Will the Real Derrel Sims Stand Up?

Derrel Sims' nickname "Alien Hunter" describes his sometimes controversial approach to the phenomenon of alien abduction perfectly. He is a big man with a no nonsense stance about him, not surprising since he worked for the CIA in covert operations during the Vietnam war for two years.

This ex-soldier, who is himself an abductee, likens the operations of the aliens to that of the CIA itself. "If you treat the alien presence as if they are an intelligence community, you will make far more sense out of what they do, because they are secretive, they tell lies and they lie consistently -- well that sounds like most intelligence communities I've ever heard of."

Sims' approach to the phenomenon reflects his military outlook, he believes if they keep secrets then they do so because they are vulnerable. If they are vulnerable then there is an opportunity to fight back. He gets very annoyed at the passive approach to dealing with abduction. Because the abductors display remarkable feats of technological sophistication doesn't mean they we should just lie down and accept whatever they do to us:

"I personally don't believe the human race was seeded by aliens, as many in the UFO community do." He insists, "If you believe this then it leads to the kind of thinking that -- well they probably created us so therefore anything they do is all right. I find this mentality very disconcerting."

Although he thinks that the agenda behind abduction is complex and that there are a whole series of different programmes going on, he believes much of it revolves around a fundamental biological and genetic issue. [DNA -- "the mystic tie that maketh men brethren" -B:.B:.] Pointing to his lecture audience he says:

"I think human beings are one of the greatest things ever created and it wasn't by them. They want what you have, but they don't want you to be part of what they have got. They are clearly doing some astounding things in terms of genetics, but there is obviously something about the human species that is so incredible that they are prepared to go to enormous lengths to get at you and to do it without you knowing by trying to implant screen memories. Why all the secrecy? If we are just lab rats why don't they just tell us?"

Sims was abducted as a child of three and has since been multiply abducted. He described his first abduction as terrifying, when he awoke to find a "grey-type" creature by his bed, he was paralysed but managed to struggle and fall off the bed. When the creature pushed the bed away he saw its face: "It had large round eyes. They seem to have changed models on us since then like going from Fords to Cadilacs. What does that tell you?"

In one case he investigated he told me that the woman struggled with a creature that had the same round eyes as his abductor. She managed to fight back and knocked out one of the alien's eye shields, revealing its structure which was composed of five separate areas with little lines moving back and forth across the eye.

Sims is deeply involved in investigating the physical evidence that can be obtained from abduction cases. He is extremely cautious in his methodology, always sending any artifacts to the scientific and medical community for expert examination. He has managed to obtain a number of alleged implants from abductees, which vary from the more usual tiny metal and ceramic objects to more unusual things like teeth. He obtained these from an actress who was to star in a film on abduction and for which he was employed as technical adviser. Remarkably the actress claimed to be an abductee and gave him her teeth which had been removed by her dentist.

Although currently under scientific investigation the bizarre aspect to the case was that the dentist stated that due to the size of the teeth they could only have come from a man who had to have been over 6ft tall and weighing 300 lbs.

As to the aspect of abduction that 'the Greys' are creating a hybrid species, Sims is cautious and states: "I can't be sure this is happening until I have hard evidence I can validate." However as far as the aspect of false pregnancies, which are such a common feature of abduction he told me he is currently investigating a number of cases. "The best case I have seen so far is a woman who claims to have been abducted and has physical evidence to corroborate her claims.

What is so interesting is she claims to be a month pregnant but she had an operation eleven years ago to have her tubes tied and is therefore infertile. Her family have also been through some extraordinary events and they tried to move her secretly to another house in the hope of avoiding another abduction. It didn't work."

Sims likes to emphasise the vulnerability of the aliens and to demythologise their power. During the lecture he has the audience in hysterics when he shows a cartoon of a human grabbing a startled alien by the neck:

"Anything that has habits can be caught and trapped, so long as the trap is elaborate enough, this is why humans can be caught. Very few wild animals can be caught by traps because they don't have regular habits. The aliens have an agenda they must follow at all costs and this makes them vulnerable. They are not demi- gods, they often make mistakes."

To illustrate this point he describes a tragic case he investigated which involved a woman who had two young children, both of whom had experienced multiple abductions. On one occasion the children were taken from a shallow paddling pool they were playing in.

"Unfortunately, explains Sims, when they were returned, the aliens mistakenly dropped them back into the neighbour's pool, which happened to be 12 feet deep and the children drowned. The pool was surrounded by a 12 feet fence and there was no way these kids could have scaled this fence."

Sims conducted an experiment in alien communication, when he located a woman who he described as more of a contactee than of an abductee mentality. The woman who claimed, remarkably, that she "picked up every two or three weeks by the same group of aliens" and had been for the last 30 years.

Sims implanted a post hypnotic suggestion into the woman's subconscious. A sort of hidden message that she could not access consciously.

"Apparently something happened when the lady was picked up a few weeks later." Explains Sims, "When she came to within 20 inches of the alien, this had the effect of triggering the hypnotic suggestion which was communicated to the alien. The woman said the result of this was that for the first time in 30 years she saw an emotional response from an alien."

It is rather unorthodox experiments like this that have given Sims a controversial reputation within the UFO community. Yet he is methodical when it comes to investigating physical evidence and has spent huge sums of money having such evidence examined by scientists. He is currently investigating the bizarre phenomenon of fluorescent markings that can only be seen on abductees when 'black light' or ultra violet light is shone on the skin of abductees.

This phenomenon is far more common than previously believed and Sims has documented cases of abductees who are astounded to discover strange shapes and markings on their skin when exposed to 'black light'. "This is some kind of fluorescent liquid which has been placed underneath the skin and cannot be washed off, only removed by scraping off the skin with a knife. It is usually green and I have an example of someone with a double crescent shape on their neck. In one extraordinary case the person found the shape of the Mandelbrot Fractal inside their arm."

When I asked Sims if he thought the implants functioned as some king of tracking device he thought this explanation too simple and that all abductees don't necessarily have implants in their bodies." I'm just speculating here but I think they are more to do with modifying the behaviour of abductees, possibly by controlling the levels of certain neurotransmitters in the brain, such as Serotonin."

As to the issue of whether the scientific examination of implants will prove they are extraterrestrial, because they are made of some exotic metal not in the periodic table, Sims is skeptical.

"I don't think we will find that kind of result and we haven' so far. I think this is because if it was an 'alien' metal then the body's immune system would reject it."

Although 'The Alien Hunter' has yet to catch a live alien kicking and screaming, Sims' more aggressive approach to alien abduction seems to be having a significant impact on the way people view the phenomenon. He has certainly managed to instill in researchers and abductees alike a sense of self-empowerment and that it is possible for the abductee to fight back and not to lie back passively. In one case Sims explains:

"The aliens demanded that a woman enter the craft, but she stood her ground and said no. They then told her that if she didn't obey she would never see her parents again. She still held firm and said no. Do you know why she said that? Because she knew they were lying."

Sims, Leir Say They Might Have Hard Evidence of Abduction

This article summarizes a lecture given by Dr. Roger Leir at a public meeting in Thousand Oaks, California on February 23, 1996, sponsored by the local chapter of MUFON (the Mutual UFO Network). Dr. Leir is a California surgeon who has removed what may be actual alien implants from two people brought to him by hypno- anesthesia therapist and abduction researcher Derrel Sims of Houston, Texas. Derrel Sims was the main speaker at the Thousand Oaks meeting but turned the podium over to Dr. Leir for the medical part of the presentation.

On August 19, 1995, several alleged "implants" were surgically removed from two abductees who have been working with Sims. If preliminary findings are confirmed by further laboratory testing, these implants might provide hard evidence that the abduction phenomenon is a reality.

Dr. Leir removed a total of three objects, two from one patient and one from a second patient. Both specimens in the first patient, a woman, were located in her large toe, one on each side of the toe. The third object was removed from the back of the left hand of the second patient, a man, slightly above the web area between the thumb and the index finger.

According to Sims, these people were originally unaware that they had the implants. The objects were accidentally discovered on x-rays taken for unrelated reasons. At the time, these individuals were seeing Derrel, as there were indications that they had a history of abduction. After extensive interviews were taken by Derrel, he ordered copies of their medical records and these objects came under scrutiny. There was no pain associated with these implants, and neither patient had any prior sensation of foreign objects in the body. Another peculiar fact is that these implants also left no sign of entry into the body; if there was an initial incision, it healed so perfectly that there was no outward scar.

To help locate the implants more specifically prior to surgery, Dr. Leir used a stud finder and a gauss meter. A gauss meter measures electromagnetic fields. When the gauss meter was put near the object in the man's hand, the meter "went crazy." Dr. Leir first tested the man with the gauss meter indoors, then took him outdoors away from all other magnetic influences. The results were the same. Similarly, when he used the stud finder, it lit up brightly over the man's hand, so they knew there was something there.

Prior to the surgery, both individuals received a type of local anesthetic which would normally anesthetize the area of surgery for up to six hours. While Dr. Leir was searching within the woman's toe for the first implant, he accidentally touched the object and the patient "almost jumped off the table." Dr. Leir explained that the only time a surgeon gets this type of pain reaction under anesthesia is when something, in this case the object, is in close proximity to a nerve fiber. This is because the nerve fiber arouses the sensation of pain directly in the patient's brain, outside of the field of anesthesia. This happened in all three spots with both patients. When the objects were extracted, both patients had the same painful response. This led Dr. Leir to the realization that these objects were somehow attached to nerves.

The first object removed was flat and approximately triangular shaped, about half a centimeter on each side. Though metallic inside, it was covered with a thick, dense gray membrane. Dr. Leir tried to cut into the membrane with a scalpel, but couldn't.

When foreign objects have been in the human body for a long time, they do get covered with a dense fibrous coating, but usually such material can be scraped off with a blade. In this case, however, the membrane was nearly impossible to remove. A similar coating was found on all three objects.

Dr. Leir's next concern was how to safeguard and preserve the objects until they could be transported to a lab for analysis. In other cases of alleged implant retrievals, objects have reportedly turned to powder, disintegrated, or somehow disappeared. Dr. Leir decided the safest way to store these objects for transport was in the patients' own biological fluid. He had his nurse withdraw blood from each of the patients, then removed the serum in a centrifuge, mixed it with an anticoagulant preservative, and placed each implant in a vial filled with the fluid. Derrel Sims then took them back to Houston for further analysis.

Dr. Leir was responsible for the biological end of the implant research. So, after the objects were removed, he sent samples of surrounding tissue to a local pathologist. When the objects were taken out, Dr. Leir had noticed that the tissue around them was a discolored gray tone, not the color normally seen in tissue inflammation surrounding a foreign object. He received three reports back from the pathologist, one for each of the tissue samples. He was excited to see that none of the samples showed any signs of inflammation.

Normally there is an inflammation response to any foreign object in the body. This results from white blood cell activity in the area, attempting to rid the body of what it considers garbage that doesn't belong there. If the object is something soft, like a sliver, the body is able to disintegrate it and take it away one piece at a time. If the body can't remove the foreign object, it does the next best thing. Thousands of cells join together in a process called differentiation, changing form and surrounding the object to wall it off and separate it from the rest of the body. Any type of foreign object placed in the body -- whether by accident, such as a splinter, or something surgically inserted by a doctor -- will show this type of inflammation. So it was extremely strange that the pathology reports on these objects showed no inflammatory cells at all.

Another strange thing was also discovered. In the tissue around each implant, there were numerous nerve endings that didn't belong there. None of the investigators could say why these nerve endings were there, but it suggests the possibility that the implants act as some kind of monitoring device through attachment to the nervous system. [but not a control device? -B:.B:.]

When Derrel Sims got the objects back to Houston, his first test was to expose them to ultraviolet light. He found that they all glowed brilliant fluorescent green. Derrel has found in his research with abductees that patches of some substance, invisible to the naked eye but fluorescent under black light, sometimes show up on the abductee's body following an abduction. He suspects that whatever this substance is, it could result from direct physical contact with the body of the abductor. With this in mind, he said he was not surprised to see that the three removed objects were fluorescent.

Later, Derrel dried out the three objects, and the membranes surrounding them became quite brittle. He was then able to scrape some of the membrane material off and send it back to Dr. Leir for analysis. After scraping off the brittle membrane, he found a highly magnetic, metallic, shiny black material inside.

When Dr. Leir received the three different scrapings of the membrane coatings from Derrel Sims, he sent them out to three separate pathologists. When the reports came back, it turned out that the main ingredient in this very tough membrane was something simply made from blood. In this bloody mass were some brown granules. The pathologists did an iron stain test and found that these brown granules were made of oxygen-carrying pigment from human red blood cells. Besides this, they also found a material called keratin, which comprises the outer layers of human skin, hair and fingernails.

Dr. Leir pointed out that if medical science could figure out how to duplicate this membrane, we would solve one of the biggest problems in medicine, that of transplant rejection. The membrane around the objects was apparently composed of material from the patients' own bodies BEFORE the objects were inserted. If we knew how to do this, we could put almost anything into the human body and have absolutely no rejection. [the ramifications are disturbing indeed -B:.B:.]

Leir and Sims illustrated the structure of one of the implants taken from the woman's toe. When first removed, it was flat and triangular (as previously described). When the outer membrane was removed, inside were two separate pieces of shiny black metal, tightly joined together in the shape of a "T". Apparently only the membrane itself held these two metal pieces in alignment.

On February 22, the first preliminary lab reports came back on the metal itself. Leir and Sims both said they would await the final reports before announcing any details. They stressed that they had sent the samples for testing to highly specialized labs and had not indicated anything about where the samples came from. Dr. Leir told the Thousand Oaks audience that the preliminary findings are "mind-boggling," and that the first metallurgist simply said: "Wow, you guys really found something here." Dr. Leir stated that as soon as they get final reports from all three labs, they will make their findings public. "I think you're watching history," he said in conclusion.

Prior to working with Derrel Sims on this project, Dr. Leir had been an occasional consultant for MUFON, but had not been deeply involved. Now, he says, this project "has literally changed my life!"

Derrel W. Sims, C.Ht, R.H.A.

Mr. Sims is Chief of Abduction Investigations and Director of Physical Investigations for the Houston UFO Network. He has a uniquely new, progressive and proactive approach to his work and has managed to invoke a response from the alien presence as opposed to only reacting to them or just generating piles of case files. His methods of information retrieval and procedures in research resulted in a mass abduction in December 1992. Mr. Sims, who is an abductee himself has spoken before 250 doctors at a major hospital regarding medical implications of the phenomenon and has been invited to St. Petersburg, Russia to present at the Int'l Scientific Congress.


In his 25 years in investigations, he has implemented the use of innovative tools such as graphoanalysis, symbolic profiling, and genetic testing. Mr. Sims emphasized the necessity of obtaining hard physical evidence, and the analysis of the same (via non-UFO related medical and scientific professionals) in the paper he and Mary Florey M.S., R.C.Ht. presented to the Int'l Forum on New Science. For years he has been providing investigations and hypnotherapy at no charge to persons involved in the abduction phenomenon.

His background is as follows:

  • Registered Hypno-Anesthesia Therapist

  • Certified Medical Hypnotherapist

  • Member of the National Board of Hypnotic Anesthesiology

  • Certified Master Hypnotherapist

  • Master Level Neuro Linguistic Programming (NLP)

  • Ex-Senior Military Police Officer

  • Former CIA background (Covert Operations)

Mr. Sims' work, after being reviewed for over a year, was selected for use in an interactive display area for the Space, UFO, Science and Technology Center for the city of Hakui, Japan. He was honored by the city fathers with a plaque and an honorarium for the use of his expertise in the museum. Mr. Sims' work, which focuses more on hard evidence seeks to bring credible findings to the medical and scientific communities.
