Roger Leir was a California podiatric physician and surgeon who, from the mid-1990s, facilitated the surgical removal of a number of alleged alien implants and arranged for their laboratory analysis.1 His first such procedure took place on the 19 August 1995 surgery, when three objects were surgically isolated from two abductees known as Patricia and Paul.2 He went on to describe about a dozen further implant removal surgeries.3
The implants were analysed with support from the National Institute for Discovery Science, which arranged laboratory work at New Mexico Tech, an engineering university in New Mexico Socorro, using X-ray energy-dispersive spectroscopy and X-ray diffraction.4 The first three implant removals showed compositional results and isotopic ratios supporting the possibility of a meteoritic origin for the implant materials.5 Bill Chalker said these meteoritic-origin correlations were tentative, based on technical interpretations of meteorite data, and far from confirming an intelligent extraterrestrial source.6 According to “Hair of the Alien: DNA and Other Forensic Evidence for Alien Abductions,” the New Mexico Tech analysis itself offered a more prosaic explanation: a stone that had calcified after becoming embedded inside the body.7
Leir was also involved in the Gary Lowrey case. According to the same source, Gary Lowrey’s alleged experiences were investigated by a number of parties, including Leir.8 After consulting Leir, who had already made extensive enquiries into the case, Colm Kelleher felt that the claw sample recovered in the 2000-09 Gary Lowrey alien claw discovery could be a good candidate for DNA study.9
Whitley Strieber, who knew Leir well, said that when Leir first heard of the Varginha case in 2002 he telephoned Strieber and asked him to travel to Brazil with him, though Strieber’s schedule did not permit it.10 Strieber said that while Leir was in Brazil that year, he attempted to interview the widow of Officer Marco Eli Cherese, who would confirm only that her husband had died in hospital following the 1996 death of Officer Marco Eli Cherese and would not give further details.11 Strieber said that while in Varginha, Leir telephoned him to report that he had just conducted what he believed to be one of the most amazing interviews ever done in the history of UFO research,12 and Strieber has said he considers Leir’s Varginha interview to stand among the most amazing interviews done anywhere, on any subject.13 Strieber said he never doubted Leir’s truthfulness when Leir recounted the Varginha story to him.14 Strieber also said Leir noticed a change in attitude among the medical personnel he interviewed: they first claimed to be thirdhand witnesses, but as they talked it became clear they were in fact firsthand witnesses and participants.15 Leir separately interviewed Valquira Silva, who said she saw a short, crouching, motionless creature that was brown in colour, with oily skin and a large head.16 According to “The Fourth Mind,” one of the medical personnel interviewed by Leir said that none of the staff wanted to look into the creature’s eyes and refrained from doing so.17 A doctor was reticent to disclose everything he had received via what he described as thought grams during the incident, but was willing to describe what the creature had told him about human beings.18
Like John Mack, Leir’s licence to practise medicine was challenged, and he had to contend with a nuisance lawsuit that caused his practice to decline.19
