A former military scientist vanished from his home in a narrow window of time, leaving behind his phone, glasses, smartwatch and even the clothes he had worn that morning. Despite extensive searches using helicopters, drones, dogs and neighborhood surveillance, there was no sign of him leaving the area and no trace of where he went. Investigators uncovered missing items, including a revolver. His past work in classified aerospace programs, a brief connection to UFO researchers and a recent cluster of disappearances and deaths among other scientists fueled widespread speculation.
