🔴 BREAKING: FBI Officially Investigates Disappearance/Death of 10 Scientists・Trump Says “Pretty Serious Stuff”

Source: CBS News, Fox News (April 28, 2026)

Latest Development: FBI Takes Lead in Investigation into the deaths and disappearances of 10 personnel from sensitive U.S. nuclear weapons and space laboratories, involving NASA’s Jet Propulsion Laboratory (JPL) and Los Alamos National Laboratory. The investigation spans three years and is being conducted jointly by the FBI, the Department of Energy, and the Department of War (i.e., Department of Defense).

🔍 New Key Person Missing:

• Retired Major General William Neil McCasland (68) — Former commander of the Air Force Research Laboratory (AFRL), previously stationed at Wright-Patterson Air Force Base. Has been missing from his home in Albuquerque, New Mexico, since late February 2026, with no word since. His wife joked on Facebook that it “doesn’t seem like he was kidnapped to extract outdated secrets,” but acknowledged he had briefly focused on UFO document issues. [3]

🗣️ Trump’s Response (April 23):

“I just had a meeting on this issue… pretty serious stuff. Hope it’s just a coincidence… but some of them are very important people. We’ll continue to investigate.”

🗣️ FBI Director Kash Patel (April 26, Fox News):

“The FBI will lead the investigation, working jointly with the Department of Energy and the Department of War on this case.”

🗣️ Luis Elizondo (April 24, CUOMO Program): Elizondo revealed that the number of affected scientists is far greater than reported, and that some cases have “interesting common links to the UAP issue.” He mentioned that he and other UAP researchers have also been threatened, and pointed out that similar patterns can be traced back to the Manhattan Project era in the 1940s.

⚠️ Official Cautious Stance:

• Investigators say there is currently no evidence linking the cases
• Many cases are attributed to personal tragedies: an MIT professor was killed by a former classmate, others involved hiking accidents or unrelated events
• Former Department of Energy official: “People do die. Strokes, heart attacks, suicides, robberies—these things happen.”

Congressman Eric Burlison has referred the cases of McCasland and Sullivan (the Air Force intelligence officer reported last week) to the FBI, describing the events as “extremely concerning.”

📹 Featured Video: Nellis Air Force Base UFO — Strongest Evidence of 2026 or AI Fabrication?

Source: UAP Files, Multiple Social Media Platforms (April 19–28, 2026)

A UFO video allegedly taken at Nellis Air Force Base (Nellis AFB), Nevada, has been circulating wildly on social media since April 19, described by some as the “clearest UFO footage ever.”

📌 Video Content:

• Shows a luminous, structured object hovering in the night sky
• As the camera zooms in and out, the object remains clear and coherent, with very natural focus transitions
• Its silhouette bears some resemblance to a model from the legendary “sideways hat” base at S4 described by Bob Lazar

📊 AI Detection Results:

• ImgDetect/SightEngine Detection: 41% AI generation probability (inconclusive, cannot be determined)
• Some platforms like Instagram also claim detection results as high as 86% probability of AI forgery
• The zoom blur and focus shift effects present in the video are considered real shooting artifacts that current AI finds difficult to perfectly simulate

⚠️ Controversy Points:

• No original videographer identity, no official military confirmation — biggest red flag
• Community Notes on X platform once claimed the footage was an old video from North Carolina 13 years ago, but the link’s video upload date is April 2026, a complete contradiction
• Reverse image search results: all traces only go back a few weeks, no matching old footage found

💬 Analyst Perspective: Jimmy from UAP Files analyzed that this video is “neither easily debunked nor can it be confirmed,” highlighting that in an era of increasingly sophisticated AI technology, UAP verification requires standardized processes.

“When your gut says ‘this time it’s different,’ but your reason tells you to verify—that’s the biggest challenge in modern UFO research.”

Matthew James Sullivan, a U.S. Air Force intelligence officer who had been awarded the Bronze Star, died mysteriously from a drug overdose in May 2024 — just two weeks before he was scheduled to testify before Congress about the Legacy UFO Program.

🔍 Liberation Times Exclusive Reveal:

• Sullivan was allegedly directly involved in a Legacy UFO program reportedly related to non-human origin vehicle technology
• His work involved a private company collaborating with U.S. intelligence agencies
• Sullivan’s involvement reportedly began during his active duty in the Air Force
• Retired Major General William “Neil” McCasland (still missing), former commander of the Air Force Research Laboratory, was his superior

🗣️ Key Figure Statements:

• Congressman Eric Burlison (R-Missouri):

  “He (Sullivan) was scheduled for an interview, and then within two weeks, he ‘suspiciously committed suicide.’” Burlison has referred the case to the FBI for investigation, describing it as “extremely concerning”

• Air Force Major General David Abba (former head of the DoD’s Special Access Programs Central Office) spoke at Sullivan’s funeral:

  “He carried the weight of a national secret that only a very few truly understand, bearing that burden every day.” “There are very few people in this country he could share this with, but those who carry this weight know and understand.”

🤝 Connection to Whistleblower David Grusch:

• Sullivan had contacted renowned UFO whistleblower David Grusch (retired Air Force Major) before his death
• Grusch was helping Sullivan come forward as a whistleblower
• The two had served together in the Air Force
