The Bernalillo County Sheriff’s Office (BCSO) in New Mexico has addressed theories surrounding the high-profile disappearance of retired Air Force general William Neil McCasland in February, telling Newsweek it is aware of the speculation surrounding the case but remain focused on verified facts and credible leads.
McCasland’s disappearance has drawn attention within UFO circles, where some have speculated that it could be linked to his work, despite no confirmation of any foul play from police. McCasland’s wife, however, has previously pushed back on claims that his work had any link to his disappearance.
The Context
According to the BCSO, the 68‑year‑old’s last known location was at or near his home in the Quail Run Court NE area on the morning of Friday, February 27, 2026, in Albuquerque, New Mexico.

His phone, prescription glasses and wearable devices were found at the home, while his hiking boots, wallet and a .38‑caliber revolver were reported missing. Police also noted that he had an unspecified medical condition.
As previously reported by Newsweek, McCasland held high-ranking roles in the U.S. Air Force spanning science, technology and space research, and was a commander of the Air Force Research Laboratory at Wright‑Patterson Air Force Base. His career included key roles in space acquisition and operations, as well as Pentagon posts on defense, space and technology initiatives.
The case has also attracted congressional attention, with Missouri Republican Representative Eric Burlison suggesting previously McCasland has "a lot of information" on the topic of UFOs.

What To Know
“We are aware of the speculation surrounding this case. As with any high-profile investigation, that kind of attention can create additional tips and information that investigators must review, but our team remains focused on the facts and on pursuing credible leads,” BCSO said in an email to Newsweek.
“At this time, we have not developed evidence establishing that Mr. McCasland’s disappearance is connected to his classified work. This remains an active investigation, and we are not going to speculate or rule in or rule out possibilities without evidence.”
Reporting has also tied McCasland’s case with the deaths or disappearances of several U.S. experts in the advanced space, defense, and nuclear fields in recent years.
However, the BCSO told Newsweek it had no verified information establishing any connection between the retired general’s disappearance and any other missing person investigation.
What Happens Next
The investigation continues. The BCSO previously told Newsweek McCasland’s case remained a top priority for its office.
