It would be interesting to see if the Glenelg and Henley Sailing Clubs still have records/history from 1966. I wonder if they still have old visitors books? I know for certain that Henley required sign-ins for non-members in 1966, and addresses too if you wanted a drink. You had to be recommended by a full member either way.

But l guess the police have thought of that lead long ago, or maybe not? No-one was looking for it at the time. If the name Percy is in any of those books in that time frame, we have our man and the case should be closed.

Newbie 11, l put some transport theories in post #4455 but l didn't think of trams.

Hi fellow sleuths! Longtime watcher, first time poster!

I've found the forum interesting, with a lot of different theories and possible POI's. In the end we are all guessing aren't we.

For people looking towards Percy, I do not believe Percy is the POI. I believe police had backtracked through his movements thoroughly and have clearly stated that he is not a POI in the BC case. I have been told the reason that is, is because they backtracked thoroughly. His height, description doesn't match to what has been described in the BC case. 5'10 surfie looking man, most certainly does not describe Percy.

Percy was about opportunity. The BC case was pre-meditated. It's too organised, for Percy. We have descriptions from witnesses that suggests prior contact with the POI. They were comfortable around this person/s. Percy, without a doubt looked like a psychopath from very early on. I do not believe that the children would have felt 'safe' with him and would not have left with him.

If they did leave with Percy - we would have many more sightings from witnesses - such as 'I was on the tram with these children, I saw them on a bus...' we have no confirmed sightings from witnesses other than what happened at the beach/bakery etc'.

Percy, held trophies. His writings were a mix between fantasy and truth. He was extremely intelligent held in high regard as a good student 'who achieved good results with very little effort' and also finished top of his classes in the Navy training (Feb 1968). Very intelligent.

Percy played his cards perfectly, declared 'Insane" and un-fit to stand to be prosecuted. Sometimes I wonder if Percy actually got himself locked-up because it was the only way he could stop, he couldn't control is urges.

Percy also had an interest in Coprophilia, Urolagnia (Urophilia) & Cannibalism. Obviously, we do not know if any victims were subjected to this vile treatment by him. The term "I don't remember" seemed to work for Percy. The police let him get away with that excuse for too long and ultimately the families were, once again, were left with no answers. These were Percy's memories that only he would know. He has the power, once again.

The only common denominator in this case and others - is the beach. That is it.

If Percy is responsible, where in an unfamiliar town to him would he take them? Back to his hotel? No-one saw children enter with him? No screaming or crying was heard by anyone? He had no friends, did he befriend someone else and then use their place? You have to think about the logistics of a POI in unfamiliar surroundings, packed full of people on holidays and on the beach due to the searing heat. Where/when/how and what becomes extremely difficult to piece together and is against the evidence as we know it.

In my opinion Percy had no involvement is this case.

To get this case active (like really trying to get answers) would be for SAPol to open their books and refer it to the Coroner for an inquest, which they refuse to do or drop the order on The Mulligan Inquiry. Both of these avenues hold the truth.

Could a 17yo on his summer holidays pull this off on his own though?

Entice the children, do the deed, dispose of the bodies, no witnesses, no remains, nothing.
It just seems so improbable.
I agree. Especially in an unfamiliar town. Where do you take them? Where do you get all your equipment to dispose of them? He has no resources here in SA.

His height, description doesn't match to what has been described in the BC case. 5'10 surfie looking man, most certainly does not describe Percy.

Height does match 5'10 to 6 ft and the photo below is a mugshot of him in 1969. Does he look his age, being 20 at the time? Police sketch of BC suspect for comparison.

"The suspect was described as in his 30s with light brown, short swept-back hair parted on the left side, a thin face and clean-shaven. He was suntanned and wearing blue bathers with a white stripe down the side.

Could it have been Percy? He was only 17 at the time but was sometimes mistaken for being older. His writings showed he planned to give food to the children he would kidnap before killing them. The Beaumonts were in the age group Percy fantasised about and they went missing from the beach, as did Yvonne Tuohy, Marianne Schmidt, Mary Sharrock, and Linda Stilwell."

They were comfortable around this person/s. Percy, without a doubt looked like a psychopath from very early on.

You mean like Ted Bundy, Edmund Kemper, ? What exactly does a psychopath look like?

Percy was about opportunity. The BC case was pre-meditated. It's too organised, for Percy. We have descriptions from witnesses that suggests prior contact with the POI.


We have people saying they didn't look distressed, is there a reason they should be at that point? The suggestion is nothing more than an assumption.

I do not believe that the children would have felt 'safe' with him and would not have left with him.

Except they weren't just with him, there were people everywhere at the beach.
Not to mention Jane's new boyfriend...

If they did leave with Percy - we would have many more sightings from witnesses - such as 'I was on the tram with these children, I saw them on a bus...' we have no confirmed sightings from witnesses other than what happened at the beach/bakery etc'.

We do and they didn't have to leave with him, just meet up somewhere else, to give him his meat pie perhaps?

"The police also talked to a local bakery employee familiar with the children as they had visited the shop many times before. She said that on the day of the disappearance, the trio came to the shop and bought a meat pie and some other pastries. The first peculiar detail was that they had never purchased a meat pie before, and when she asked them about it, they replied that it’s “a pie for the man.” The second anomaly was that they paid with a £1 note. However, their mother had only given them a few coins. This transaction led investigators to believe the children obtained the money from the man allegedly with them.

"The last confirmed sighting of Beaumont children was around 3 pm. They were seen walking alone, away from the beach, to their home. A postman, who knew the children well, told the they were happy and had stopped by to say hello. While police believed the postman’s claim, the authorities theorized the encounter happened before the noon, not 3 pm." (The postman also said it may have been mid morning)
There are other possible unconfirmed sightings also.

Percy also had an interest in Coprophilia, Urolagnia (Urophilia) & Cannibalism. Obviously, we do not know if any victims were subjected to this vile treatment by him.
You forgot to mention cross dressing and the Yvonne Tuohy Murder, I am not going to post the crime scene description here because it is disgustingly shocking (Coprophilia) but you can read about it here in the excerpts from the book.

The only common denominator in this case and others - is the beach. That is it.

No, the description matches, he has been placed in Adelaide by his brother, a family friend and himself. The ages of the children match his preferences also.

If Percy is responsible, where in an unfamiliar town to him would he take them?

Unfamiliar?, the family went to sailing regatas all over the country, are you assuming he had not been to Adelaide before, specifically the Glenelg area?
An abandoned house perhaps?

"Around nine months after the mysterious disappearance, a woman told the police that on the same night as the tragic event, she saw two girls and one boy accompanied by a man entering an abandoned house in the neighborhood. She added that later she saw the boy walking by himself. However, the man caught up with him and took him back. They had left by the next morning, and she had not seen them again. It is unclear why she waited such a significant amount of time before mentioning the incident. Due to her delay in reporting, the police never attempted to search the house."

Reading this will give insight into how children walk away with unknown strangers, and other aspects of Derek Percy.

For people looking towards Percy, I do not believe Percy is the POI. I believe police had backtracked through his movements thoroughly and have clearly stated that he is not a POI in the BC case. I have been told the reason that is, is because they backtracked thoroughly.

Have you got a link to this information?

Transcription Sen. M Roberts. 28 names list.

G’day, I’m Senator Malcolm Roberts. I want to talk now about a very serious issue that concerns all of us in our community. This issue offends every normal thinking person and it disgusts us all. I am talking about paedophilia, the sexual abuse of children by deviant adults for their own sexual gratification. There are a lot of stories circulating about this issue and I want to set the record straight. One such story relates to a document purportedly naming 28 alleged people under investigation for pedophilia-related activities. It was most famously discussed in a Senate Estimates hearing.

After extensive research by my office, we found that the Wood Royal Commission was provided a document that the Commissioner determined contained information outside the terms of reference of the Commission. It was returned to the provider. That’s it. The document is not in the public domain and is not held by the government. My inquiries revealed that it contained unsupported allegations against 28 people from an unidentified author.

Without an author, it’s wholly unverifiable and unusable in court. Publication of the contents may well constitute defamation in some circumstances. When starting this investigation, I had hoped to unearth evidence which if brought to light would prove and put away perpetrators of disgusting acts. Despite my best efforts, that is not what I found. There are plenty of urban myths about all of this. One of these is that the document is subject to some sort of suppression order, preventing its release. My inquiries revealed there is no suppression order on this document. There never was a suppression order.

The document simply isn’t credible enough without an author for anyone to publish outside of parliamentary privilege. My view, and that of One Nation, is that paedophilia is a blot on our society and that everything should be done to stamp it out. Offenders should receive the severest penalties when convicted as a deterrent to others and to keep our children safe. Those who would knowingly protect these offenders must also be identified and stopped, no matter what their roles in our society may be.

No one should be immune because of their status. Sexual misbehaviour in the legal profession has been highlighted in the media lately. Allegations have even been made towards the behaviour of judges, magistrates and senior lawyers. What is missing is a Federal Integrity Commission with power to review the behaviour of the politicians and the judiciary. An integrity commission with teeth would mean that any allegation of corruption, criminality or misconduct could be thoroughly and independently investigated. There’s no doubt there are still people in power that get up to no good; we need a commission that can properly investigate them and bring them to justice.

I have only ever heard that Percy was at Glenelg, or in Adelaide itself, in Jan 66' with his parents.
His dad had a car and he had to ask permission to use it!!


This might be of interest to a few certain members here, including Johnnymac1, Tues, TTT, and inspector Gadget even got a mention...
Over on another forum with the initials CM, there is a person there that swears they are not a member here in any way shape or form,
but they are replying to messages in there made by the above members in here!!

Ivé complained to their Admin and asked him to lock the thread, as he mentioned he would, but so far this person is still spouting their
BS, that the BC children are still alive and their mother was the one that got them "kidnapped", for want of another word..
I know he'll read this, (waving hi to Johnny S) but I really don't give a toss.
He has no idea about privacy and has given my Facebook user name to other members, although my page is pretty much locked down.
But please be careful of him, especially those ivé named above!!

If Percy was in Adelaide, holidaying around Glenelg Beach at the time of the Beaumont disappearance, exactly how long was he there for? Days? Weeks? Remember that the Beaumont kids were apparently in the company of their abductor long enough to gradually become comfortable with him. The abductor had to earn their trust over a period of time. This perhaps points to a local culprit, not a temporary visitor just passing through.

I'd like to know more about the story of the woman who saw three children entering an abandoned house with an unknown man. All were gone the next day and the place went back to it abandoned status. The boy was said to have been seen trying to escape before being recaptured. That would be a fascinating line of enquiry. No police search of the house was ever conducted, which seems odd.

If Percy could be charismatic and/or charming (I don't know if that's the case) he could potentially gain the trust of a young girl in one afternoon.

Apparently the abductor had been at the beach with the Beaumont kids more than once and got described as a 'new boyfriend'?

Yes, I think if he had spent 2-3 days with the kids prior to them going missing, he might be called Jane's new boyfriend, maybe in a teasing way. Especially if Jane really liked him, and maybe they'd held hands or kissed - summer love and all that. Whether or not it was Percy, I am leaning towards a young killer. Even in the 60s, I think kids would be creeped out by anybody older than 20 being the "boyfriend" of a 9yo.

In Lambs to the Slaughter on Derek Percy, just thought I should mention that I've just came across a paragraph where Debi Marshal has Percy getting his license at 18yo. His younger brother took advantage of the lowered age in NSW and got his at 17yo.

I always found it a bit odd that a person planning a abduction would make himself so obvious for witnesses to describe - although there were also 2 very different versions of the 'suspect' namely a young surfie with dirty blonde hair and a man around 35 years old.

I recall a witness account that saw three children fitting the BC description with a man and a woman near Durham/Augusta st intersection. There was even a sketch done. What was the conclusion with that? False lead?

I remember growing up in the 70s/80s that that specific area was talked about quite a lot in regards to the missing kids and this was a long time before the Satin Man theory was out there.

Going by Percy's contempt for absolutely everything maybe he drove without a license or even thought he would merely give his brother's name if pulled over? (and that book still haunts me)

Yeh, I skipped parts in the book the first time as a bit much but this second read is easier in small sessions. Urgh.

Percy admits to having fantasised about mutilating children since well before the Beaumont children disappeared and having been at Glenelg on the day they vanished.

Haven't heard of that sighting, the satin mans home is another block east, opposite a church.
Hayden in a statement, said four shots rang out on the day of the abduction.
Hard to believe no one heard or reported gun fire. noise would have echoed off that church.

The Satin man enquiry seems to be the only line of enquiry the police are following, hence the dig at castalloy

Re Percy
going through his lock-up, surely they would have found something linking him to the BC case?

They didn't find anything enough for a charge but there certainly was enough there to suggest that his fantasies involved taking more than one child at the same time. He's accused of the mutilation murder of 3yo Simon Brook with his writings consistent with Simon's injuries. Given he was already in prison for life with a 'crazy' pass I assume that went towards the decision not to prosecute him for it.

I can't post what he wrote in here, it's obscene.
