South Australia 1973 Cold Case FINALLY Solved — The Arrest That Shocked the Entire Community

There’s been a dramatic development in a 45-year-old cold case. 70-year-old Jeff Adams, the husband of Colleen Adams, who was last seen in November 1973 on York Peninsula, has now been charged by police with her murder.  On the afternoon  of the 18th of September, 2018, a reporter from 9 News Adelaide stood at the front door of a 70-year-old man in Wallaroo, South Australia, and asked whether he had killed his wife.

The husband said no, flatly. When told  police had named him as a suspect, he shrugged. “All husbands are a suspect,” he said. “Yeah, he believed his wife was probably still alive somewhere. He hoped she was well.” His wife had been missing for 45 years. Their two daughters, 3 and 18 months at the time, had been asleep in the next room the night she vanished.

 They had grown up since, raised by the man  at that door. He had been the obvious suspect, but police had never found a body. By the next morning,  all of that would change. The 18-month-old who had slept through it was 46 years old. This is how everything changed after almost five decades. On the night of the 22nd of November, 1973, the 25-year-old husband came home late and drunk to a house  on Bagnal Avenue in Maitland, a small town on South Australia’s  York Peninsula. His wife was waiting up, and

an argument started the moment he walked through the door. According to what he would later tell police, she had been on at him for weeks, continuously having a go at him over nothing, he said, yelling and screaming. It had gone on for too long. What happened next took seconds. He picked up a metal bar and struck her across the head. He hit her again.

She collapsed onto the kitchen floor and did not get up. The house had four people in it that night. The husband upright in the kitchen, his wife on the floor, and in a bedroom down the hall, two little girls asleep. Marie was 3 years old and Kay was 18 months. Neither would remember a thing. The husband did not call an ambulance.

He did not call a neighbor, a relative, or anyone else. He left her where she lay and went somewhere else in the house. For the rest of that night, while his daughters slept down the hall, her body stayed on the kitchen floor. He stayed in the house until morning. When daylight came, he went into the backyard with a shovel and started digging.

The grave he dug  was shallow, just deep enough to hide what was going in it. When the hole was ready, he carried his 24-year-old wife outside,  lowered her into the ground, and covered her over. By the time his daughters woke up that morning, the only physical evidence of what had happened in their kitchen the night before was already underground.

He cleaned the kitchen and made the girls something to eat at the same table where their mother had died. At some point that day or in the days that followed, he poured a concrete slab over the patch of disturbed soil in the backyard. The exact timing was never clear. Possibly within hours, possibly weeks. What was clear was the result.

A flat patch of concrete behind the garden shed, nothing anyone would think to look beneath. Even years later, when detectives stood in  that backyard wondering where to dig, the slab read as ordinary. The next morning, in a kitchen with no body on the floor and a fresh patch of dirt outside, the husband sat down and worked out what to  say.

The story he came up with was specific enough to be plausible. He told everyone, neighbors, family, police, that he had woken up at 7:00 a.m. on the 22nd of November to find his wife fully dressed at the bedroom door. Two suitcases beside her, packed and ready. She told him the marriage was over, that she never  wanted to see him or their two young daughters again.

He said he walked out behind her and watched her climb into a car waiting in the street. A middle-aged woman he had never seen before was behind the wheel. The car drove off and his wife  was gone. In a country town in 1973, a woman walking out on her family was a story. It was unusual and it was a scandal, but it was not a crime.

People talked  about it for weeks and then they stopped talking about it. The husband added details over time. He told police his wife had been suffering from post-natal depression. And he claimed  that on the way out the door she had paused to say goodbye to their daughters by calling them little bastards.

Piece by piece, he built the picture of a mother so broken and so heartless that abandoning two toddlers  fit who she really was. The lie was about her, not him. Colleen Adams had been born in 1949 in Wallaroo, a coastal  town on the York Peninsula. Her mother was Vera Milbank. Vera waited 27 days.

 She was hoping for a letter or a phone call. Her daughter would surface somewhere, send word that she was alive and that the story her husband was telling was at least partly true. For 27 days, nothing came. On the 19th of December, 1973, Vera went  to the police and filed a missing person report. She told officers her daughter would not have left without a word.

She said Colleen loved those children. Police wrote down the reason for the disappearance as domestic conflict,    destination unknown. Officers drove out to Bagnall Avenue and interviewed the husband who gave them the same story he had given the family. They walked through the house and saw no blood, no damage, nothing to suggest violence had taken place inside those walls.

The case went into the system as a voluntary disappearance.  It would stay that way for 45 years. Subscribe so you don’t miss what finally changed that. For 5 years, that classification stayed in place. Her file sat in the missing person section of the South Australia Police archive.  The years passed and she never resurfaced.

No letter to Vera, no call to her sisters Heather and Christina, no contact with friends. The bank accounts she had shared with her husband sat untouched. She made no attempt to see her daughters, not once. The family did not let it go. Heather, who had been 16 when her sister disappeared, kept telling police the story did not add up.

 The sister she had grown up with was not capable of leaving those children. Something else had happened, but belief is not evidence. Without something to contradict the husband, the file stayed where it was. By 1979, the silence had become the evidence. Six years with no contact,  no word, no sign of life pointed to one explanation, and it was not the one the husband had given.

South Australia police reclassified the disappearance as a major crime. Detectives interviewed him again. He was calm, consistent, and cooperative  as ever. Six years had not put a single crack in him. The problem for the investigators was that they had nothing to work with. Without a body, there was no cause of death.

Without a cause of death, no charge to bring. Without a witness, no corroboration. Suspicion was not enough. And belief does not stand up in court. Evidence does. And there was  none. The 1980s passed. And the case ground forward with nothing to show for it. Tips came in occasionally. A rumor about the night of the 22nd of November would surface and then evaporate.

 Detectives followed each lead and watched it collapse. The file moved between offices. Each generation inheriting the same notes and the same dead ends. By the 1990s, nothing had changed. The husband was still  on the York Peninsula. Still raising the two daughters whose mother he had killed in their kitchen. He moved from Maitland to Wallaroo at some point, about 20 minutes down the road.

 The same town his wife had been born in. In 2001, detectives took another run at it on the theory that the remains might have been disposed of away from the family property. A search was organized at a local rubbish tip. And officers worked  through the site over several days and found nothing. A $200,000 reward was posted by the  South Australian government for information leading to the recovery of the remains or the conviction of the person responsible.

Nobody could claim it. The only person who knew where Colleen was had retired in Wallaroo. The slab in the Maitland backyard  stayed where it was. Marie and Kay grew up in that house. The older girl was old enough to carry fragments. The younger one was too young to remember anything. Whatever they knew about Colleen came from their father.

 And what their father told them was the version he had constructed in November 1973. Kay had no memory of her mother. Not a face. Not a voice. Not a moment. The mother she grew up understanding was the woman in her father’s story. A stranger who had decided one morning that she did not want to be a mother and walked out the door. Marie carried that same picture into adulthood.

She believed for most of her life that her mother had left because of her. That a mother walking away from a 3-year-old and an 18-month-old without ever looking back meant something had been wrong with the children. Both girls grew up in Maitland and went to school there. They built their own lives on the same stretch of peninsula coastline where they had been born.

Everyone in that town knew the story. People knew Marie as the daughter of the woman who left. The mother she was grieving was a woman she had been taught to feel ashamed of. Heather pushed. She told them again and again that their mother had loved them. That she would not have walked out. But Heather had no proof.

The story was the story.    And the story came from their father. And their father lived in the house. Heather and Christina did not stop. They wrote letters, followed up with detectives, talked to journalists. They named the man they suspected to anyone who would listen. For 45  years, his version and theirs stood side by side in the same small town.

Only one of them was true. The truth about Colleen sat under a concrete slab behind their father’s garden shed. In September 2018, the case was 45 years old. South Australia police had a cold case review process for unsolved major crime files, and Colleen Adams was overdue for another look. On the 16th of September 2018,  the Major Crime Investigation Branch opened the file from the beginning.

Two days later, on the 18th of September 2018, a team of detectives arrived at the property on Bagnal Avenue. The husband still owned the house and was renting it out. Police needed his permission to search it, and he gave it. They brought ground-penetrating  radar and specialist camera equipment. Over two days, they scanned the backyard and the inside of the house.

They identified what Detective Superintendent Des Bray called an anomaly, an area beneath one of the concrete slabs where the soil did not match the rest.  The detectives dug it up, found nothing yet, and kept looking. While the dig was going on, Detective Michael Newbury spoke to reporters. “We have an open mind as to what has happened and how it has happened,” he said.

 “But we are of the opinion Colleen has been murdered.” On the afternoon of the 18th of September, Bray held a media briefing. He confirmed police had spoken with a suspect and searched the Maitland  property, but no remains had been found yet. “The family of Colleen Adams deserved answers,” he said,    “and the investigation would not stop until they got them.

He did not name the suspect. He did not need to. Anyone who had followed the case for 45 years knew who had lived in that house in 1973. That same afternoon, a reporter from 9 News Adelaide drove up the peninsula  to Wallaroo and knocked on the door of the 70-year-old husband. The footage of the conversation that followed is brief.

 A 70-year-old man in his doorway, a reporter on the path, a camera between them. The man denied killing his wife. When told police had named him as a suspect, he shrugged. He gave the line that led the news that night and ran on bulletins  the next morning. The rest of his answers came from that doorway, 30 km up the road  from the backyard where his wife was buried under a slab he had poured 45 years earlier.

It was the last time he told us. The next morning,  the 19th of September, 2018, detectives drove back to Wallaroo. The 18th of September evening news had carried both Bray’s briefing and the doorstep clip. They sat down with the 70-year-old  at his kitchen table. And for the first time in 45 years, he told them what had really happened on the night of the 22nd of November, 1973.

He said he would come clean. He said he had been carrying it since the morning he buried her and it was time to talk about it. The interview that followed ran for more than 2 hours, all of it on video, all of it played later in court. His name was Jeffrey Gordon Adams. Adams  gave them the full account.

 “I just struck her a bit hard and that was it,” he told  the detectives. “She fell to the floor and then she died.” He said his two daughters had always had a suspicion, though he had never admitted anything to them. He said the police had come close to finding her once, 15 years earlier, though he did not elaborate on what he meant.

Then, he told them  where to look, the backyard of the Maitland house, beneath the concrete slab behind the garden shed. He offered to take them there. That afternoon, Adams accompanied detectives back to Bagnall Avenue and stood in the backyard where he had dug the hole in November 1973. He pointed out where to look.

 Standing on the slab he had poured, he said sorry.  He was arrested there and charged with murder. He did not apply for bail. The following morning, he appeared by video link at Kadina Magistrates Court and was remanded at Port Pirie Prison. Officers from the South Australia Police Major Crime Investigation Branch brought excavation equipment to Bagnall Avenue that afternoon.

They cordoned the backyard with crime scene tape and set up a tent over the slab Adams had identified. Forensic anthropologists worked through the night to prepare. The dig started at first light on the  20th of September. The slab came up first, then the soil beneath, one layer at a time. Just after 1:00 p.m.

, they found her skeletal remains at a depth consistent with a hand-dug grave from 1973, beneath the concrete  Adams had poured, 45 years in the ground. “She was in the area indicated to us,” Bray told reporters, “discovered about 1 hour ago. Forensic examination of the remains confirmed what Adams had described in his confession.

The pathologist found multiple fractures to the skull consistent with repeated blunt force trauma from a heavy metal object. There was also a broken hand, an injury consistent with raising an arm to block a blow. Some of the bones had been damaged in the excavation process, but the original injury pattern was clear.

A short time later, Kay arrived at the scene. She had not been back to the property since she was a child. She had been 18 months old when her mother was buried and was 46 now. Kay handed a statement to victim contact officer Debbie Gibson who read it out to the media on her behalf. “Today I finally found my mother.

” The statement said. “After 45 years of hoping, we have found her.” She thanked the South Australia police. She said  she wanted the day to be one of inspiration to anyone living with a cold case. “Today we have seen there is hope.” Colleen’s remains were taken for formal identification and forensic examination at Forensic Science SA.

 Adams offered a plea to manslaughter. He admitted to killing his wife, to burying her in the backyard, to lying about it for 45 years. The Crown did not accept the plea. Chief Crown Prosecutor Jim Pears, KC, pushed the case to trial on a charge of murder. The trial opened in the Supreme Court of South Australia on the 10th of August 2020  before Justice David Peak.

Pears told the jury that decades of calculated deception pointed to a man who had acted with clear intent. “He spent 45 years peddling a story to police and the media.”  Pears said. “He spent 45 years creating a false narrative of a mentally unstable woman who abandoned her children. The slab itself was evidence.

A man who killed in a moment of rage did not pour concrete days later. The cover-up had been planned. The jury watched the video of the confession. The 2-hour recording was one of 11 hours of police interviews Adams gave in custody. What Magistrate Elizabeth Sheppard had described at committal as  the core piece of evidence.

Adams was 72 by the time the trial opened and sat in the dock crying as the footage played. He did not give evidence in his own defense. Defense counsel Bill Boucaut QC accepted everything except intent. The killing, the burial, the decades of lying, none of that was contested. But the despicable lies did not prove murderous intent at the moment of the killing.

 The blows happened in a domestic argument, not as part of a premeditated attack. Adams may have lashed out, realized what he had done, panicked, and committed to the cover-up that followed.  That was manslaughter followed by concealment, not murder. The jury deliberated and  returned on Friday, the 21st of August, 2020, not guilty of murder, guilty of manslaughter.

 The Crown had pushed for the higher charge and lost. But manslaughter still carried a maximum of life imprisonment in South  Australia. The family had waited 47 years for a trial. They expected to hear the punishment read out. The sentencing submissions were held the following month. Marie Colleen Adams gave a victim impact statement to the court.

She had been just 3 years  old when her mother was killed. She was 50 now, and she had carried her mother’s name as her middle name through every year of her life without ever knowing who her mother actually was. “I believed that I had been responsible for her leaving.” she told the court. “I thought that I must be unlovable.

” She said everyone in town had known the story of her mother going missing. The fact that it was one of those untold stories of the town hung over her head as she grew  up. She said she had felt rejected and like she did not belong. “I felt like I was living with the sins of my mother.” she said. “And now I realize it was the sins of my father.

” She said the most meaningful moment from all of it had been knowing that her mother had loved her. That her mother had not chosen to abandon her. That the picture she had carried for 47 years was a lie her father had constructed and maintained. “Not only have I lost my mother.” she told the court.

 “But I feel that I have also lost my father.” Buik Co, in his sentencing submissions,    told the court that Adams had eventually offered a measure of cooperation. “Even a belated confession is better than no confession.” he said. Adams was sent to prison after the verdict to await sentencing. He had been behind bars since his arrest in September 2018.

 A little over 2 years. The sentencing was scheduled for late 2020.  It never happened. In early December, the Supreme Court received  medical reports from Royal Adelaide Hospital. Consultant  physician Dr. Patrick Russell informed the court that Adams had been diagnosed with glioblastoma multiforme, an aggressive brain cancer.

The disease was advanced and inoperable. His neurological deficit has taken a steep change for the worse. Dr. Russell wrote on the 10th of December. Now completely paralyzed on the left, unable to open that eye or move his arm or leg. On his current trajectory, he was expected to die within weeks, likely in hospital.

On the 14th of December 2020, Justice Peak convened a hearing to address the situation. Adams was not in the courtroom. Buikol told the court  his client had taken a turn for the worse on the Friday morning and was not expected to last the weekend.  He was alive but unconscious and in a state which is clearly near death.

The sentencing was adjourned until the following April. The date never came. Adams died overnight in his hospital bed at the age of 72. Heather Johncock had the final word. In the end, we got to the bottom of what happened, she said. We got through the trial and he had to tell the truth and now this is the end of it.

The important thing is that we got Colleen back, a 24-year-old mother in a shallow grave for 45 years. Two daughters in the same small town for the same length of time told their mother had walked out on them. A husband 20 minutes down the road who stuck to the story until the morning he sat at his kitchen table and finally told the truth.

He died in custody with a manslaughter conviction on his record and not a day of a sentence served. Colleen had been dead for 47 years. The slab behind the garden shed is gone now. If this case stayed with you, leave your thoughts in the  comments. More solved cases in the playlist.
