders.^[152]
