Online sleuths think they have uncovered missing retired Air Force general William Neil McCasland’s anonymous social media account — which claimed another general was murdered for his dealings with nuclear material.
McCasland, 68, went missing from his Albuquerque, NM, home on Feb. 27 — which is the same day that the person behind a conspicuously credentialed X account centered on spacecraft and advanced science made their last post.
The account @tmbspaceships claims to be run by a “retired 38-year active duty” United States Air Force with a PhD in engineering — listing the Air Force Institute of Technology (AFIT), the Air Education Training Command (AETC), and Air Force Material Command (AETC) as places they’ve worked.
Both the AFIT and AFMC are located at Wright-Patterson Air Force Base, which McCasland ran from 2011 to 2013. He attended the Air War College during his 34-year career, which is a subordinate to the AETC. McCasland attained a PhD in Astronautical Engineering from MIT in 1988.
The account shockingly claimed just months before McCasland’s disappearance that Maj. Gen. John Rossi, who allegedly committed suicide in 2016, was actually murdered because of refusal to hand over nuclear material to private contractors.
The 55-year-old two star general ended his life just two days before receiving a third star and taking the reins at US Army Space and Missile Defense Command, Army Times reported.
Army investigators ruled his hanging death was due a severe lack of sleep and job anxiety, according to the outlet.
“Gen. Rossi was a good friend and it is my opinion he did not commit suicide,” the account wrote in a reply posted on Sept. 2, 2025.
“I believe Gen Rossi was killed because of a [sic] incident, reported to the pentagon IG [inspector general], that he would not transfer nuclear weapons to private hands, just months prior in an attempted Nuclear Weapons theft from Ft. Sill,” the post claimed.
“Gen. Rossi knew DOE takes all custody of nuclear weapons, not private contractors,” the post concluded.
McCasland was informed about some of the most secretive US technology in his capacity as leader of Wright Patterson Air Force Base, vice commander of the Space and Missile Systems Center, and director of Space Acquisition at the Pentagon, sources told The Post.
“During his time he was one of the key gatekeepers for the UFO topic for the Air Force,” a source with knowledge told The Post. “He knew a lot, and he participated.”
Wikileaks disclosures of the emails of John Podesta, former counselor to President Obama revealed that Blink-182 frontman Tom DeLonge was in contact with McCasland who briefed him on the subject of UFOs and alien life.

McCasland was integral behind the scenes in setting up the “I Miss You” crooner’s “To The Stars Academy” — which boasted an advisory board that included former director at Lockheed Martin’s Skink Works Steve Justice, UFO researcher and physicist Hal Puthoff, and former Pentagon Unidentified Anomalous Phenomenon investigator Luis Elizondo.
The search for the general has entered its second week, with investigators providing an updated timeline on the day he went missing.
McCasland was last seen by his wife Susan at 11:10 a.m. local time. She returned from a medical appointment at 12:04 p.m. to find an empty home and no trace of her husband, according to the Bernalillo County Sheriff’s Office.
Investigators said his hiking books, wallet, and .38 caliber revolver with leather holster were missing from the home.
Susan McCasland is also a retired government physicist, a second lieutenant with the Air Force and former military contractor employee, according to an online bio.
In a Facebook post one week after his disappearance, Susan bizarrely suggested McCasland could have been abducted by a UFO “mothership.”
“Though at this point with absolutely no sign of him, maybe the best hypothesis is that aliens beamed him up to the mothership,” she said in a Facebook post on March 6.
“However, no sightings of a mothership hovering above the Sandia Mountains have been reported,” she concluded.
She did not respond to requests for comment.
