Haunting 911 call reveals clue in search for missing Air Force general

Chilling new details have emerged surrounding the disappearance of a retired Air Force general tied to UFO secrets and a string of missing or dead US scientists.

A frightened 911 call has been released, capturing a police dispatcher speaking with the wife of William Neil McCasland, 68, who vanished without a trace on February 27.

Susan Wilkerson is heard telling authorities that she believed the former general ‘had planned not to be found’ after finding her husband’s phone and other personal items still inside their New Mexico home.

‘He’s left his phone. He changed his clothes into I don’t know what. I think he’s on foot. All of our cars and bicycles are in the garage,’ Wilkerson said approximately three hours after McCasland disappeared.

‘He turned it off and left it behind which seems kind of deliberate because he’s always got his phone. He has a smartwatch. I don’t know if that’s with him or not,’ Wilkerson continued in audio obtained by the Law&Crime Network.

After the 911 call, Wilkerson later claimed that ‘foul play’ was not suspected in the general’s disappearance, but noted that McCasland left home with only a pair of boots and his .38-caliber revolver.

The retired Air Force officer, reportedly tied to both nuclear and UFO-related government programs, did not take any of his wearable devices or his prescription glasses, leaving behind any way of tracing or contacting him.

While Wilkerson pushed back on the possibility that her husband may have intended to harm himself, she revealed to 911 that he had been seeing a doctor for both physical and mental irregularities before he disappeared.

This is a breaking story. More details to follow.

When asked by the dispatcher if McCasland had been diagnosed with any type of mental disorder before vanishing, the general’s wife disclosed that he had been dealing with anxiety and short-term memory loss recently.

Wilkerson also told 911 the 68-year-old military veteran had been struggling with a lack of sleep, and then revealed McCasland feared his brain was ‘deteriorating.’

The dispatcher can be heard asking Wilkerson if her husband kept any guns in the home and if any of them were missing.

She replied that McCasland has a gun safe, adding that ‘he has quite a number of pistols and rifles,’ not knowing at the time that one of the handguns had been taken.

Wilkerson then addressed the missing general’s recent comments to her about his health, saying that she did not believe he was seriously considering ending his life.

‘Other than saying if his brain body keeps deteriorating, he didn’t want to live like that. But it seemed to me that was just a “man, I hate how this is going” kind of thing,’ Wilkerson said in the 911 recording revealed on Law&Crime’s Sidebar with Jesse Weber.

The Bernalillo County Sheriff’s Office issued a Silver Alert for McCasland, typically used to find a missing senior citizen who potentially has Alzheimer’s disease, dementia or another mental disability.

However, there have been no breaks in the case since that time, and no trace of the missing general since he was last seen near Quail Run Court NE in Albuquerque around 11am local time.

McCasland’s disappearance was the most recent in a potentially sinister pattern dating back to 2024. 

The retired general had been in command of the Air Force Research Laboratory (AFRL) at Wright-Patterson Air Force Base in Ohio, a facility tied to UFO conspiracy theories for decades.

According to UFO researchers and former government scientists, Wright-Patterson is the base where debris from the alien spacecraft that allegedly crashed in Roswell, New Mexico was taken for analysis.

On Monday, Tennessee Congressman Tim Burchett told WABC radio in New York that McCasland was the key figure in America’s secret research into UFO and extraterrestrial technology.

Burchett said: ‘He’s the guy that had a lot of nuclear secret. I’ve been told by several sources that he was the gatekeeper for the UFO stuff.’ 

McCasland was also previously stationed at New Mexico’s Kirtland Air Force Base, which has close ties to the Los Alamos National Laboratory (LANL) – one of America’s most important nuclear research facilities.

In 2025, three other people connected to AFRL and LANL vanished without a trace in almost the exact same manner as McCasland.
