UFO Abductions: Fact or Fiction? Dr. Roger K. Leir, the “Alien Implant Doctor”

“Where’s the physical evidence?”

That’s perhaps the most popular question asked by opponents of the theory – not to mention first-hand reports – that ETs fly their UFOs around the planet, abducting cows and people, willy-nilly, upon whom they perform medical exams and sometimes-painful procedures (think “anal probe”).

In fact, there’s plenty of physical evidence. Here’s some. You be the judge!

Dr. Roger K. Leir, the American podiatric surgeon, known as the “Alien Implant Doctor,” is best known for performing 16 surgeries and removed 17 “alien” implants during his 40-year career. He challenged the conventional scientific community by showing physical evidence – the objects he removed – as proof of extraterrestrial intervention right here on good old Earth.


Dr. Roger K. Leir,

the “Alien Implant Doctor”


An avid UFOlogist from boyhood, Dr. Leir became the State Section Director of MUFON Ventura/Santa Barbara, CA. From his association with that group, two people from different parts of Texas brought him x-rays of foreign objects embedded in their bodies, unaccountable by prior surgeries, injuries or splinters:

1.) Pat Parrinellio, 47 years old, had an object embedded in the back of his left hand.

2.) “Mary Jones” (not her real name), 52 years old, had two objects in her left big toe.

On August 19, 1995, Dr. Leir and his surgical team removed these objects. Finding them curious – dare I say “unearthly?” – the foot-doctoring UFOlogist had two pathologists and several independent laboratories test and analyze the evidence.

Even as the first three implants were being studied, two more women from different parts of California – Dorothy O’Hara, 61 years old, and Alice Leavy, 40 years old – underwent surgeries on May 18, 1996, where Dr. Lehr removed objects similar to the first three! In January 1997 another foot surgery produced an object described as “crystalline” from a fourth woman, the 37-year-old Licia Davidson.

The first set of implanted objects tested positive for being metallic, but the second set of implanted objects did not. If these objects are, in fact, alien tracking or monitoring devices, could different objects perform different functions?


Of the 17 implants, Dr. Lehr said, in a video interview, that seven “look exactly the same… I’ve synthetically divided them into three categories: ones that are metallic and covered with a biological coating; ones that are non-metallic; and one that is biological. Each operates a little differently.”

From Dr. Leir’s files, implants he removed surgically




Are there biologist ETs out there tagging us like the wild animals we research?

Notable about all these cases was the absence of any memory, physical rash, scar, insertion point, or fever from these objects, raising the question: “What kind of technology or happenstance can explain how this object came to be inside my foot when I never had any surgeries in my life?”

“How do you get something into the human body and not have the body react to it? … You either have an inflammatory reaction or it’s a full-blown inflammatory reaction we call a rejection reaction. You just don’t get foreign material into the body and have the body sit there and smile at it.”  — Dr. Roger Leir, 12/04/09 televised interview

On May 30, 1978, Tim Cullen and his wife Janet were driving in Colorado. They stopped their car to get out and look at a UFO. When they got home, they realized they had lost an hour of time. Years later, an x-ray revealed an unexplained piece of metal in Tim’s arm. He sent his x-ray to Dr. Lehr who filmed the extraction surgery of a 6mm metallic object with many attached nerve cells (proprioceptors) that didn’t seem to belong there. Again, the patient said there had been no skin reaction or inflammation to mark the object’s original insertion.

“It is my opinion that someone, or some entity, from somewhere else, is implanting these devices into human beings so that they can monitor genetic changes which are occurring in the human body. — Dr. Roger Leir [“Penn & Teller: Bullshit!” episode 1.03, “Alien Abductions”]

Dr. Leir founded a not-for-profit organization called Alien Scalpel – A & S Research Inc. – to study bio and psych aspects of alien abduction. The company’s website reports:

“These objects have been scientifically investigated by some of the most prestigious laboratories in the world including Los Alamos National Labs, New Mexico Tech, Seal Laboratories, Southwest Labs, the University of Toronto, York University, and the University of California at San Diego. Their findings have been baffling…some of the tests show metallurgical anomalies such as highly Magnetic Iron that is without crystalline form, combinations of crystalline materials mixed common metals, growth of biological tissue into or out of metallic substances, as well as isotopic ratios not of this world.” [emphasis added]

After surviving severe cases of shingles and diabetes, at the 2012 IUFOC (International UFO Congress) conference Dr. Leir said, “Although I went through a terrible time, health-wise, for some reason, I’m still hanging around. And one of the reason’s I’m hanging around is to wait for disclosure to come.”

The following year, in 2013 he testified as a medical witness at the Citizens’ Hearing for Disclosure for the existence of ETs and UFOs.

Critics and debunkers claim that Dr. Roger Leir was seeking fortune and fame, that the objects removed surgically are not especially unusual, that the laboratories used for testing are not reputable, and that Dr. Leir refused to surrender his implants to his nay-sayers for them to test.

No one can argue that Dr. Leir achieved a fair degree of fame, particularly in the field of ufology. Among his book credits:

  • The Aliens and the Scalpel (1999) and Casebook: Alien Implants (2000) described his ground-breaking surgeries and his conclusions that these objects were of non-earthly origin.
  • UFO Crash in Brazil (2005) reported the results of his investigation in Varginha, Brazil into “the Brazilian Roswell” event of 1996, which featured multiple witnesses and military documentation.

Dr. Leir appeared in several television documentaries, including the History Channel’s UFO Hunters, and was a frequent guest on ufology podcast talk shows. He lectured in 42 countries and was invited to present at the prestigious Society for Scientific Exploration in Paris, France. He also looked into the 2007-2009 UFO sightings reported from Kumburgaz, Turkey.

The ground-breaking UFO investigator Dr. Roger K. Leir died Friday, March 14, 2014, never experiencing the full disclosure for which he “hung around”.

Returning to the critical question posed at the beginning of this article, given this – and other well-documented cases of ET and UFO activities – the analogous question on UFOlogy Street is:

“What will it take to get full ET/UFO disclosure?”

From the 1960s to the present day, alien abduction stories continue… and continue to get almost no serious mainstream media coverage. What does this mean to our society? Our past? Our future?

UFO Abductions: Fact or Fiction? Is an ongoing series of prominent alien abduction cases by ufologician LightWorker 111 that you will “encounter” at The Daily Conspiracy.
