The Federal Bureau of Investigation is now leading a review of at least 10 deaths and disappearances involving scientists and government workers tied to sensitive U.S. research, including four with Southern California links. (nbcnews.com) NBC Los Angeles reported April 21 that the Southern California cases include former Jet Propulsion Laboratory scientist Michael David Hicks, who died July 30, 2023, at 59; Jet Propulsion Laboratory researcher Frank Maiwald, who died July 4, 2024, at 61; Jet Propulsion Laboratory scientist Monica Reza, who vanished on a hike near Mount Waterman on June 22, 2025, at 60; and Caltech astrophysicist Carl Grillmair, who was shot to death in Llano in February 2026 at 67. (nbclosangeles.com) The FBI said April 20 that it would work with the Department of Energy, the Department of War, and state and local law-enforcement agencies to look for any connection among the cases, which stretch back to 2022. The House Oversight Committee also said it wants briefings from the Defense Department, Energy Department, FBI and NASA. (nbcnews.com) The inquiry has drawn federal attention because several of the people worked around nuclear, aerospace or other restricted programs, even though officials have not publicly established a single cause or common plot. NASA said it is cooperating but added that, so far, nothing tied to the agency indicates a national-security threat. (cbsnews.com, nbcnews.com) That distinction matters in Southern California because two of the four local names were Jet Propulsion Laboratory researchers, one was a Caltech astrophysicist, and the cases themselves do not line up neatly: two deaths were publicly reported without causes, one case is a missing-person investigation, and one is a homicide with an arrest. (nbclosangeles.com, foxla.com) In Monica Reza’s case, the Los Angeles County Sheriff’s Department said she was last seen around 9:10 a.m. on June 22, 2025, near the 6000-foot day-use parking area on Angeles Crest Highway. Her disappearance has received new scrutiny as the broader federal review has expanded. (yahoo.com, solvethecase.org) In Carl Grillmair’s case, Los Angeles County sheriff’s deputies found him with a gunshot wound on the porch of his Llano home in February, and prosecutors later charged Freddy Snyder with murder. ABC7 reported detectives do not believe the two men knew each other, and no motive had been released. (abc7.com, foxla.com) For Hicks and Maiwald, the public record is thinner. Hicks’ memorials say he worked at Jet Propulsion Laboratory from 1998 to 2022 and died at 59 on July 30, 2023, while Maiwald’s obituary says he died in Los Angeles on July 4, 2024, at 61; neither source listed a cause of death. (lpl.arizona.edu, legacy.com) President Donald Trump said last week that he had been briefed on the cases and expected more answers soon, while federal officials have kept emphasizing that the review is looking for links, not announcing one. For now, the central fact is narrower than the speculation: investigators are treating the cluster as serious enough to examine together. (nbcnews.com, mynewsla.com)
