Part 3: William McCasland and the Mystery of the 11 Missing or Dead Scientists
In this episode of the NVus Alien Podcast, Heather Woodward concludes her three-part investigation into the deaths or disappearances of eleven scientists and researchers that have raised questions, speculation, and some very strange recurring patterns. Part Three moves heavily into the world of national laboratories, nuclear weapons programs, defense technology, and classified research.
In this episode of the NVus Alien Podcast, Heather Woodward concludes her three-part investigation into eleven scientists and researchers whose deaths or disappearances have generated questions, speculation, and some very strange recurring patterns.
Part Three moves heavily into the world of national laboratories, nuclear weapons programs, defense technology, and classified research. Heather examines the disappearance of Melissa Casias, a Los Alamos National Laboratory administrative assistant whose skeletal remains were discovered nearly a year after she vanished. Casias left her home without her wallet, keys, or phones, and both phones had been factory reset. Her remains were eventually found in Carson National Forest near a handgun, although questions remained about how she died and whether the gun belonged to her.
The investigation leads directly into Los Alamos National Laboratory and its history beginning with the Manhattan Project. Heather looks at the laboratory's continued work involving nuclear weapons, fusion, particle accelerators, nanotechnology, supercomputing, national security, and other advanced technologies. She also explores Los Alamos' radioactive waste facilities and documented accidents involving plutonium and other radioactive materials.
Next is retired Los Alamos research and development engineer Anthony Chavez, who seemingly walked away from his home in May 2025. His car remained in the driveway. His wallet, keys, and phone were left behind. Searches of nearby trails and Pueblo Canyon failed to locate him, and his family described the disappearance as completely out of character.
Heather then examines the disappearance of Steven Garcia, a government contractor connected to the Kansas City National Security Campus. Garcia was captured on surveillance leaving his Albuquerque home on foot with a handgun, while leaving behind his phones, keys, and wallet. His workplace produces the majority of the non-nuclear components used in America's nuclear weapons stockpile, including high-energy lasers, ignition systems, microwave hybrids, microcircuits, and other advanced technologies.
Finally, Heather investigates perhaps the strangest and most high-profile disappearance in the series: Major General William McCasland.
McCasland commanded the Air Force Research Laboratory at Wright-Patterson Air Force Base and managed a multibillion-dollar science and technology program involving thousands of personnel. His career crossed astronautical engineering, missile systems, space acquisition, classified programs, Kirtland Air Force Base, and the Pentagon. In February 2026, McCasland disappeared from his New Mexico home, leaving behind his phone, glasses, and wearable devices. Despite extensive searches involving helicopters, drones, dogs, and infrared equipment, he remained missing at the time of the episode.
McCasland also introduces the one explicit UFO connection in the eleven cases. His history with Wright-Patterson intersects with decades of stories surrounding alleged recovered craft and reverse-engineering programs, while David Grusch later publicly connected McCasland to alleged craft-recovery and reverse-engineering programs.
After examining all eleven cases, Heather steps back and asks the larger question: Is there actually a pattern?
Her working hypothesis isn't primarily about extraterrestrials. Instead, she explores whether the overlapping research into nuclear technology, advanced materials, aerospace, missiles, energy, communications, space infrastructure, artificial intelligence, and emerging defense systems could represent pieces of a much larger classified technological program.
A kind of Manhattan Project 2.0.
The original Manhattan Project compartmentalized enormous scientific efforts toward a goal that many participants couldn't fully see. Heather considers whether something similar could be happening now, except this time the frontier isn't simply nuclear weapons. It may involve energy, space-based defense, advanced communication systems, artificial intelligence, new materials, and technologies capable of fundamentally changing existing industries and geopolitical power.
Individually, the eleven cases may have completely unrelated explanations. Together, however, Heather argues that their professional worlds repeatedly overlap in ways worth examining.
