Documentary Reveals Leaked UFO Files from Lab Linked to Missing Scientists

A documentary titled "Sleeping Dog" presents documents leaked from the deceased cybersecurity chief of Los Alamos National Laboratory, showing U.S. government involvement in secret UFO studies for decades. The files, provided by the chief's son to reporter Jeremy Corbell, include internal memos, drawings, and Polaroids.

Corbell stated that these documents confirm a long-term program to determine the intent and origins of UFO pilots. One document details a 1991 meeting at the lab attended by representatives from the Central Intelligence Agency, National Security Administration, Navy, and Army.

The agenda covered investigations into atmospheric anomalies, including the 1987 Gulf Breeze UFO incident in Florida and the 1989 Belgian UFO wave. Discussions also addressed Soviet offerings, sensor development, and interfaces with civilian sectors such as universities like MIT and Stanford.

Laboratory, founded by Robert Oppenheimer, has links to recent disappearances of U.S. scientists. Two former employees vanished in 2025: retired engineer Anthony Chavez, last seen in May while on a walk, and administrative assistant Melissa Casias, who disappeared in June after dropping off lunch for her daughter.

Authorities noted that Chavez left his wallet and keys at home, and Casias's phones were reset to factory settings and left behind. Surveillance footage showed Casias walking alone along a highway. Her husband also works at the lab. Searches for both individuals have not located their bodies.

Corbell reported knowing some scientists personally who never disclosed their UFO studies. The film is set for release on May 17. Air Force Gen. William McCasland, described as a gatekeeper on UFO subjects, is also missing and had indirect ties to the lab through oversight of nuclear research programs conducted there.

Sources report a total of 11 missing or dead U.S. scientists. President Trump addressed the disappearances on April 16 from the South Lawn. He told reporters from the South Lawn, “I hope it’s random.

“I hope it’s random. Some of them were very important people, and we’re going to look at it over the next short period.”

Corbell described becoming a central clearinghouse for sensitive unidentified aerial phenomena material, with families of deceased insiders routinely contacting him. He noted receiving the documents after the chief's son discovered them among personal effects.
