At least 10 people tied to sensitive US research have died or disappeared

Last time I looked into this (last week, I think) it was a big wad of nothing. The people had disappeared over a span of many years. They weren't tied to any particular program, employer, or even any particular area of study, just “uh, tech stuff”. Some of them were technical experts, some weren't; one was an administrative assistant. One was killed by a campus shooter who also killed two students.

Typical example: “In the years since, several others connected to JPL have also died or disappeared: Frank Maiwald, a specialist in space research, died in Los Angeles in 2024 at 61.”

cyanydeez•1h ago
Yeah, it's like "At least 10 people with a red sweater on Tuesday have gone missing".

Or stupider: At least 10 people flipped a coin and it ended up on Heads!

The fact that it reached CNN levels of stupid means journalism is part of the overall USA's intentional brain drain.

mjd•1h ago
It's worse than that, it's 11 people who wore sweaters in various shades of red, orange, and pink, at some point in the past ten years.

“Anthony Chavez, 79, worked at Los Alamos National Laboratory until he retired in 2017. He reportedly disappeared on May 8, 2025.”

4 separate government agencies are putting time and effort into something.

The headline is accurate. The reporting is accurate.

Should CNN not report what the government is doing?

Or are you confused and assume that the investigation has returned and finding? Or maybe, we should highlight the things the government is doing.

Why do you find what the article is saying sane?

wat10000•1h ago
If the weather service starts an investigation into Tuesday’s rain shower, that should be reported. But if that rain shower was completely within the normal range of weather for that location and time of year, that should also be part of the reporting. This article takes everything from the government at face value.

I need to see stats on how many would be expected to die or disappear from natural causes and I’m never seeing that on these stories. Weird things happen all the time to people in any field of work, it’s only concerning if this is rising above the natural noise. The fact that the current administration, which has proven time and time again it is ignorant about statistics and pretty much all things science, is raising the alarm does not bode well for this being an actual issue.

Via [0], "Well, there are about 2 million researchers in the US. There are about 25 deaths per million people per day in the US, that’s 50 scientists dying each day, or 73,000 scientists over a four year period. Finding 11 that have some vague connection does not seem unusual to me."

That's not the same age range as actively practicing researchers.

notahacker•41m ago
But then if we're doing age ranges, the 10 people "tied to sensitive research" who have disappeared or died are 59, 61, 60, 68, 53, 60, 78, 47, 67, 39 (with the two youngest identified as homicide and suicide). How does a cohort with an average age in their 60s compare with the age range of actively practising researchers?

Michael Hastings was on DMT, smoking weed, and having a manic episode. His family was so worried about his erratic behavior that his brother had flown out to try to get him to check into rehab.. His brother met with Michael the day before he died and realized he was going to need more help, so he called his other brother to fly to LA to try to convince Michael to go to rehab or check into an inpatient psych ward. Michael snuck out in the middle of the night while they were waiting for their other brother and crashed his car into a tree.

In his brother's own words, "I really rule out foul play entirely. I might have been suspicious if I hadn't been with him the day before he died. After all, he definitely was investigating and writing about a lot of sensitive subjects. But based on being with him and talking to people who were worried about him in the weeks leading up to his death, and being around him when he had had similar problems when he was younger, I was pretty much convinced that he wasn't in danger from any outside agency."

It's an exceptionally dumb conspiracy theory among many other exceptionally dumb ones.

Unless that agency is a mob culture who manifests as the voices in our heads.

Remember those navy seals who were murdered by schizophrenic brothers of girlfriends?

Look into all the research of “voices in our heads.” And I’m sure you’re impressed by how well “gang stalking” and “targeted persons” is handled. Crazy crackpot schizophrenic conspiracy theories. And signs of a truly diabolical secret war upon us all.

I know, take meds and get help. That’s the byline of those who consider themselves sane.

“They”? You act like those disorganized persons have similar backgrounds or training.

I was gang stalked for years before being “press ganged” into a hooligan army or Power. I know Americas secrets, you just won’t listen. Like Cassandra, such are the most genuine prognostications among the incredulous.

The crazy people are those driven crazy. Look for those stories where otherwise normal people were “gaydon”. That where random people pretend the subject is “gay” even though they are not. Those sad people sometimes shoot up gaybars or gaybash because “they have the devil inside them.”

The “true” conspiracy of conspiracies is that we are not alone in our own minds and entire subcultures are dedicated to screwing with us. Everything these unfortunate peoples experience is sheer insanity. Their mental illness is cultivated.

And if you don’t “believe in” extra sensory perception (more apt term than the alternatives), then why do you know what “gaydar” is? Manipulating the sexuality of others (gender dysphoria) are among the games these so empowered love to play.

Hidden within the silliest things are occult secrets belying an unnatural order among us.

This BBC article https://www.bbc.com/news/articles/cwyw9rpdl4po also has this tidbit:

> "The US Top Secret-cleared aerospace and nuclear workforce is ~700,000 people," science writer, investigator and pseudoscience debunker Mick West wrote on 16 April on his Substack.

> "Ordinary mortality over 22 months predicts ~4,000 deaths, ~70 homicides, and ~180 suicides. The list has 10 … The deaths are real. The families' grief is real. The pattern is not."

Unfortunately, this is a sign of the times we live in now. Nobody extends a little grace to others. They assume every act is an intentional slight.

There's no room for mistakes or even differences of opinions, and it's tearing us apart.

Part of it, I think, comes from the anonymous nature of online communications, and little to no ramifications to bad behavior. It's the end result of "I can do whatever I want, the established rules and societal norms don't apply anymore."

jasonlotito•1h ago
> The FBI now says it “is spearheading the effort to look for connections into the missing and deceased scientists,” adding that it “is working with the Department of Energy, Department of War, and with our state … and local law enforcement partners to find answers.”

> Separately, the Republican-led House Oversight Committee announced Monday it will investigate ...

So, do we not want the news reporting what the government is doing? That's the FBI, DoE, DoD, and the House Oversight Committee putting effort into this.

Like, no, i want this reported, not because there is anything that will come from it, but because we should report one what the government is doing.

Why do you think CNN should NOT report one what the government does?

walletdrainer•48m ago
You can report these stories without sanewashing.
OutOfHere•1h ago
The critical thinking skills you need are that they were connected to nuclear research. UFO is a distraction. The purpose of the investigation is to determine whether the deaths are connected.
wat10000•1h ago
The critical thinking skills you need are the understanding that people die sometimes, and the question is how it compares to the normal rate of death among this population.
notahacker•50m ago
And not just rates, but also how they died and whether malicious actors were particularly likely to bother about disappearing them in ways which are actually really much harder to stage than happen naturally like disappearing someone trailwalking in mountains with friends, or whether someone so incompetent they were arrested on the retired professor's property a couple of months before he was shot and then caught still driving a car full of the victim's stuff after the murder was discovered is particularly likely to be part of a big cover up.

An disappearance of a retired major general without his personal possessions and someone committing suicide whilst due to testify in court, sure those things warrant an investigation even though those things happen as the result of mundane crime or mental breakdowns as well as conspiracy. But another thing entirely for the "nothing much to see in those Epstein files" FBI to spin the grand narrative that connecting all these dots is a legitimate question because UFOlogists on YouTube.

petre•50m ago
Maybe he wants to frame it as the scientists being abduced by aliens. We now know that the whole UFO narrative of the 90s was a government psy ops to distract people from stealth fighter testing and dismiss the sightings as 'aliens'.
jdw64•1h ago
I think this is a case of flawed human pattern recognition.

Even in the article, it lumps everything together as “in recent years,” but over the span of several years, people across a large country can die for all sorts of unrelated reasons. That’s just how basic mortality statistics work.

Also, the category “scientists” is far too broad. Unless we’re talking about the same organization, the same field of research, and the same timeframe, it’s hard to justify treating these cases as connected. The scope is too wide and the professions too varied. It feels like people are constructing conspiracy theories out of weak patterns because those narratives are more stimulating.

If we applied the same logic, we could take annual industrial accident deaths in the U.S. and claim they’re part of some coordinated assassination plan by capitalists. That obviously doesn’t make sense. (Although, to be fair, one could argue that industrial accidents reflect structural issues tied to capital, but that’s a different kind of argument entirely.)

What I’m really trying to say is that this kind of article feels like a product of the internet’s incentive structure — framing loosely related events as something suspicious in order to attract clicks and attention.

OutOfHere•1h ago
They have a distinct commonality of nuclear research. As such, is the limitation in pattern recognition not yours? If you are overlooking it, you are suppressing it, and are a a part of the conspiracy.
jdw64•1h ago
From what I’ve looked up, the range is actually quite broad from astrophysics to aerospace to administrative roles.

Here are the individuals mentioned:

* Michael David Hicks (JPL, comets/asteroids research) * Frank Maiwald (space research / JPL) * Monica Reza (aerospace engineer, JPL) * Nuno F.G. Loureiro (MIT, nuclear science and fusion) * Carl Grillmair (Caltech astrophysicist) * William Neil McCasland (Air Force, aerospace research) * Melissa Casias (Los Alamos National Laboratory, administrative role) * Anthony Chavez (Los Alamos, construction foreman)

I’m not sure what standard is being used to claim a meaningful connection here. The category seems extremely broad.

And the idea that “if you question it, you’re part of the conspiracy” is pretty convenient reasoning.

Honestly, I’d love to be part of some shadow organization secretly running the United States from behind the scenes — do you think they’re accepting applications?

OutOfHere•1h ago
For the record, an administrative worker can have access to substantial sensitive intelligence. Construction workers can know the physical details of facilities. Both are a rich target for a foreign intelligence to exploit. I am not claiming that anything of the sort happened, but it merits investigation.
jdw64•1h ago
First, sorry for the earlier sarcasm.

I agree that people in administrative or support roles can still have access to sensitive information and could, in theory, be targets.

But that still defines a very large group. If we include anyone with potential access across different institutions, roles, and locations, then it becomes easy to see patterns in what could simply be unrelated cases.

The key question is whether there is any concrete overlap — same organization, same project, same timeframe, or any shared operational detail. Without that, it feels more like a pattern being inferred after the fact than evidence of a coordinated connection.

More broadly, if we make the category of “possible targets” to wide, it stops meaning much. The default assumption should be that these are unrelated events, unless there’s clear evidence tying them together. Simply saying they could be targets does't really change that.

odyssey7•1h ago
I think this is an interesting pattern, but I see your point. The network effects of ~people a degree removed from direct nuclear research~ gets big.
b9apratus•1h ago
Yes. Rape or murder a woman or child and you may receive an invitation.

American Thought Control and thought controlled Americans human sacrifice of the innocent to pay for their “Power.”

From the Satanic sacrifices of the 80s/90s, through the public shootings of the 2000s, to the rise of white nationalism and everything that stands for today, the occult shadow governance pervades all, for they have the ultimate Power to travel among and act as God in the minds of the vulnerable and unsuspecting.

It is a mob culture, with hierarchies who can hear every thought and memory in the human mind, not an organized cabal of rich wealthy people using encrypted chat.

And they do these things to control the narrative and prune dissent.

codechicago277•56m ago
Conspiracy theories are a natural way to try to make sense of a chaotic and confusing world where the government has shown a pattern of lying to its citizens. Unfortunately, the theories oversimplify, find patterns where they don’t exist, and almost always melt away when looked at critically (see the Michael Hastings commentary above).

The mistrust in the government is well founded, as Snowden, CIA secret operations in the Cold War, Abu Gharib, etc. have shown. But conspiracy theories fully embrace the nihilistic view that truth is unknowable, everything is evil, and other people have far more power than is actually realistic.

At some point it becomes a literal mental disease, and if you truly believe what you’ve written you should seek help. QAnon and pizzagate are creations of internet trolls on 8chan who lie to the vulnerable to gain their own little power.

The NameUs US public database of around 26k longer term active missing person cases adds around 600 new names per month. It doesn't seem odd that a handful over years would share a narrow professional interest.

But that number, 20 disappeared people per day, is gut wrenching. (US murders are at around 40 per day.) Surveillance sucks, but maybe at least it can be leveraged to find patterns when married to NameUs data. On the other hand I can sympathize with someone who just doesn't want to be found.

esseph•58m ago

No.

spacephysics•45m ago
I’d slightly disagree, the profile of people who go missing is as important as a random chance there is a coincidence. Former military officers, high-level scientists. These individuals have training, money, and live in areas where this tends not to happen.

A disappearance of someone from the above background, vs someone who is say in midwest rural America or near areas where human trafficking crimes occur at a higher rate than normal, matters.

Further, their research/knowledge of sensitive government material also implies they likely have some form of overwatch or at least minimal monitoring for foreign agent threats from our government (or had in the past). Its not uncommon for high ranking military officials to have some form of training in counter surveillance tradecraft for this exact reason.

The odds these events are due to a foreign adversary given the multiple wars and geopolitical tensions are not negligible

From my personal experience, these are also the kinds of people that enjoy challenging and thrill seeking hobbies like mountain climbing, backpacking, etc that put them in a position where there’s some not insignificant chance of death in a remote location.

I'll happily take 20 missing people per day in exchange for the ability to organize a demonstration[0] or an uprising when needed and for not being disappeared myself when the surveillance net falls into the hands of the next (or current) despot.

Three things:

1. Many people intuitively assume that clumping/clustering of events implies non-randomness, and that random processes are smooth and low-variance. The opposite is true [1].

2. A consequence of 1. is that people often over-estimate their understanding of the likelihood of events and the degree to which they are conditional.

3. There was an intriguing comment on this site a few days ago [2], referencing Daniel Kahneman work on System 1 and System 2 thinking. From memory it said that reality is a lot less explicable than we tend to think - and that a lot of what we casually think we know about the everyday world is just our brains filling in the gaps using quick and cheap System 1.

As to why people are clutching at science-fictional interpretations: perhaps they're looking for some excitement or novelty? That would be very human.

I think what someone needs to do is before looking up these names or professions, first define a the category of "sensitive US research" well enough (specific institutions, areas, level of access, seniority, etc) and only after that look at history to total missing persons and then decide if there is more or less of them missing in proportion to the total.
