About
Missing Scientists, sometimes called the Eskridge Conspiracy is an internet conspiracy theory that began spreading on various websites and social media platforms in mid-2026 following the disappearance of former U.S. Air Force major general William Neil McCasland.
Origin
In late February, a retired Air Force major general named Neil McCasland stepped out of his New Mexico home for a walk and never made it back. Not long after, speculation began swirling online, with social media users suggesting the elderly former astronautical engineer, who supposedly ran a "UFO-linked" lab, may have been abducted or killed for his access to classified information.
Spread
As theories about McCasland's disappearance spread online, additional instances of scientists disappearing or being killed, dating back to 2023, began surfacing. Another scientist, an advanced materials researcher at NASA’s Jet Propulsion Laboratory named Monica Reza, had vanished while hiking near Los Angeles in June 2025. Months earlier, in December, a physicist at MIT had been found murdered.
As these cases surfaced, internet users began compiling a list of "missing scientists," though other disciplines and occupations seem to be included, and asserted that the cases were connected or part of a larger plot to suppress information.
On April 17th, 2026, Press Secretary Karoline Leavitt posted a clip from a recent briefing to the official @PressSec X account, in which a journalist raises the question of the missing scientists, adding: "No stone will be unturned in this effort, and the White House will provide updates when we have them." The post received 550,400 views and 11,000 likes in about one week.
In light of the recent and legitimate questions about these troubling cases, and President Trump’s commitment to the truth, the White House is actively working with all relevant agencies and the FBI to holistically review all of the cases together and identify any potential… pic.twitter.com/SJ9thaFegh
— Karoline Leavitt (@PressSec) April 17, 2026On April 20th, 2026, NASA spokesperson Bethany Stevens posted a statement to the @NASASpox X account, quoting the original @PressSec video, writing: "NASA is coordinating and cooperating with the relevant agencies in relation to the missing scientists." The post did not see much traction on the platform.
On TikTok, rumors began spreading that scientist Amy Eskridge was killed for discovering a means to generate unlimited energy, or that she had interacted with extraterrestrials. On April 21st, 2026, TikTok user @unknownphenomena posted an out-of-context clip of Eskridge discussing "ultraterrestrials," which received 2.5 million views and 252,900 likes in just three days.
@unknownphenomena 11 scientists. Dead or missing. Why? Amy Eskridge spoke about ultra-terrestrials… Not beings from space -- Beings already here. She referenced P47s, P52s, and claimed the info came from Hal Puthoff Now she’s gone. And she’s not the only scientist.
