Once is an accident. Twice is a coincidence. Three times is a pattern. Six is probably leaning closer to what should be considered a national emergency. The count of missing or dead UFO researchers and scientists with sensitive American information is now at six.
Missing UFO researchers and murdered scientists: The Five We Knew About
Retired Major General Neil McCasland was not just any general. He oversaw the Air Force’s $2.2 billion science and technology program at Wright-Patterson Air Force Base, was considered one of the military’s leading experts on UFOs, and was named in the 2016 Wikileaks emails as an advisor to Tom DeLonge when DeLonge was building his UFO disclosure organization To the Stars Academy.
On February 27th he walked out of his home in New Mexico and vanished without a trace. He left behind his phone, his wearable devices, and his prescription glasses. Clothing was found near his home. He has not been seen since. The man knew things. Where he is, nobody can say.
Aerospace engineer Monica Jacinto Reza was the co-inventor of a rocket alloy called Mondaloy and the Director of the Materials Processing Group at NASA’s Jet Propulsion Laboratory. She vanished while hiking in the Southwest in 2025 and her case remains unsolved.
Reza worked directly within the program McCasland oversaw. Both figures from the same Air Force Research Laboratory. Both gone during hiking trips in the Southwest. Both without explanation. Reza disappeared just four days before Melissa Casias, which we will get to in a moment.
Within the same general window, three other scientists were killed.
Nuno Loureiro, 47, director of the Plasma Science and Fusion Center at MIT, was assassinated at his home in Brookline, Massachusetts on December 15th, 2025. He was reportedly on the verge of a breakthrough in nuclear fusion that could have produced unlimited clean energy and ended fossil fuel dependence as we know it.
Carl Grillmair, 67, a Caltech astrophysicist whose work contributed to the discovery of water on a distant planet and whose colleagues called potentially significant for identifying signs of life within 160 light-years of Earth, was shot and killed on his front porch at six in the morning on February 16th, 2026.
Jason Thomas, 45, a chemical biologist whose research focused on developing new medicines including potential cancer treatments and who had active contracts with the Department of Defense through Novartis, was found dead near a lake in Wakefield, Massachusetts on March 17th.
That was five. Then there is a sixth.

Melissa Casias, 54, was an administrative assistant at Los Alamos National Laboratory, the facility founded during the Manhattan Project that has been tied to nuclear weapons research ever since.
She has not been seen since June 26th, 2025.
Her family says she uncharacteristically decided to work from home that day, but she was last spotted miles from her house walking alone without her wallet, her phone, or her keys. Both of her phones were later found at home wiped completely clean after someone performed a factory reset on them.
The timeline of her last day is strange in ways that are hard to explain away. She dropped her husband Mark off at LANL that morning, where he works as a superintendent. Their daughter says Casias then stopped by her workplace to drop off a sandwich and told her she was heading home to grab her security badge she had forgotten.
She never showed up to work. Her supervisor confirmed she never worked from home that day either. Then she simply ceased to exist, on foot, in the desert of the southwestern United States, with nothing in her pockets.
This day in age, it’s really difficult to just go missing, ya know?
What Connects Them
Casias went missing just four days after Monica Reza vanished. Both women had worked at facilities with documented ties to McCasland. Five of the six people in this cluster had ties to nuclear research or missile technology. Four of them can now be shown to have direct connections to each other.
Think about how difficult it actually is to disappear in 2025. Every step you take can be tracked. Every transaction leaves a trail. Security cameras cover nearly every square inch of civilization. Most people do not walk to their mailbox without their phone. Melissa Casias walked miles through the desert with empty pockets and a head full of classified information from one of the most sensitive research facilities on earth and was never seen again.
To be fair, there has been reporting that she was in financial difficulty and it is possible she chose to disappear on her own. But why the strange detour to her daughter’s workplace? Why the story about forgetting her badge? Why were both phones factory reset? People who want to leave their lives do not usually build a two-hour alibi trail before vanishing on foot into the desert.
Look, I really don’t want to speculate, but when six people with classified security clearances working on projects tied to nuclear weapons, advanced propulsion, plasma fusion, astrophysics, and aerospace engineering, all with overlapping institutional connections, we deserve more than a couple of local news segments and a tweet from a congressman.
Six. Pay attention.
