Background and Police Career
Pucheta served as a corporal in the División Abigeato (Cattle Rustling Division) of the La Pampa Provincial Police, based in General Pico. By all accounts, he had an unblemished service record prior to the events of March 2006. Colleagues and superiors described him as dependable and psychologically stable. He had no documented history of mental illness and, notably, had shown no prior interest in UFOs or paranormal subjects before the incident that would define his public profile.
A few days before his disappearance, he reportedly mentioned seeing strange lights in the sky in the same rural area where the incident later occurred. This detail was noted by investigators but could not be independently confirmed.
The Incident of March 2, 2006
On the evening of March 2, 2006, Pucheta began a routine patrol at approximately 7:30 PM, covering around 80 kilometers of rural territory after agreeing to take on a colleague’s jurisdiction. Near an area known as “El cruce de las Cañas,” roughly 25 kilometers south of General Pico, he observed an unusual glow in the scrubland and stopped to investigate on foot, suspecting poachers.
Finding nothing, he returned to his motorcycle. At that point, two intense red lights appeared approximately 50 meters in front of him. He later described being immediately paralyzed from the neck down, able only to move his hands. He placed a distorted phone call to a colleague before contact was lost. When officers arrived within minutes, they found his Honda 125 cc motorcycle tipped over, his helmet on the ground, and his service pistol, radio, and cellphone disassembled in an orderly fashion nearby. There were no signs of a struggle and no footprints from any other person.
His own footprints led into the fields toward Meridiano Quinto. Police noted that the spacing between prints began at a normal stride but increased progressively, reaching gaps of up to seven meters over a span of 2,800 meters. A severe storm beginning at 2:00 AM erased remaining evidence and hampered the search. The provincial government mobilized a large-scale operation, involving the Minister of Security, the Police Chief, and multiple search units.
Reappearance and Testimony
Pucheta was discovered the following afternoon, March 3, 2006, at approximately 3:55 PM in an area known as “El Triángulo,” between 20 and 30 kilometers from where he had last been seen. Landowner Luis Alberto Barbero found him sitting motionless by a dirt road, his face buried in his arms. He was unresponsive to verbal contact.
When officers arrived, Pucheta initially said nothing, then embraced his commanding officer, Commissioner Inspector Roberto Osvaldo Ayala, and broke down. His uniform was clean, free of burrs, and completely dry despite a heavy overnight storm. His boots showed only dampness consistent with sitting on wet grass.
In subsequent statements, Pucheta described encountering small, transparent-looking beings with oversized heads and bright red eyes. He said they communicated telepathically rather than verbally, issued warnings, and caused him to relive memories from his childhood. He reported sensations of floating above the landscape and intense heat on his feet. He also described a warning that another solitary officer might be targeted in the future, and a voice inside his head telling him that if he remained in one place until evening, the beings would return for him.
“I felt I was inside my mother’s belly,” he told investigators, “and then I started remembering things from my childhood.”
He later expressed significant reluctance to discuss the experience publicly, telling a friend through an intermediary: “I don’t want to be taken for a nut.”
Medical and Official Findings
Doctors at Gobernador Centeno Hospital in General Pico documented burns and blistering on Pucheta’s feet, along with small puncture-like marks between the blisters. He experienced severe photosensitivity that persisted for some time after the incident. Despite 18 hours without food or water, he showed no signs of dehydration, a detail that medical staff and investigators noted as unexplained.
The case was formally filed under “S/Paradero” (Missing Person investigation) and managed by the Fourth Instructional Court of General Pico, under Judge Dr. Luis Alberto Abraham. La Pampa UFO researcher Oscar “Quique” Mario, known for his cautious approach to witness testimony, documented the scene and later stated that Pucheta’s account carried significant credibility, in part because of the corroborating physical evidence and the witness’s professional background.
Additional anomalies noted during the investigation included Pucheta’s cellphone having erased all stored numbers except the last one dialed, as well as inconsistencies in phone records that investigators were unable to resolve.
Aftermath and Retirement
Pucheta never returned to active police duty. The psychological trauma from the incident rendered him unable to work, and in May 2013, La Pampa Provincial Police issued Resolution 383, placing him on mandatory retirement. He has remained largely out of the public eye since, though he has periodically broken his silence in interviews with Argentine media. In one such interview, years after the incident, he reaffirmed his account and expressed that he never wished to experience anything like it again.
Significance in UFO Research
The Pucheta case is frequently cited in South American UFO research as one of the most evidence-rich alleged abduction incidents on record in the region. What sets it apart from many other accounts is the volume of official documentation: police reports, medical records, court filings, and testimony from multiple law enforcement officers who witnessed the aftermath. The strange footprint pattern, the dry clothing after heavy rain, the absence of dehydration, and the disassembled weapons were all recorded by authorities rather than relying solely on the witness’s word.
La Pampa province has a broader history of reported UFO activity and cattle mutilations, including the 1983 reported abduction of farmer Julio Platner in the same general region. The Pucheta case is considered the most officially documented incident from that area.
Reception and Criticism
Pucheta’s account received significant coverage in Argentine national media following the incident. UFO researchers, including those associated with Inexplicata: The Journal of Hispanic UFOlogy and the Institute of Hispanic UFOlogy, documented the case extensively and noted that the physical evidence distinguished it from typical unverifiable abduction claims.
Skeptics point out that many elements of Pucheta’s testimony, including telepathic communication, red-eyed beings, levitation, and childhood memory regression, align closely with patterns seen across global abduction literature, raising the possibility that cultural or psychological factors shaped how he interpreted and recalled the experience. No official investigation concluded that extraterrestrial contact occurred. Trauma, dissociation, and environmental factors have been proposed as alternative explanations, though none account fully for the physical findings or the footprint evidence.
