Missing Scientists

Missing Scientists & Time Travel: Nobody Knows What Is Going On

2023-12-22. That’s the date. The post contained just two words, typed from a ghost account on X (formerly Twitter) with a Pepe the Frog avatar: ‘Cole Allen.’ For the next two and a half years, it sat there. Unseen. Unknown.

Then, on April 26, 2026, a 31-year-old indie game developer and Caltech graduate named Cole Tomas Allen allegedly shot his way into the White House Correspondents’ Dinner in an attempt to assassinate the President of the United States. And suddenly, that two-word post became the most compelling and terrifying digital artifact in the world.

This isn’t a story about proving time travel. It’s not about proving anything. It’s about a pattern. A list of names, dates, and institutions that connect a violent political attack in Washington D.C. to a string of dead and missing American scientists. It’s about the bizarre coincidences, the institutional silence, and the official story that asks you to believe it’s all just bad luck.

The facts require you to believe that a man who attended Caltech and was a fellow at NASA’s Jet Propulsion Laboratory (JPL) tried to shoot the president. And at the same time, at least four professional peers from that same Caltech/JPL ecosystem have been murdered or have vanished. It’s a lot to ask.

It sounds like the plot of a spy thriller: a string of brilliant minds, all connected to America’s most sensitive research in nuclear energy, aerospace, and advanced physics, start disappearing or dying under mysterious circumstances. But this isn’t a movie. This is a real-life mystery unfolding across the country, and it has lawmakers and federal investigators scrambling for answers.

 

Over the last few years, at least 11 scientists and technical specialists have either vanished without a trace or been found dead. These aren’t just any researchers; they’re individuals from top-tier institutions like Los Alamos National Laboratory, NASA’s Jet Propulsion Laboratory (JPL), and MIT. They held the keys to classified projects, from planetary defense systems to next-generation fusion energy. 

The Tweet, The Shooter, and The Engineer

Let’s zoom out for a second. The X account, display name Henry Martinez, was created in December 2023. It has no bio. Its one and only post is “Cole Allen.” The account’s header image is artwork from the homepage of a real European academic project called the Time Machine Organisation, a consortium dedicated to digitizing cultural archives. A clue? No. A red herring for the terminally online.

The reality is stranger. The shooter, Cole Tomas Allen, is a documented former fellow at NASA’s JPL, where he interned in the summer of 2014 while studying at Caltech. For six years, he worked part-time as a science and math tutor. In other words, he was one of them. A member of the same elite scientific community that is now shrinking under the most suspicious circumstances imaginable.

So who is Henry Martinez? 

Online researchers found him almost immediately. A Lockheed Martin aerospace engineer named Henry Martinez co-authored a NASA technical paper on the Orion space capsule’s separation system. The date of the paper’s symposium? May 2014. The same year Cole Allen was at JPL.

Is it the same Henry Martinez? We don’t know. Does the tweet’s foreknowledge mean the account owner was involved? We don’t know. Could it have been a reply to a since-deleted tweet or a reference to a different Cole Allen? Absolutely. The ambiguity is the point.

In an era where our information ecosystem is fracturing, discerning fact from fiction is a matter of national security, something we’re about to test in real-time during the deepfake election. Right now, the tweet is simply an anomaly. A digital ghost a full two years ahead of a gunshot. But it’s the institutional overlap that matters. The connection—whether coincidental or causal—is the NASA/JPL ecosystem. And that is where the story gets much, much darker.

The 11 Who Vanished

Cole Allen isn’t the only person from America’s advanced scientific community to make headlines. He’s just the only one who has been found alive. An FBI probe, a Congressional investigation, and a statement from the White House have all confirmed they are looking into a pattern of at least 11 dead or missing U.S. scientists and researchers. Some have mundane explanations. Others are so strange they read like a spy novel.

Why This Case Sticks

Amy Eskridge, 34

Co-founder, Institute for Exotic Science (Propulsion)

Deceased (June 2022)

Sent a text that read, “If you see any report that I killed myself, I most definitely did not.” Ruled a suicide.

M. David Hicks, 59

Research Scientist, NASA JPL (Asteroids/Comets)

Deceased (July 2023)

A prominent JPL scientist. His family cited “known medical issues” but the official cause of death remains unreleased.

Frank Maywald, 61

Principal Investigator, NASA JPL (Space Instrumentation)

Deceased (July 2024)

The second senior JPL scientist to die in a year. Again, no public cause of death.

Anthony Chavez, 78

Retired, Los Alamos National Lab (LANL)

Vanished on foot leaving his phone, wallet, and keys behind at his home.

Monica Reza, 60

Director, NASA JPL (Materials/Metallurgy)

Missing (June 2025)

Vanished while hiking. Her companion said she was right behind him, until she wasn’t. Her family doubts the official story.

Melissa Casias, 53

Admin, Los Alamos National Lab (LANL)

Missing (June 2025)

Disappeared leaving her car and a factory-reset phone behind. The phone wipe is a massive red flag.

Steven Garcia, 47

Contractor, KC National Security Campus (Nuclear Components)

Missing (August 2025)

Left his home on foot with a handgun, leaving his phone and wallet. Held a top-secret clearance.

Nuno Loureiro, 47

Director, MIT Plasma Science and Fusion Center

Deceased (Dec. 2025)

Shot and killed by a disturbed former classmate with a personal grudge. A clear motive, unlike the others.

Carl Grillmair, 67

Astrophysicist, Caltech (Near-Earth Objects)

Deceased (Feb. 2026)

Shot and killed by an erratic neighbor during a home-invasion carjacking. Tragic, but not a mystery.

William McCasland, 68

Ret. AF Maj. Gen., Fmr. Cmdr. Air Force Research Lab (AFRL)

Missing (Feb. 2026)

A 2-star general who ran black projects on hypersonics and directed energy. Vanished from home without his phone.

Jason Thomas, 46

Associate Dir., Novartis BioMedical Research

Deceased (Found Mar. 2026)

Authorities suspect no foul play; his wife said he struggled with grief. A personal tragedy, not a conspiracy.

The Patterns

When you put the list on a wall, the clusters are impossible to ignore. It may not be random.

First, the JPL/Caltech Cluster. 

Cole Allen (shooter), Michael Hicks (dead), Frank Maywald (dead), Monica Reza (missing), and Carl Grillmair (murdered) all worked at or were educated within the Caltech/JPL ecosystem. This is the story’s center of gravity. It is the only thread that directly connects the shocking political violence in D.C. with the quieter, more mysterious pattern of disappearances. It makes the Jet Propulsion Laboratory an institutional ground zero.

Second, the New Mexico Nuclear Cluster. 

Anthony Chavez (LANL), Melissa Casias (LANL), Steven Garcia (nuclear contractor), and Maj. Gen. William McCasland (AFRL, based in NM) all vanished in New Mexico. Three of them disappeared in a nearly identical fashion: on foot, leaving behind their digital footprint (phone) and often their wallet and keys. This isn’t how people normally go missing. This is how people get exfiltrated. It reeks of classic espionage tradecraft, whether voluntary or coerced.

Third, the Frontier Science Cluster. 

The list is heavily weighted toward people working on the absolute edge of science and defense. Amy Eskridge with her “exotic” propulsion research. Monica Reza, a superalloy inventor for rocket engines. Nuno Loureiro in nuclear fusion. Maj. Gen. McCasland overseeing the Pentagon’s most advanced work in hypersonics and directed energy weapons. These aren’t just scientists; they are scientists building the next generation of power.

Not every case is a mystery. The tragic murders of Nuno Loureiro and Carl Grillmair were solved by conventional police work. Jason Thomas’s death appears to be a sad, personal matter. But these explainable cases don’t disprove the pattern. They sharpen it. They serve as a control group, highlighting just how profoundly strange the other eight cases truly are.

Not everyone is convinced of a conspiracy. Officials from NASA have stated that “nothing related to NASA indicates a national security threat at this time.” Some family members of the deceased have pointed to pre-existing medical conditions or personal struggles, urging the public not to jump to conclusions. It’s a classic case of a mystery with too many variables and not enough answers.

The Theories: From Foreign Spies to Tragic Coincidence

With a list like that, speculation is running wild. The theories generally fall into three buckets.

A Coordinated Foreign Attack 

This is the “spy thriller” scenario. The idea is that a foreign power is systematically targeting key U.S. scientific personnel to steal secrets, slow down progress, or create chaos. Some of the scientists were working on technologies directly related to planetary defense and advanced propulsion—fields where companies like SpaceX and Blue Origin are racing ahead with major national security contracts.

A Pattern of Personal Tragedy

 

This is the more grounded, and perhaps more heartbreaking, explanation. These are high-stress, high-stakes jobs. Several families have pointed to pre-existing health problems or severe personal struggles. It’s entirely possible, some experts argue, that this is just a tragic statistical cluster—a series of unconnected events that look like a pattern simply because we’re looking for one.

Something In-Between

 

Could it be something other than a state actor? Corporate espionage? A rogue group trying to acquire technology? The truth is, we don’t know. The range of possibilities is massive.

For every compelling detail suggesting a conspiracy, there’s a counter-detail pointing to a simpler, more personal explanation. The factory-reset phones are strange. But so is the grief of a man who just lost both parents. The concentration of cases in New Mexico is suspicious. But it’s also a hub for national labs.

Right now, the only certainty is uncertainty. As these brilliant minds are silenced one by one, the questions only get louder. The official investigations will hopefully provide clarity, but until then, we’re left with a deeply disturbing puzzle. It’s a stark reminder that in the world of cutting-edge science and national security, the stakes are unimaginably high.

The Wall of Silence

The official response is a study in contradiction. FBI Director Kash Patel says the bureau is “spearheading the effort to look for connections.” House Oversight Chairman James Comer launched a formal inquiry, calling the pattern a potential “grave threat to U.S. national security” and raising the possibility of a “foreign operation.” President Trump himself called it “pretty serious stuff.”

And then comes the institutional denial.

NASA issued a statement saying that “nothing related to NASA indicates a national security threat.” The Department of Defense says it has “no active national security investigations” into any of the individuals.

We’ve seen this script before. In the 1980s, around 25 British scientists working for GEC-Marconi—a key contractor on the “Star Wars” Strategic Defense Initiative—died in a string of bizarre suicides and accidents. The official government inquiry found no connection. Just a lot of stressed-out guys having bad luck. The public never bought it. Then, as now, the explanation felt thinner than the facts it was supposed to cover.

The problem isn’t the lack of information. It’s the abundance of coincidence. A tweet from the future. A shooter from JPL. A dozen dead and missing scientists working on rockets, nukes, and space. And a government investigation that runs parallel to a campaign of official denial. The FBI says it’s searching for a pattern. The pattern is right there. A shooter from Caltech. The dead and missing from JPL. The nuclear experts who walked out of their lives in New Mexico. The problem isn’t that nobody knows what’s going on.

The problem is that the people who do aren’t talking.
