Why Are US Scientists Going ‘Missing’? A Look at the Growing List of ‘Unexplained’ Deaths and Disappearances

A series of deaths and disappearances involving American scientists and prominent figures within the Ufology community has sparked intense public interest and calls for federal investigation. Concerns have intensified following reports regarding the death of prominent UFO researcher and author David Wilcock, whose passing in Colorado has fueled speculation about a broader pattern of suspicious incidents.

David Wilcock, a 53-year-old author and researcher known for his extensive work on extraterrestrial (alien) life, ancient prophecies, and New Age spirituality, was confirmed dead following an incident in Boulder County, Colorado. According to local law enforcement, deputies responded to a residence on April 20, 2026, following reports of a mental health crisis. Authorities stated that an individual at the scene took his own life. While the identity was not immediately released by officials, the news was later confirmed by U.S. Representative Anna Paulina Luna.

Wilcock’s death follows a string of recent losses in the paranormal and Ufology community, including the passing of British UFO researcher Nick Pope and Swiss author Erich von Däniken earlier this year. The proximity of these deaths has led to widespread social media speculation regarding potential foul play, despite the lack of official evidence linking the events.

US Scientist Deaths: Federal Inquiry Launched

The conversation surrounding Wilcock’s death has converged with long-standing, viral speculation concerning the deaths and disappearances of 11 American scientists. These individuals, reportedly involved in sensitive research within aerospace, nuclear, and defense-related fields, have been the subject of persistent online theories suggesting they were targeted due to their work.

Recent reports indicate that federal authorities, including the FBI, have begun examining these cases to determine if there is any connection between them. While conspiracy theories often frame these deaths as part of a clandestine effort to suppress scientific advancements or government secrets, official investigations have largely pointed toward individual circumstances, such as health issues or personal crises.

The following individuals, all associated with high-level research, defense, or scientific institutions, have been reported missing or have died under circumstances that remain subject to investigation. Amy Eskridge ‘Suicide’: UFO Scientist’s Death Part of Federal Probe Into 11 ‘Mysterious Cases’.

Cases of Missing Individuals

• William Neil McCasland: A retired Air Force General and former commander of the Air Force Research Laboratory. He disappeared from his New Mexico residence on February 27, 2026. While his personal belongings remained behind, he reportedly took a firearm with him.
• Monica Jacinto Reza: A former Technical Fellow at Aerojet Rocketdyne and senior aerospace engineer. She was last seen on June 22, 2025, while hiking the Mount Waterman Trail in California.
• Steven Garcia: A government contractor specialized in non-nuclear components for nuclear weapons. He left his home in New Mexico on foot in August 2025 and has not been seen since.
• Anthony Chavez: A former employee at Los Alamos National Laboratory. He went missing on May 8, 2025, leaving his vehicle, keys, and wallet at his residence.
• Melissa Casias: An administrative secretary at Los Alamos National Laboratory who held high-level security clearance. She vanished on June 26, 2025, after returning to her home to work remotely.

US Scientist Deaths Under Investigation or Unclear Circumstances

• Nuno Loureiro: The director of the Plasma Science and Fusion Center and a prominent MIT nuclear physicist. He was fatally shot inside his home in December 2025.
• Carl Grillmair: A Caltech astrophysicist and NASA-affiliated researcher known for his work in galactic structures and asteroid tracking. He was killed by gunfire on his front porch on February 16, 2026.
• Frank Maiwald: A principal researcher at NASA’s Jet Propulsion Laboratory (JPL). Following his death on July 4, 2024, investigators highlighted the absence of a public autopsy or a clear cause of death.
• Michael David Hicks: A NASA JPL scientist who contributed to the DART asteroid deflection project. He died in July 2023. While some sources cite natural causes, his name has been linked to broader investigations concerning "missing or dead" scientists.
• Jason Thomas: An assistant director of chemical biology at Novartis. Reported missing in December 2025, his body was subsequently discovered in a Massachusetts lake in March 2026.

The latest name to resurface in the context of these broader inquiries is Amy Eskridge, a Huntsville-based UFO researcher whose 2022 death has become a focal point for those questioning the safety of scientists in "exotic" fields.

The term "11 US Scientists Missing or Dead" has become a recurring headline in online discourse, often amplified by media outlets covering viral social trends. These narratives frequently merge the deaths of credentialed scientists with the sudden passing of high-profile figures in the "disclosure movement" - those who advocate for government transparency regarding Unidentified Anomalous Phenomena (UAP).

Despite the intense scrutiny and the demand for a comprehensive federal probe, authorities urge caution against drawing conclusions based on correlation alone. As of now, investigators continue to treat these incidents as separate events, with the FBI’s involvement focused on determining whether any common threads - such as foreign interference or industrial espionage - exist among the cases of the scientists under review.

For now, the intersection of high-profile deaths in the UFO community and the mysterious circumstances surrounding certain scientific personnel remains a focal point of intense public speculation, awaiting further clarification from official federal sources.
