A new document has stirred debate after it claims a cache of leaked documents points to a long-standing secret US government program studying Unidentified Aerial Phenomena (UAP), commonly referred to as UFOs. Claims reported by the company New York Postcenters around documents allegedly linked to the former head of cybersecurity at Los Alamos National Laboratory in New Mexico.
Investigative reporter Jeremy Corbell, who is behind the documentary called Sleeping Dog, said he received the documents from the late official’s son.
The documents reportedly include notes, photographs and more
According to Corbell, the materials include internal memos, sketches and Polaroid images. He claimed that these documents indicated that US authorities had been studying the origin and purpose of UFOs for several decades.
“During my work as a journalist, I became a central clearinghouse for sensitive (UAP) material,” Corbell told the New York Post, adding that families of deceased insiders are increasingly coming forward with undisclosed records.
In the documentary, he tells how the son of a former laboratory official discovered the documents while sorting through his father’s belongings after his death.
The identities of those involved – including the official, his son and the scientists mentioned – were not disclosed in the film, reportedly due to security concerns.
Agenda of the 1991 meeting cited in the leak
One of the documents highlighted in the film is said to detail the agenda for the high-level meeting that took place on April 24, 1991 at Los Alamos. Representatives from agencies including the Central Intelligence Agency (CIA), the National Security Administration (NSA), the US Navy and the US Army are said to have attended the meeting.
The program reportedly referred to investigations into “atmospheric anomalies” and included discussions of incidents such as the 1987 Gulf Breeze sighting in Florida and the 1989 Belgian UFO wave.
Other topics mentioned in the meeting document included technological development of sensors, possible foreign input described as “Soviet offers” and potential collaborations with academic institutions such as MIT and Stanford.
The missing scientists add another layer to the mystery
The documentary also draws attention to cases of missing or deceased individuals connected to Los Alamos. According to the report, two of the 11 scientists mentioned in the larger story had connections to the lab.
Among recent cases, retired engineer Anthony Chavez went missing in May 2025 after going for a walk. Authorities said he left personal items behind, including his wallet and keys, and despite search efforts, he has not been found.
In a separate case, Melissa Casias, an administrative assistant at the lab, went missing in June 2025 after dropping off lunch for her daughter. She was last seen on footage walking along the highway.
Authorities reportedly found both her home and work phones reset and left behind, although no other details linking the disappearance to the claims made in the documentary have been officially confirmed.
No official confirmation of the UFO program
While the document presents the documents as evidence of a secret program, there is no official confirmation from US authorities to support these claims.
Originally established under J. Robert Oppenheimer as part of the Manhattan Project, Los Alamos National Laboratory remains one of the most secure and closely monitored research facilities in the United States.
The premiere of the documentary is scheduled for May 17.
Which remains unverified
The claims in the film rely heavily on documents that have not been independently verified in the public domain. The connection between alleged UFO research and missing individuals also remains unclear.
As such, while the documentary raises questions about secret research and unexplained incidents, its claims have not been substantiated by official investigations.
