Jane Nartare Beaumont (born September 10, 1956), Arnna Kathleen Beaumont (born November 11, 1958), and Grant Ellis Beaumont (born July 12, 1961), often called the Beaumont children, were three Australian siblings who disappeared from Glenelg Beach near Adelaide, South Australia, on January 26, 1966 (Australia Day). This case remains unsolved and is suspected to involve a kidnapping and murder.

Police investigations showed that on the day of their disappearance, witnesses saw the children on and near Glenelg Beach with a tall man who had fair to light-brown hair, a thin face, a sun-tanned skin tone, and a medium build. He was in his mid-thirties. The children were confirmed to have been seen at Colley Reserve and at Wenzel's cake shop on Moseley Street, Glenelg. Despite many searches, the children and the man were never found.

The case gained worldwide attention and influenced changes in Australian habits, as parents began to believe children could no longer be considered safe when left unsupervised in public. Police and media have connected the disappearances to the "Adelaide Oval abductions" of Joanne Ratcliffe and Kirste Gordon in 1973. Interest in the case has lasted for more than 50 years. As of 2018, the South Australian government offered a A$1 million reward for information related to the cold case.

Background

Jane, Arnna, and Grant Beaumont lived with their parents, Grant "Jim" Beaumont, who was a former serviceman and taxi driver, and Nancy Beaumont (née Ellis). The couple married in December 1955. The family lived at 109 Harding Street in Somerton Park, South Australia, a part of Adelaide. Their home was near Glenelg Beach, a popular place the children often visited. On 25 January 1966, during a summer heatwave, Jim took the children to Glenelg Beach and then left for a three-day sales trip to Snowtown.

On the morning of 26 January (Australia Day), the children asked their mother if they could go to Glenelg Beach again. It was too hot to walk, so they took a 3-kilometre (1.9-mile) bus ride that took five minutes from their home to the beach. They boarded the bus at 8:45 a.m. and were expected to return home on the 12:00 p.m. bus. Nancy became worried when the children did not return on the 12:00 p.m. or 2:00 p.m. buses. When Jim returned home early from his trip around 3:00 p.m., he immediately drove to the crowded beach. He could not find the children, so he returned home and both parents searched the streets and visited friends’ houses. Around 5:30 p.m., they went to the Glenelg police station to tell them about the missing children.

Police investigation

Police quickly set up a search of Glenelg Beach and nearby areas, believing the Beaumont children were close by and had lost track of time. The search later included the sandhills, ocean, and nearby buildings. Police also watched the airport, train tracks, and highways because they feared an accident or kidnapping. Within one day, the whole country knew about the case. Three days later, on January 29, a newspaper headline read "Sex crime now feared," showing growing worry that the children had been kidnapped and harmed by someone who committed sexual crimes. However, the official reward for information was only £250.

On January 29, the Patawalonga Boat Haven was drained after a woman told police she had spoken with three children who looked like the Beaumont children near the haven at 7:00 p.m. on the day they disappeared. Police cadets and emergency workers searched the area but found nothing.

Police found witnesses who saw the Beaumont children in Colley Reserve, near Glenelg Beach, with a tall man who had light brown hair, a thin face, and was in his mid-thirties. He had a tan and a thin or athletic build and wore swim trunks. The children played with him and seemed relaxed. The man asked a witness if anyone had touched their belongings, saying their money was "missing." He then left to change while the children waited. Later, the group was seen walking away from the beach around 12:15 p.m. About two and a half hours later, at 2:45 p.m., another witness, Miss Daphne Gregory, saw the children with the man, who was carrying a bag similar to one owned by Jane.

The Beaumont parents described their children, especially Jane, as shy. For them to be so comfortable with a stranger seemed unusual. Investigators thought the children might have met the man during earlier visits and had come to trust him. A comment from Arnna, who said Jane had "a boyfriend down the beach," was later considered important. Her mother, Nancy, initially thought it meant a playmate and did not investigate further until after the disappearance.

A shopkeeper at Wenzel's Bakery reported that Jane had bought pasties and a meat pie using a £1 note. Police saw this as evidence the children were with someone else. The shopkeeper knew the children well and said they had never bought a meat pie before. Also, the children’s mother had given them only six shillings and six pence, enough for their bus fare and lunch, not £1. Police believed the extra money came from someone else.

According to an early report, the Beaumont children were seen walking alone at 2:55 p.m. along Jetty Road, heading toward their home. A postman, who knew the children well, said they were holding hands and laughing in the main street. Police were puzzled because the children were already an hour late and seemed unconcerned. The postman later changed his story, saying he might have seen them in the morning instead of the afternoon.

Other sightings of the children were reported for about a year after they disappeared.

The Beaumont case gained international attention. On November 8, 1966, a Dutch psychic named Gerard Croiset was brought to Australia to help find the children. His work caused controversy in the press, but it did not lead to any useful clues. Croiset claimed the children’s bodies were buried in a warehouse near their home, inside the remains of an old brick kiln. Property owners hesitated to dig based only on his claim but agreed after public pressure raised £40,000 to demolish the building. No remains or evidence linked to the Beaumont family were found. In 1996, the building was partially demolished, and a full search was allowed. Again, no trace of the children was found.

About two years after the disappearance, the Beaumont parents received two letters. One was supposedly from Jane, and the other from a man who claimed he was keeping the children. The letters had a postmark from Dandenong, Victoria. They described a relatively happy life and mentioned "The Man" who was keeping them. Police believed the letters might be real after comparing them with Jane’s handwriting. The man’s letter said he had taken on the role of "guardian" and was willing to return the children. A meeting place was suggested.

The Beaumont parents, with a detective, went to the meeting spot, but no one appeared. Later, a third letter, supposedly from Jane, said the man had realized a detective was present and decided to keep the children because the Beaumonts had betrayed his trust. No more letters arrived. In 1992, new forensic tests showed the letters were a hoax. Improved fingerprint technology identified the author as a 41-year-old man who had been a teenager when he wrote the letters. Because so much time had passed, he was not charged with any crime.

Possible suspects

Bevan Spencer von Einem (1946–2025) was sentenced to life in prison in 1984 for killing Richard Kelvin, the teenage son of Adelaide newsreader Rob Kelvin. Police and prosecutors said they believed von Einem had helpers and may have been involved in other murders. Around the same time, police began to suspect von Einem might be connected to the Beaumont disappearance, as he looked like descriptions of the unknown suspect from 1966. No helpers were ever charged, and von Einem refused to help investigators with other possible crimes.

During the investigation, police spoke with an informant known only as "Mr. B." Mr. B said he overheard von Einem claim he had taken three children from a beach years earlier and brought them home for "experiments." He said von Einem performed "surgery" on the children and connected them to machines. One child died during the procedure, and the other two were killed and buried in bushland near Adelaide. Mr. B also said von Einem admitted to being involved in the Adelaide Oval abductions from 1973.

Detective Bob O'Brien said Mr. B had provided useful information about the Kelvin murder and was considered reliable. However, some details from Mr. B’s story did not match facts about the Beaumont case and were doubted. As of 2014, von Einem was still considered a suspect.

Mr. B’s claim about surgery matched reports from coroners about some of von Einem’s victims. However, von Einem was younger than the unknown suspect (who was in his mid- to late 30s) and was not in Adelaide during the Beaumont disappearance. The Beaumont children were also much younger than Richard Kelvin or other victims von Einem is believed to have targeted. These differences in how a killer acts are rare but not impossible.

Investigations into the Beaumont disappearance and the Adelaide Oval abductions are still open. In 1989, von Einem was named a suspect in a secret police report. In 2007, police reviewed old footage from the Beaumont search and found a young man who looked like von Einem. They asked the public to help identify him.

Arthur Stanley Brown (1912–2002) was charged in 1998 with killing sisters Judith and Susan Mackay in Townsville, Queensland. The girls disappeared on their way to school in 1970 and were found dead days later. Brown’s trial was delayed in 2000 because his lawyer argued he was too sick to be tried. Brown was found to have dementia and Alzheimer’s disease and was not retried. He died in 2002.

Brown looked like the suspect in both the Beaumont and Oval cases. However, no records showed where he was in 1966, and some documents were lost in a flood. Brown may have destroyed his own files. A witness said Brown mentioned seeing the Adelaide Festival Centre being built, which would place him in Adelaide around the time of the Oval abduction. However, no evidence links him to Adelaide in 1966. Brown was 53 when the Beaumont children disappeared, which does not match the suspect’s age of being in his 30s.

James O’Neill (born 1947) was sentenced to life in prison for killing a 9-year-old boy in Tasmania in 1975. He told others he was responsible for the Beaumont disappearance. In 2006, O’Neill tried to stop a documentary from showing evidence linking him to the case but lost the legal battle.

Detective Gordon Davie spent three years talking to O’Neill to gain his trust for the documentary. Davie said there was no proof linking O’Neill to the Beaumont case but believed he was involved. O’Neill said he was in Melbourne at the time of the disappearance, but Davie thought this was not a clear denial. O’Neill worked in the opal industry and often visited Coober Pedy, which is near Adelaide. Davie also suspected O’Neill was involved in the Adelaide Oval abductions. Police later ruled him out as a suspect.

Derek Percy (1948–2013), a man who was convicted of killing a child and spent many years in prison, was suggested as a suspect in the Beaumont case in a 2007 article. The article said evidence pointed to Percy in several unsolved child murders. Percy claimed he had a mental condition that made him forget details of his crimes. He said he might have been near the Beaumont children but had no memory of killing them. Police asked to question him about the case in 2007.

Percy was 17 in 1966, which was too young to be the suspect seen with the children. It is also unclear if he had a car at the time, which the suspect is believed to have had. Percy was in prison from 1969 until his death in 2013, so he could not have been the suspect in the Adelaide Oval abductions.

Alan Maxwell McIntyre, who was cleared of involvement in the Beaumont case, told the Adelaide Advertiser that a man he knew in 1966 had brought the children’s bodies to his home. McIntyre’s children said they thought one of the bodies was a boy because the child had a short haircut. The man was later identified as Alan Anthony Munro, a businessman who was 75 in 2017. At that time, Munro was being sought in Southeast Asia for child abuse cases.

Legacy

The Beaumont case led to one of the largest police investigations in Australian history and is still considered one of Australia's most well-known unsolved cases, even after many years. In January 2018, the Premier of South Australia, Jay Weatherill, stated that South Australia Police had "never given up on the case" and that they "have a policy that no murder investigation ends up in a closed file." The State Government continues to offer a A$1 million reward for information about the children's disappearance.

The kidnapping is seen by many experts as an important moment in how Australian society changed, as many people began to supervise their children more carefully. At the time, it was not suggested that the children should not have traveled alone or that their parents were careless, because it was widely believed that this was safe. However, this case, along with similar events like the 1960 Graeme Thorne kidnapping and the 1965 Wanda Beach murders, marked the end of a period of innocence in Australian life after World War II.

The Beaumont case has received regular attention from the media over many years. It is important in Australian criminal history, and the mystery of the children's disappearance has never been solved. Because of this, the story is often covered in newspapers and on television, even more than 50 years after the event.

During the investigation, the Beaumont parents received a lot of public support. They stayed in their home in Somerton Park, and Nancy hoped the children would return. She said in interviews that it would be "dreadful" if the children came back and found their parents not there. Over the years, as new ideas and clues appeared, the Beaumonts worked with investigators to explore all possibilities, including claims that the children were taken by a religious group and lived in places like New Zealand, Melbourne, or Tasmania, or that clues pointed to possible burial sites. In 1990, they were deeply upset when newspapers published computer-generated images of how the children might have looked as adults. These pictures, shared without their permission, caused strong public support for the family.

Later, the Beaumonts divorced and lived separately, choosing to spend their later years away from the public attention that followed them for many years. They sold their home in Somerton Park, and the South Australian Police kept track of their new addresses because the case is still open. The Beaumonts accepted that the truth about their children's disappearance might never be found. Nancy passed away in an Adelaide nursing home on September 16, 2019, at the age of 92. Grant died in Adelaide on April 9, 2023, at the age of 97.

Media

The case received a lot of attention from police and news organizations in Australia and other countries. Because the case has never been explained, the story has been discussed again and again by the media and websites on the internet, more than sixty years after the children disappeared. Some examples include:
