Key Discussion Points & Insights

The Crimes & Suspicions Surrounding Dieter Fenwick

• Dieter Fenwick was convicted for the murder of Michael Black and later Louise Bell, with additional suspicions regarding other missing children in South Australia.
• There was initially a wrongful conviction in the Louise Bell case before Fenwick's connection was proven.
• Madigan notes the possibility Fenwick was involved in multiple unsolved child cases:

  "You can almost say that Dieter might have been involved with every one of them. I mean, how many serial killers of children are there in South Australia?"
  — Michael Madigan (D), [01:51]

The Disappearance of Louise Bell (January 1983)

• Louise and her sister Rachel were last seen happy at home the night before Louise vanished.
• The next morning, Louise's mother discovered her gone, a piece of window screen torn away, and panic ensued.
• Police mounted a large search; the case deeply unsettled the neighborhood.

  "You can imagine the fear involved with finding your child missing from your home."
  — Michael Madigan (D), [02:33]

• Extraordinary clue:
  • Neighbor Mrs. S received several mysterious phone calls from a man with a German accent claiming to be Louise's abductor, requesting medical help and revealing details only the culprit could have known.
  • This caller directed police to buried earrings, which proved authentic, linking the caller directly to the crime.

  "He explained what happened, as in the screen. And he also said that if you tell the police to look under a rock ... you'll find Louise's earrings."
  — Michael Madigan (D), [04:09]

  • Shortly afterward, Louise’s clothing was found folded on Mrs. S’s lawn, evidence that the perpetrator was psychologically manipulating both police and those around the family.

The Kidnapping and Death of Michael Black (January 1989)

• Michael Black, 10, set out to fish on his own for the first time and never returned.
• His belongings were later found neatly stacked on the forbidden side of the bridge—a significant detail given Michael’s usual behavior.

  "Michael’s a notorious untidy young boy like every 10-year-old boys are and he would never leave his stuff neatly in a, in a little neatly pile."
  — Michael Madigan (D), [07:21]

• Witnesses saw Michael with a man near a Combi van, and a local noticed suspicious behavior from a similar vehicle.
• The police worked timelines, gathered witness statements, and tracked other instances involving a combi van and potential attempts at abduction.

The Abduction and Escape of Robert: Linking Fenwick to the Crimes

• In December 1989, Dieter Fenwick abducted another young boy (Robert) by luring him with help to retrieve ‘lost keys,’ then gagging, confining, and sexually assaulting him.
• Fenwick showed meticulous efforts to remove forensic evidence, mirroring the calculated, ritualistic aspects of previous crimes.
• Robert displayed remarkable courage in escaping, freeing himself from his bonds while Fenwick was out buying cigarettes:

  "He started to wriggle his little fingers in and out of the, the knots... all of a sudden it came free...he climbed up on the sink, pulled aside the glass part of it and kicked in the screen, jumped out and goes to the neighbour."
  — Michael Madigan (D), [14:56]

• When confronted by police, Fenwick responded evasively, even stating his name as “mud”:

  "The police ask him, you know, we found this little boy in your home, what's your story? And he said, oh, it was just that I need someone to hug ... And Fennec said, mud. And that was probably the truest thing he's ever said."
  — Michael Madigan (D), [14:56]

Evidence and Conviction

• The prosecution tied Robert’s abduction to Michael Black’s case, highlighting the overwhelming probability that the same predator operated each time.

  "The judge said, what are the chances that two child abductors was at Murray Bridge at the same time talking to Michael Blight?" — Michael Madigan (D), [14:56]

• A planted pajama top, ignored for decades, was linked to Fenwick via advanced DNA technology in 2013.
  • At trial in 2016:

  "The prosecutor came out on day one, said it was a billion to one chance that it wasn't Dieter Fennick." — Michael Madigan (D), [17:47]

• Despite conviction, Fenwick never assisted with the recovery of the victims’ remains and continued to deny guilt publicly, while reportedly making confessions to other inmates.

Lingering Trauma and Unanswered Questions

• Police and families remain haunted by Fenwick’s refusal to reveal what became of the children.

  "I talked to one of the leading detectives... he used to visit Fenwick quite often just to ask one question. Can you tell us where the bodies are? ... But Fennec denies that he's even guilty." — Michael Madigan (D), [18:37]

Transcript

[A]

The following podcast contains accounts of child sexual assault. Listener discretion is advised.

[B]

I'm doing time for something I haven't done because as you were probably aware, I was convicted of the murder, kidnapping, murder of Michael Black and I still don't know how I got convicted for something I haven't done. I don't even understand what happened there.

[A]

At the time of that police interview, former South Australian teacher Dieter Fenwick was serving time for the abduction and murder of one child, 10 year old Michael Black, and for the abduction and rape of another. Police interviewing him suspected he was responsible for the disappearance and murder of a third child, 10 year old Louise Bell. He was eventually convicted of that crime too, but not before an innocent man was accused and convicted. Michael Madigan has written an excellent book about the case called Father Teacher Child Killer, which takes us into the crimes and the investigations. It also asks if there are links to other notorious and unsolved crimes against children. This is Australian true crime. We acknowledge the traditional owners of the land on which this podcast is created, the Wurundjeri Woi Wurrung People of the Kulin Nation.

[D]

Sometimes South Australian stories are a little bit forgotten, but look, there's a whole heap of stories that if you, if you really look into it, they are almost. Well, I put at the end of the book that you can almost say that Dieter might have been involved with every one of them. I mean, how many serial killers of children are there in South Australia?

[A]

And we are talking about a sort of cluster of missing and murdered children in Australia over the summer months, over the period of a couple of decades. We all know the story of the Beaumont children, but Louise Bell, January 1983.

[D]

Little Louise back in January 1983, the night before, the two little girls, Rachel and Louise, were dancing in their room with their new cassette player. The neighbors over the road could see how happy they were. They just had Christmas and they were looking forward to going to watch the movie E.T. the next day. So it was a wholesome household. But that night, when the parents went to bed in the morning, Mrs. Bell woke up and checked the girls and Found that Louise was missing and there was a piece of torn screen missing from the window and she ran up the street and looking for her, but she eventually got back to her husband and they both looked and they like, yeah, you can imagine the fear involved with finding your child missing from your home. So, yes, the police did a massive search and nothing was found of Louise that day. The crime really rocked the neighbourhood.

[A]

Tell us about the neighbour who received the phone calls. This is an extraordinary development in the investigation, isn't it? A neighbour of the Bell family, Louise Bell's family, becomes enmeshed in this story and this crime.

[D]

Well, that's right. We'll. We'll call this neighbour, Ms. S. Mrs. S. She was just watching television one night and the phone rang and on the phone, this person with a slight German accent started to tell her that he wanted medical information to help Louise Bell. Louise Bell was injured and he was the abductor, which was an incredible thing for her to take in all at once. But then she said, well, how do I know that you did it? And he explained what happened, as in the screen. And he also said that if you tell the police to look under a rock on the corner of south roads and Dr. Road, you'll find Louise's earrings. And she couldn't believe it. And he explained to her the extent of Louise injuries and she was shot. And so she rang the police and the police went over to the location and they found these earrings and they took it over to Mr. Bill to identify. And he. He looked at them and saw a little scratch where his he had repaired. And so it proved that this abductor on the phone was in fact the murderer of Louise. Probably four, five weeks later, Mrs. S, the neighbor, was walking her son to school and she noticed a bit of clothing on her lawn, neatly folded. And then she remembered a bit of the publicity of what Louise was wearing. So she rang up the detectives of the case and she said, you wouldn't believe what I've just found on my front lawn. And they raced to her and yes, it was Louise Bell's top. So this guy was playing all sorts of mind games with police. So the forensics went through it thoroughly, did a fantastic job, mind you, and they tracked down that this could only have happened. This could only have been in the waters off of Onkaparinga water, which is not far away from the Bell household. So they had something to look for. So they sent divers into the river. It was a part of the river that this special algae and sand was around. So they spent a few weeks diving and searching but nothing was found.

[A]

So Louise bell disappears in 1983, in January. We go forward then to January 1989 and another 10 year old Michael Black. What can you tell us about the Michael Black story?

[D]

Yeah, well Michael Black grew up in Murray Bridge which is about 75km from Adelaide. It sits on the Murray river and Michael and his dad normally go fishing together. But it was his dad's first day back at work and his mother was working as well. They were separated at the time. And so this is a big day for Michael. This is the first day that he was to go on his push bike down to the river to do some fishing. And before he went down Mr. Black told Michael that you know, you must be stay where we always fish which is on the side, the Murray Bridge side of the bridge. Do not go over the bridge because it's very dangerous with all the trucks and the cars crossing, you know. He was only 10 years old but he was a very competent young boy. He left about 1:30 on, on that day and at 4:30 Mr. Black thought oh, Michael should be home by now. So he went looking for him in his car and when he got there he, he looked at the, the normal place that they fished and he wasn't there. He ran along and saw a few people and described Michael and then he started to panic. This is not like Michael. So he thought oh perhaps I've missed him on the way here. So he drove around the town becoming more and more anxious. Obviously Michael was a very obedient boy. After searching for an hour or so he, he contacted, rang the police, he said look this is not like Michael. He, he, I want you to you know, go and send a unit out there to help for search along the river. So the police did that. About 7 o' clock he received a phone call from the police saying that they found Michael's belongings, his bite fishing gear, T shirt over the other side of the bridge and they were in a neat pile and David knew exactly then that something more sinister was happening. Michael would never disobey his instructions. And Michael's a notorious untidy young boy like every 10 year old boys are and he would never leave his stuff neatly in a, in a little neatly pile. So the theory was that Michael did drown but the local police officer was put in charge of gathering more information. And so with his hard work he started to put together a timeline of Michael. He was seen at the shop at 2:30. He was seen with a person next to a combi van at 2:45. And then they had other reports the day before of a person in a combi van asking strange questions. He asked a local where there was a beach that you could swim nude in. And that was a bit disturbing. And then two children, two lucky children told the police that they were. There was a person that they played together in the water and this person, this man invited them over to his combi van but they declined. So there's this sort of a picture building up and then there was a lady who didn't see anything but heard something. She was on the other side of the bridge. She had a two story house and she heard a commotion where Michael's things were found. She heard a barking of a dog and a van like vehicle drive away at a rapid pace. Later, in 1989, 30 December 1989, a young, a young boy from Port Malunga, not far from Hackam west, he had borrowed his friend's bike and was taking it for a ride. It's a little bit hilly, so he's coming down this road at a rapid pace and almost hit this person, this man standing next to a combi van. He put his bike up against the deli and the man across the road said, hey, can you help me please? I've dropped my keys down this slot, I can't. He held up his hands, my hands are too big, could you come and help me? And the boy looked a little bit. He remembered his mum telling him, you know, beware of strangers. And he was about to go into the deli and this person, man said with a very loud voice, please come over here now, come and help me. And he opened up the side door of a van for the boy to help. And within a second this man had grabbed him, gagged him, tied his arms, went and got his bite and put that into the back of the van and drove off. The little boy was in shock. He was crying out for his mum and dad. This we'll call him. Well, who he is, he's Dieter Fenwick. Took the boy on a ride along the coast. They went up to a cliff where he took the boy's bike out and placed it next to some bushes. He wiped down the bike as if he was, you know, meticulous in trying to wipe out any sort of fingerprints or whatever. Nighttime eventually came and he shoved this little boy into a sleeping bag, carried him inside, stripped him naked, tied him up to a chair and fed him boiled carrots, you know. So this little boy, this brave little Boy, I don't know how he would have felt, but he would have been absolutely beside himself. Then Fennec takes him into the bathroom and bathes him like a little baby, like some sort of ritual. And then he gives the boy an option of being tied up all night or taking four sleeping tablets. The boy thought about the tablets, but he might not wake up. So he said, I'll be tied up. But the Fennec shoved down the tablets down his throat and in the morning again he tied him up on to a chair in the room. And because Fennec was a, a, a nicotine addict, he, he smoked profusely. So he went to get some cigarettes.

[A]

Ran out of smokes, basically.

[D]

He ran out of smokes. Yeah, this little boy had courage and, and had a will to, to live. He knew, he knew that Fennec is not going to back off. And so he started to wriggle his little fingers in and out of the, the knots and getting nowhere, crying. But something moved in the knot which gave him hope and he kept on digging his little fingers in and out and all of a sudden it came free. And so he undid his ankles which were tied up and he went to the front door, but that was locked, back door was locked. He saw the kitchen window and he climbed up on the sink, pulled aside the glass part of it and kicked in the screen, jumped out and goes to the neighbour. The neighbour wraps him in a rug and calls police. Fenwick eventually comes home. Police surround him. Fennec decides just to light up a cigarette. And the police ask him, you know, we found this little boy in your home, what's your story? And he said, oh, it was just that I need someone to hug. And then, then the officer asked him, you know, what's your name? And Fennec said, mud. And that was probably the truest thing he's ever said. The judge agreed with the prosecution that the case with young Robert, his abduction and sexual assault could be brought up on the case of Michael Black. So they charged Fennec with the murder of Michael Black, which was only about 12 months, well, not 11 months difference. And so they, they had a court case and in the end there was too much evidence. You know, the judge said, what are the chances that two child abductors was at Murray Bridge at the same time talking to Michael Blight? So he, he was found guilty and sentenced to a 25 year prison sentence. They, they didn't have to be brain surgeons to connect it to Louise Bell because he lived 10 minutes away from Louise Bell. So they started to dig up his home backyard in 1992 or three found nothing. So the case went dormant until 2013. But what really undid Fenwick was the pajama top that he planted on the neighbors. So when he planted that top in 1983, DNA was never heard of. In 2013, they charged him. They got a group of witnesses together. In 2016, the court case started. But the court case was dominated by the DNA. The prosecutor came out on day one, said it was a billion to one chance that it wasn't Dieter Fennick. That's, that's how strong they believe the case was.

[A]

So he never ever assisted in finding the remains of these children, did he?

[D]

No. I, I talked to one of the leading detectives in the Louise Bell and the Michael Black case and he used to visit Fenwick quite often just to ask one question. Can you tell us where the bodies are? The remains are. But Fennec denies that he's even guilty. So until he admits the guilt, although he has in jail admitted to other prisoners that he responsible. But I don't think he will ever give up where the bodies are.
