Extraordinary claims. Ordinary investigations.

The Screamin’ Demon of Mexico: Monkey Business


“Sometime around May 11, 2007, a wealthy Mexican rancher named Marao Lopez found this creature, less than one foot tall, in a steel trap. The property was in Metepec, … Mexico. … The creature was alive, shrieking and scared. … the ranchers decided to kill and preserve it the morning of the third day … They dunked it in water … for many hours, and it finally drowned. It’s ability to survive so long underwater has made many feel it was amphibious.
Within days, word about the strange creature had gotten to Jaime [Maussán]. … Jaime considered Marao Lopez an honorable man. Since Lopez was wealthy, and money was never mentioned as a variable in this situation, Jaime sees no motivation for a hoax. Jaime requested access to the body, now mummified, for tests at various universities. Around this period of time, Marao Lopez died mysteriously.”
The Screamin’ Demon Of Mexico By Joshua P. Warren

A very cheesy mystery thriller, full of plot holes and told by Jaime Maussán, illustrious member of Ufology’s Hall of Shame. So it’s really no surprise twist that the “Screamin’ Demon of Metepec” is just another hoax. Keep reading for the video and some ordinary investigations.


I do recommend that you read the full elaborate story, even if it can’t be taken seriously. Beyond that, there’s the actual evidence of a publicized image and the video. What is that?

“As far as I can see, the photo and the video are the same thing: a small primate from which someone removed the skin and part of the muscles. A squirrel-monkey is a good guess”, Maria Guimarães from Ciência e Idéias told us.

“I would guess it could be a species of Tamarin, since the position of the eyes is a little more farther apart than in the squirrel monkeys. The size of the cranium does not help to clarify things, but it’s bigger in the squirrel-monkeys. In any event, it’s indeed just a baby primate,” added Portuguese Biologist Bruno Galrido, author of Macacologia. “Poor creature, it must have lost itself and ended up in a trap”.

Below, the skeleton of a squirrel-monkey: (via National Geographic):


And from a Tamarin (via coyotter),


If it’s hard to believe someone would be capable of capturing a harmless little monkey, either a fetus without fur, or a small baby that was then skinned; only to then put it into a trap (as Vincent Boudreau noted on UfoUpdates, it’s impossible for the small creature to be captured in the foothold trap in that pose), to invent a whole load of bullcrap…

Then it’s because one underestimates the amazing bullcrap-generating abilities of some illustrious “researchers”. The report we quote here was originally published by Joshua Warren in his website, given that Maussán himself is holding this “evidence” for months already. In fact, he apparently still is, since he asked Warren to remove the material from the website because “the scientists involved did not want the attention to influence the perception of their results”.

Warren himself concedes that “these new developments do not help support the case for a find”. And indeed, if you are still swallowing even some of all that bullcrap, consider that Dr. Jose Antonio Lorente of the University of Granada, to whom “now, the creature has been sent …, undergoing the best DNA analysis in the world by one of the field’s top experts … As soon as the results are finalized, and all facts are compiled, there will be a world press conference in Spain, Mexico, or both, to unveil all the findings for the full scrutiny of the scientific community.”

Well, Dr. Lorente, as inquired by Vicente-Juan Ballester Olmos through Antonio Salinas and shared with Martin Shough

That Dr. Lorente said he has never heard of Jaime Maussán and that nothing of the sort has been sent to him, nor does he know if it is ever going to be. He also clarifies that he is an expert in human DNA, therefore even if he did receive a sample he would only be able to tell if it was human or not, but could hardly do much if it wasn’t, especially if it wasn’t of a known species.

It’s possible that some will now say that Lorente is part of the Great Conspiracy, or whatever other bullcrap they may come up with. Perhaps Maussán asked Warren to remove the report from his website exactly because it mentioned Lorente, a plot hole so easy to expose.

This whole cheesy paranormal thriller must be very familiar. With all the clichés including scientific analysis that is always about to be conducted, or was conducted, but from which we never get to see the results; with threats, deaths and everything else; where all sorts of things happen and the creature always vanishes at some point; this is all part of a pattern of similar stories related to the discovery of such imaginary creatures. It can be seen in the Garadiávolos tales, for instance. Just sea rays cut to look like humanoid creatures, the rest is pure, bad, fiction.

The senseless exploitation of harmless little creatures, including human babies, is sadly no news either. It can be seen in the Uberara “Alien” Skeleton case. The remains of a child with hydrocephalus and other congenital problems. The rest is pure, inhuman, exploitation.

The Screamin’ Demon of Metepec, Mexico, is just a small, skinned monkey. The rest is pure, distilled and aged crap.

    My first thought on seeing it was ” some kind of Jenny Hanniver…” (i.e., a “Fiji Mermaid” an animal corpse
    cut and modified after the fashion of the garadiavolos
    fakes ) and so it proves to be. Sadly, for every one
    responsible anomalist, there seem to be ten of these
    sensationalist trolls. It is an odious display, and the
    thought that a simple monkey might have been killed simply
    for the sake of this…story…is despicable.

    dna testing would be the logical course of action instead of speculating about it.

  5. Necro July 30th, 2009 10:53 pm

    Umm The History Channel did DNA testing and it has no DNA. It also has skin and has no muscle damage.

  6. Paranormal Fan August 2nd, 2009 4:55 am

    Necro’s right, It has ears that dont look similar to any other known species.Plus it had a much elongated skull than a monkey. And its more Human like than Monkey. PLUS why would that thing Have no DNA? Thats what’s really confusing…or maybe it was some government operation to breed a Humanoid like monkey rat thing…

  7. Jes August 3rd, 2009 3:36 am

    It also had human-esque ankles. If it was a monkey they would have recognized that right off the bat.

  8. sb August 8th, 2009 3:49 pm

    according to the show im watching on tv right now,aug 2009 , the animal is REAL. they have detemined that it has skin, what you see is actually its skin. So it is not some skinned animal

  9. Lasseter August 9th, 2009 10:29 am

    The creature was part of a MonsterQuest investigation. The body was tested, and the researchers found that the original skin was still on the creature, and DNA testing found that it was not related to any known species on the planet.

    I have a Big Problem with your explanation, a great German Newspaper with the name “Die Bild” shows a investigation of the corpus, the scientist say it is “real”. So you have explanation why the Scientist lie (from your view)? They´re paid from Jaime Maussán?

    Whom I have to believe… ? Make the Media a fun of us?
    We have already not to believe what is written in the newspapers? We live already in a World full of paid Junk Science?

    What is your view?

    cassio, if you read the German article, it’s reproducing exactly what Joshua Warren first publicized about the thing. Which Warren himself afterwards removed, on request by Maussán. And which, as is explained in the post, is not true, since the scientist they refer as the one analyzing the DNA didn’t receive anything at all.

    Some comments have pointed the creature has been feature on Monster Quest or some other TV show. I’m yet to check that.

  16. Sidd Reader August 27th, 2009 9:38 am

    Just for info: The BILD is indeed a big daily paper, but it is known as dubious and often unreliable.

    I don’t doubt, that the scientists in that film are, what they seem to be. But we don’t hear one comment by them in this video. Probably because they would have talked about a little monkey and not about alien DNS.

  17. jaho August 27th, 2009 12:00 pm

    it’s so incredible I can’t get enough of reading and surfing web in search of information about this thing. isn’t it some kind of relative of a famous el chucapabra?

  18. DannyTx August 28th, 2009 1:58 am

    The History Channel conclusion was not that it didnt have any DNA, it was that the DNA found was uknown..Also catscans were done on the corpse and found it too be legit

  19. ridelo August 28th, 2009 5:18 am

    >>The rest is pure, inhuman, exploitation.
    Inhuman? All too human, I’m afraid. Never seen a crocodile setting up such a show.

  20. martina August 30th, 2009 11:09 am

    why do people keep thinking we are the most perfect creatures in the whole universe? It would be quite sad, by the way… Maybe this is not an alian, but it does not mean they do not exist at all! The problem is in our mentality, we just dont wanna believe in it.thats it!

  21. dj September 3rd, 2009 6:30 pm

    well all the ufo sigting that we hear about u dont think its possible that some of them get left behing or possible put here for a reason. i want you to step back and think about this for a min. when you look back at the dinosaur age what where they know for……. killing, eating and surviving. look at our history…. what have we done, kill eat and survive. how did they discribe the creature to be, aggressive. now im not sayin that aliens are taking over the planet but u gotta wonder, are we really at the top of the food chain. I know i might be getting a little off topic but havnt u noticed that we are seeing or hearing about aliens more and more. its like second nature now a days. they do exist and that thing my friends is an alien. anyone who says different is just a closed minded person that is not opening them selves to new ideas.

    Saw the NatGeo special on the little creature from Mexico. For you sceptics I highly suggest you watch this special. First and foremost unlike monkeys this little dude has HUMAN FEET!! His skin is scaley. Monkees and small children DON’T have scaley skin. DNA was done on the creature but astonishly DNA couldn’t identify this little dude!! Anthropoligists looked at it and couldn’t figure out either what it is!!

    Urso Moreno Ruiz aka Angel Palacios Nunez
    appears as witness in this YouTube video:


    Urso is a taxidermist who declared in a reptile
    blog that he sunk a monkey in salted water mixed
    with other animal residuals to change any DNA
    results so that means the fraud was fabricated
    since 2008.

    The “Alien Baby” promoted by Jaime Maussan
    is exposed and confirmed as a fraud or hoax

    No..No..it’s real. None of these experts would be shipping a capuchin monkey carcass around the world if it was fake. The whole bit with “Urso Moreno Ruíz” is in fact disinformation. look closely.

  29. MIKE October 2nd, 2010 3:48 pm
