A former FBI agent has advanced a startling theory about the mysterious death of a Los Alamos National Laboratory employee, suggesting that advanced directed energy weapons and psychological manipulation technology may have played a role in the nuclear scientist’s mysterious disappearance and death.
The explosive claims add a new dimension to a growing series of suspicious deaths and disappearances involving individuals connected to sensitive nuclear, aerospace, and classified government programs.
Melissa Casias, a 53-year-old employee at the prestigious Los Alamos National Laboratory, vanished under highly unusual circumstances on June 26, 2025.
Nearly a year later, her skeletal remains were discovered in New Mexico’s Carson National Forest, raising more questions than answers.
Now, former FBI agent Ben Hansen believes the evidence points strongly toward foul play.
Strange Behavior Raises Red Flags
Casias disappeared after dropping off her husband, a laboratory superintendent, at work.
What happened next baffled both investigators and her family.
According to reports, Casias falsely claimed she needed to retrieve a forgotten security badge despite already having it in her possession.
She then visited her daughter, dropped off a sandwich, said she would be working from home, returned to her residence, wiped data from both cell phones, and left without taking her purse, identification, keys, or other personal belongings.
Surveillance footage later captured her walking alone along State Road 518 near Ranchos de Taos.
It was the last confirmed sighting of her alive.
When her remains were found months later, investigators also discovered a handgun nearby that family members insist did not belong to her.
Authorities have yet to determine an official cause of death.
New Mexico State Police confirmed that forensic scans found no projectiles inside the reconstructed skull.
For Hansen, that fact is significant.
“Just what they have shared is highly, highly suspicious,” Hansen said.
“I don’t know if I give a percentage, but it’s kind of more like an 80 percent foul play versus someone who’s depressed is the way I see it.”
Directed Energy Weapon Theory Emerges
Hansen suggested that advanced directed energy technologies could potentially explain both Casias’s strange behavior before her disappearance and the lack of conventional evidence at the scene.
He pointed to emerging technologies capable of emitting microwave radiation, charged particle beams, and so-called “voice-to-skull” systems that allegedly project sounds or voices directly into a target’s mind.
According to Hansen, such technologies could theoretically create confusion, paranoia, fear, or the perception that a victim is receiving instructions from an external authority.
Low-frequency sound waves have also been studied for their potential psychological effects, including inducing anxiety, panic, and feelings of being watched.
“These effects mirror many of the symptoms reported in Havana Syndrome cases,” Hansen noted, referring to the mysterious neurological incidents reported by U.S. diplomats and intelligence personnel around the world.
“Homeland Security actually purchased one from the black market, something similar, a small device, it seems like that maybe Russia had,” Hansen said.
“And if that is possible, is it possible that foreign adversaries are targeting U.S. military or contractors and employees for some other new sort of a weapon of some sort?”
Hansen stopped short of claiming directed energy technology was definitely involved, but said outside influence could help explain Casias’s otherwise inexplicable actions.
“I think either there was an influence from the outside, and I’m not saying that it’s energy-directed anything, but foreign adversary influence of some sort,” Hansen said.
“The other option is they were enticed.
“This is the behavior in all these cases; it looks like they thought they were coming back.”
WATCH:
Part of a Larger Pattern
The theory arrives amid mounting concerns over a growing number of deaths and disappearances involving scientists, engineers, military personnel, and researchers connected to highly sensitive government programs.
Observers have pointed to a string of cases involving individuals tied to nuclear technology, advanced propulsion systems, classified aerospace projects, and UFO/UAP research.
Among the most notable was the disappearance of retired Air Force Maj. Gen. William Neil McCasland, who oversaw highly classified space and aerospace programs.
His disappearance came shortly after President Donald Trump ordered the release of previously classified UFO and UAP records.
By spring 2026, reports had documented multiple deaths and disappearances involving aerospace engineers, NASA scientists, nuclear specialists, and researchers linked to advanced technologies.
Many of the cases were officially ruled accidents or suicides, but critics have highlighted recurring red flags including erased electronic devices, unusual behavior before death, abrupt departures, and unexplained circumstances.
Anti-Gravity Researcher Made Similar Claims
Adding another layer to the mystery, anti-gravity researcher Amy Eskridge reportedly warned before her death that she was being targeted by directed energy attacks.
Eskridge, co-founder of the Institute for Exotic Science in Huntsville, Alabama, claimed she suffered burns, skin lesions, and other symptoms she believed were caused by microwave-style attacks.
She reportedly told associates she feared for her safety while preparing to discuss advanced propulsion technologies and research connected to UFO-related topics.
Retired British intelligence officer Franc Milburn later investigated her allegations and concluded that efforts may have been made to intimidate or disable her.
Now, Hansen’s theory is drawing renewed attention to those earlier claims.
Investigation Continues
At this stage, authorities have not concluded that directed energy weapons played any role in Casias’s death.
The medical examiner has yet to release an official cause of death, and investigators have not announced any suspects.
Nevertheless, Hansen’s comments are likely to intensify scrutiny surrounding a case already filled with unanswered questions.
With a Los Alamos employee behaving in ways her family says were completely out of character, her phones mysteriously wiped, no clear cause of death established, and an unfamiliar handgun discovered beside her remains, many believe the case is far from resolved.
As more questions emerge about the deaths and disappearances of individuals connected to highly sensitive government programs, calls for answers continue to grow.
