    Australia - Marianne Schmidt & Christine Sharrock, both 15, Wanda Beach, 11 Jan 1965

    Suspect in Wanda beach murders dies in hospital: NSW police have his DNA for testing

    July 24, 2013

    DNA taken from child killer Derek Percy before his death is to be compared to a sample found at the crime scene of the Wanda beach murders.

    It was revealed last year that a DNA sample was taken from a blood smear found at the scene from the murders 47 years ago.

    "The sample is very old and degraded and a lot of work needs to be done by the lab,'' said Detective Lehman

    Thanks for that information. If they have crime scene DNA then why hasn't it been plotted already?

    It would seem to me that Percy must be innocent of these murders. If he knew he was dying and knew the DNA would show he did it then why not just admit it?

    This my opinion and to the best of my knowledge, that is, if I'm not joking.

    Australia - 1965 Wanda Beach Murders

    On January 11, 1965, Marianne Schmidt and Christine Sharrock were brutally murdered at Wanda beach, near Sydney. The case remains unsolved.

    The girls had taken the younger Schmidt children out to the beach for the day. Leaving the young ones to rest while they wandered into the sand hills, the girls did not return to collect them. Christine and Marianne were later found brutally murdered, stabbed and bludgeoned to death. While both girls had not been vaginally raped, there was semen left behind on the bodies. There's been various suspects and leads, but as yet no arrest for the crime.

    Wanda Beach Murders - Wikipedia, the free encyclopedia


    Here's a look at the case from Crime Investigation Australia:

    https://www.youtube.com/watch?v=GIGqOD0Q9ec


    I strongly suspect the girls knew their killer, had met him on another occasion at the beach or earlier that day, and had planned to meet up with him as they set off into the hills without the younger children. Perhaps that who Christine was with when she went off her own prior to the murders. I also suspect the killer was young and not repulsive-looking, and may well have been the crab-fishing boy seen talking to them.


    What really strikes me is that while the murders were definitely sexual in nature, both girls were still virgins when they died. The frenzied stabbing looks then, like it may be an example of 'piquerism', where a killer substitutes a knife for his penis. He wants to rape (cutting away the clothing, etc), but cannot and the knife is used instead. As it seems the stabbing came -before- the clothing was torn away and semen was deposited on their bodies, I have the feeling the killer KNEW he couldn't rape in the usual way before he lured the girls out to the sand hills (which I think he did).

    I have to wonder if he had some sort of sexual deformity that left him too embarrassed to rape without rendering his victims dead/near death. Maybe he tried, or exposed himself, and the girls laughed at him... but I get the feeling he'd already been well and truly sexually humiliated/rejected prior to this crime and this was the killer's response to being attracted to the girls.

    I think he lured Christine out with a promise (made during the time she was off on her own earlier in the day) of alcohol (found in her system) or just charmed her into agreeing to meet, and this is why the girls made the little ones walk all that way before leaving them alone to continue in the 'wrong direction', into the hills. Having been a teenager myself long ago (heh) I recall going to greater lengths to spend a little time with a cute boy I met on holiday.

    I think this crime fits with a youthful offender, so that crab-fishing boy seems like a great suspect, to me.

    I also have to wonder if the killer hit Christine over the head first, then quickly attacked Marianne (cutting her throat, stabbing her repeatedly) and while this was happening Christine has come to and run off, screaming only to be hunted down, bludgeoned and dragged back to where he'd left Marianne.

    I wonder this because it'[d be hard for him to control both girls at once.

    Anyway, I have a lot of thoughts on this crime, I'd be glad to hear the thoughts/opinion of others.

    Certainly a bizarre, high risk and intriguing case. I have at #36 on my all time most interesting classic unsolved murder list.

    The "crab catcher" looks like a very good suspect with his knife and all but then you come up against the food and alcohol which throws everything off. Were there two unrelated weirdoes on the beach that day?
    This my opinion and to the best of my knowledge, that is, if I'm not joking.

    Interesting in that sexually motivated homicides are quite rare.

    He bore more than a passing resemblance to Richard Speck.

    One can hide stuff in the sand hills beforehand. What are you going to do with the crabs once you caught them?

    Anyway, overview of the case.

    -You have 2 victims killed in broad daylight at a populated beach however they were out of sight behind the dunes.

    -Both are stabbed one is beaten and stabbed

    -Killer brings, and takes weapon from scene

    -One assaulted, stabbed beaten then dragged, back to the body dump site

    -Both show signs of attempted sexual assault

    -Victims are killed where they are found

    -Bodies, buried to delay discovery

    -Post mortem indication of alcohol consumption by one of the girls .

    I watched the youtube video on the case , a few things stand out

    One of the girls brought food and drink of her own, which may possibly explain the origination of the alcohol, and possibly why the girls walked into the dunes, instead of walking down the beach back to their belongings.

    Perhaps they wanted to sneak a drink out of sight

    Another possibility is that the offender, offered alcohol to the victims, either by arranging to meet them somewhere in the dunes, or they happened upon someone who had it .

    I didn't see if the source of the alcohol, was ever discovered.

    An interesting fact is that the Killer brought the weapon to the beach, though the rest of the scene appears, to reflect a disorganized, offender type

    He brought a knife, but nothing to restrain a potential victim, nor was he able to carry out the rape of either girl, which to me indicates, at least to me that the rape wasn't planned.

    The attack appears to have been opportunistic, though there could've been some intermediate planning prior to the crime. Primarily if there was a prior arrangement to meet someone.


    Now, you have to assume, the killer brought the weapon, to the scene, for one of 3 reasons , 1) He planned on accosting a victim, or 2) he had it on his person for a legitimate reason 3) Or he was the type to carry a knife, for protection etc.. or as a macho thing

    The crime itself is extremely high risk for the offender, the victims themselves per lifestyle, were low risk, the only thing that elevated their risk, was that they decided to walk through the dunes, out of plain sight.

    For the offender to attempt to attempt to rape then kill then bury the victims there , I feel this offender was VERY comfortable in that location. He spent an inordinate amount of time there with both girls.

    The rape attempt is telling as well, though he was there alone in his place of comfort he wasn't able to rape either girl, however semen was discovered, though it doesn't indicate where on the victim it was .

    However in cases, like this its not unheard of for the offender to masturbate over the victim(s). But I believe I read somewhere the DNA was from blood.


    Even though he's in an area of comfort he still feels the need to bury the bodies, to delay discovery , which also signals some comfort at the scene as he took the time to do so .

    Because it appears rape was the primary motive in this case, we can begin to look through rapist typologies.

    There's a good amount of overkill, often indicative of anger, both girls are stabbed repeatedly, one is stabbed over a dozen times, one is hit hard enough in the back of her head to fracture her skull, she is stabbed multiple times, and her pants are "pushed up into her crotch" . Its suspected the rape attempt was while the girls were critically injured or dead, the clothes of the 1st victim, are cut off and pushed up above her breasts.

    The inherent rage to unknown victims, the inability to rape victims, beaten and stabbed to the point they are no longer able to resist. The comfort at the scene, taking time to bury victims, that aren't in plain sight to begin with, dragging a dying victim, from the beach back to the dunes, to hide the body in broad daylight .

    then you have an offender most likely covered in blood, who would have to break cover at some point, unless he went into the water to wash off prior, you're most likely looking at a local .

    Precipitating stressors, possibly fueled this attack, he most likely had the knife for a legitimate reason, he wasn't out hunting, but the victims, and the opportunity aligned, perfectly for him to assault and kill the girls.

    Part of this anger is most likely fueled by some form of sexual dysfunction, and these girls represented (either a real or perceived) target of what fueled his anger.


    there are 2 types of anger rapist

    1) Anger retaliatory (Displaced) which represents about 5-6% of all rape cases,

    2) Anger excitation (sadistic) which is the most rare type


    Given there is no evidence of torture, or prolonged suffering, I feel your offender is most likely closest to the 1st offender.

    Anger retaliatory rapist :

    The anger-retaliatory sexual murderer commits sexual offense with the intent of killing the victim during or after the sexual activity. The drive behind the anger-retaliatory murderer lies in a deep-seated hate toward women. This hatred stems from the offender’s sense of inferiority to a dominating female figure. Consequently, the offender’s victim is used as a surrogate for the figure that caused the killer to feel insignificant.

    This could be someone they slighted that day , and the opportunity presented itself.

    Thank you for the link, nadjatheresa.
    What a nasty piece of work this Derek Ernest Percy was.... even as a kid and a teenager. So young and so cruel! Makes one think twice about positive affirmations like if you can dream it, you can do it!

    I was watching the video from Crime Watch Australia, the part about the Wanda Beach Murder and I wondered why they would show a young man / teenager as the murderer, very bad taste and counterproductive IMHO but I suspect they opted for Percy.

    RichKelly, thanks for your thoughtful overview, and I tend to agree with you on all points.

    I think there's a chance Christine had met the killer previously, if not that same day during the time she was off on her own, then on a previous trip. It was Christine who had the alcohol in her system (the equivalent of one glass of beer), as well as the cabbage and celery (spring roll? coleslaw?).

    It could explain why they wandered (with the cranky younger children in tow) all the way down the beach and then took off in the 'wrong direction' into the hills, rather than simply going home again or picking a spot closer to where they'd left their belongings.

    I do think the person was living locally at the time, and probably found somewhere secluded to wash himself off in the ocean before going home.

    Very welcome.

    The girls actions are definitely suspicious, why would they leave the kids?. I can see one girl going back , but both leaving young children, seems strange.

    The sad part is that this guy most likely went on to a life of crime, possibly rape or further murders .... will have a history of bad relationships, abuse, drug and alcohol use. (your typical ******* type, with a hatred of women)

    Id guarantee he revisited the scene a few times, after . (Maybe even still does if hes still alive) ..but not for remorse, more likely to relive the situation

    Post Offensive behavior would be an over active interest in the case, more use of drugs, or alcohol, paranoia etc...

    I see 4 possibilities and only the first is very likely, that is, the girls had made prearrangements to meet some person or persons, most likely male, who turned out to be malevolent.

    The other three, unlikely, reasons they left the children were because:

    They just wanted to take a walk like they said, they went to find something hidden, probably alcohol, that had been left or the girls were in a physical relationship with each other and wanted to get away for that. In all the last three cases then the killer just happened upon them by chance.
    This my opinion and to the best of my knowledge, that is, if I'm not joking.

    They may've been followed by him, but it was almost certainly a crime of opportunity.

    Once everything aligned for him, he was gonna show them, all those girls who snubbed him, his overbearing mother who made him feel worthless , they fact they were just female they were going to pay .
