Disappearances raise security concerns
- Social posts flagged the disappearance of JPL materials scientist Monica Jacinto Reza near Angeles National Forest. - The thread links her case to 11+ incidents involving propulsion or nuclear experts, suggesting a pattern. - Observers worry about targeted threats to technical personnel in the LA cluster, raising security and recruitment implications (x.com).
Monica Jacinto Reza, a 60-year-old aerospace engineer tied to NASA’s Jet Propulsion Laboratory, has been missing since a June 22, 2025 hike near Mount Waterman in the Angeles National Forest. (nbclosangeles.com) The Los Angeles County Sheriff’s Department said Reza was last seen around 9 a.m. near 60001 Trailheave Avenue in the Mount Waterman area, wearing a red long-sleeve shirt, green hiking pants and hiking shoes. Search crews from Los Angeles County and other Southern California teams expanded the operation through at least June 27, 2025. (nbclosangeles.com) (ktla.com) On June 29, 2025, the sheriff’s department said the initial response phase had ended, but the investigation would continue through its Homicide Bureau’s Missing Persons Unit. The department also said Reza had no known health conditions that would explain her disappearance. (ktla.com) Reza’s case moved back into national attention in April 2026, when CBS News reported that federal officials were reviewing deaths and disappearances involving workers tied to sensitive nuclear and space technology. CBS said people close to the various investigations had not found evidence of a single coordinated plot. (cbsnews.com) FOX 11 Los Angeles reported April 18 that the White House, the Federal Bureau of Investigation and the Department of Energy were conducting what it described as a “holistic review” of 11 scientists tied to aerospace and nuclear research who had died or vanished since 2024. The station said four of those cases were linked to Los Angeles County, including Reza and three other researchers with ties to Jet Propulsion Laboratory or Caltech. (foxla.com) That federal review is the clearest verified reason Reza’s disappearance is now being discussed as more than a local missing-person case. It does not establish that the cases are connected, and FOX 11 said officials had not confirmed any link among the 11 incidents. (foxla.com) Jet Propulsion Laboratory, based in Pasadena, is NASA’s center for robotic space missions and advanced science and engineering work. Its research programs include spacecraft technology and materials work, the field that studies how metals and other substances hold up under heat, stress and corrosion in flight hardware. (jpl.nasa.gov 1) (jpl.nasa.gov 2) (jpl.nasa.gov 3) FOX 11 identified Reza as an aerospace engineer and materials processor who worked for both Jet Propulsion Laboratory and Aerojet Rocketdyne, and said she was known for work on a specialized metal used in rocket manufacturing. That description has circulated widely in recent coverage, but the public record on her exact projects remains limited. (foxla.com) The verified facts in Reza’s case remain narrow: she went missing on a hike, a large search found no trace of her, and the sheriff’s investigation stayed open into 2026. The broader claims online now sit alongside a federal review that, so far, has raised questions without publicly answering them. (ktla.com) (cbsnews.com)
