A growing number of unexplained deaths and disappearances involving U.S. scientists and military personnel has prompted a congressional call for federal intervention. The latest development comes as Representative Eric Burlison (R-MO) has requested FBI involvement in the cases, citing concerns over potential connections between the incidents.
Part 1: Immediate Action & Core Facts
Two Key Developments:
Congressional Demand for FBI Investigation: Representative Eric Burlison (R-MO) has formally requested FBI assistance in probing the disappearances of retired Air Force Major General William Neil McCasland and aerospace engineer Monica Reza, as well as other unexplained cases. Burlison cited the suspicious nature of McCasland's disappearance—including his unexplained absence from his home—and Reza's vanishing while hiking.
Unsolved Cases Involving Scientists: At least eight scientists or lab employees linked to sensitive U.S. research have died or gone missing since July 2024. Among them are NASA researcher Frank Maiwald, whose death remains unexplained, and Los Alamos National Laboratory retiree Anthony Chavez, who vanished in May 2025. Neither case has yielded public updates.
Part 2: Deeper Dive & Context
Background on the Cases
Frank Maiwald (NASA): The 61-year-old NASA scientist, who worked on advanced satellite technology and life-detection projects, died on July 4, 2024. No autopsy was performed, and NASA has not publicly commented on his death. His obituary remains the only official record of his passing.
Anthony Chavez (Los Alamos): The 79-year-old retired lab employee disappeared on May 4, 2025. The Los Alamos Police Department confirmed the search is ongoing, with no new leads after nearly a year.
William Neil McCasland (Retired Air Force General): McCasland, who held senior roles in U.S. Air Force science and space research, was last seen on February 27, 2025. His disappearance has drawn attention due to his alleged knowledge of UFO-related research and his prior oversight of Reza's government-funded rocket materials project.
Monica Reza (Aerospace Engineer): Reza vanished while hiking months before McCasland's disappearance. She had worked on a project overseen by McCasland, though authorities have not confirmed a direct link between the cases.
Official Responses and Investigations
FBI Involvement: Burlison has also requested FBI scrutiny into the "suspicious suicide" of another individual linked to whistleblowers David Grusch and Jake Barber. The FBI has not publicly confirmed its involvement in any of these cases.
Law Enforcement Statements: The Bernalillo County Sheriff's Department is investigating McCasland's disappearance but has not established a connection to other cases. The Los Alamos Police Department continues to search for Chavez without new information.
Broader Implications
The lack of public updates and official transparency has fueled speculation about potential security risks or foul play. Burlison's call for FBI intervention underscores growing concerns over the safety of personnel involved in sensitive research. However, authorities have not provided evidence of a coordinated threat or pattern linking the cases.
