MYSTERY: Another official tied to America’s scientific secrets vanishes… see the alarming web linking six mysterious deaths and disappearances

From the Daily Mail: The case of a New Mexico mother who vanished without a trace last year has now been connected to the mysterious deaths and disappearances of five other key scientists and defense officials throughout the US.

Melissa Casias has not been seen since June 26, 2025, when her family said she uncharacteristically decided to work from home, but was last spotted miles from their house walking alone without her wallet, phone or keys.

Casias, 54, was an administrative assistant at Los Alamos National Laboratory (LANL), a facility founded by the famed Manhattan Project during World War II. It has been tied to nuclear weapons research ever since.

Her disappearance takes the number of people from the scientific community potentially holding highly sensitive secrets who have gone missing or died since June 2025 to six.

Of those six, five had ties to nuclear research or missile technology and four of them can now be shown to have some type of connection to each other.

NASA scientist Monica Reza, 60, mysteriously disappeared while hiking with friends on the morning of June 22, 2025, in the Angeles National Forest. Two friends saw Reza just 30 feet away while they were hiking. When they looked back, she was gone, without a trace.

Just four days later, on June 26, 2025, Casias vanished.

Casias’s daughter, Sierra, had told investigators that her mother came to the teen’s place of work to drop off a sandwich, and said she was going back home to pick up her security badge needed to enter her place of work at LANL.

However, Casias’s supervisor said she never showed up for work that day. Instead, the case takes a more disturbing turn. The Daily Mail wrote:

When Casias’s family returned home, they found that only her work and personal phones had been left behind and wiped clean after someone performed a factory reset on them.

Surveillance cameras last spotted Casias walking alone eastward on State Road 518, roughly three miles from her home, around 2.20pm local time. No body or any definitive evidence of her whereabouts has been found since.

Both Reza and Casias had worked at facilities linked to retired Air Force General William Neil McCasland, who later also vanished near a hiking trail in Albuquerque, New Mexico, on February 27, 2026.  He reportedly left his phone, prescription glasses and smart devices behind in his New Mexico home, but took with him a pair of boots and his .38-caliber revolver.

Three other scientists have been found dead:

• • • Nuno Loureiro, who was working on breakthroughs using nuclear fusion as an energy source, was shot dead in his Brookline home on December 16, 2025.
    • Astrophysicist Carl Grillmair, 67, was killed at his home on February 16, 2026, after being shot on his front porch around 6am local time.
    • Jason Thomas, a pharmaceutical researcher at Novartis, was found dead in a Wakefield lake on March 17, 2026 after disappearing without a trace three months earlier.
