William “Neil” McCasland, a retired U.S. Air Force general aged 68, has been missing for nearly two weeks, leaving his family and community in distress.

In a heartfelt Facebook post shared on Friday, his wife, Susan McCasland Wilkerson, expressed the urgency and complexity of the search efforts. “There has been no indication whatsoever of where he might be,” she stated. The search has been extensive, involving dozens of volunteers and official personnel on foot. Friends and neighbors have joined the efforts, coordinating closely with authorities. The search has also included horseback patrols, drones equipped with advanced capabilities, helicopters, various types of search dogs, and thorough neighborhood canvassing. They have even been reviewing footage from Ring cameras and wildlife videos in hopes of finding clues.

Efforts to contact Susan McCasland Wilkerson for further comments were not immediately successful, as reported by Fox News Digital.

While a silver alert has been issued for McCasland, his wife insists that his disappearance is not linked to any signs of confusion or disorientation. She emphasized that although “Neil is at some risk,” it is not due to dementia or similar conditions.

A photo of McCasland, undated, shows him dressed in hiking gear, capturing the image of a man who enjoyed the outdoors. He was last seen in the vicinity of his home in Albuquerque, New Mexico, on February 27.

“Neil is at some risk, but not from dementia,” she wrote.

She also downplayed his military record as a reason for his disappearance.

“It is true that when Neil was in the Air Force, he had access to some highly classified programs and information,” she wrote. “He retired from the AF almost 13 years ago and has had only very commonly held clearances since. It seems quite unlikely that he was taken to extract very dated secrets from him.”

Before his retirement in 2013, McCasland was the commander of the Air Force Research Laboratory at Wright-Patterson Air Force Base in Ohio. The base served as the headquarters for a military program monitoring unidentified flying objects from 1947 to 1969, according to the government.

She also noted that he had previously maintained a relationship with Blink-182 frontman Tom DeLonge as an unpaid consultant on military and scientific matters related to UFOs for the rocker’s fiction and media projects.

“This connection is not a reason for someone to abduct Neil,” she wrote.

He has no “special knowledge” about extraterrestrials or Roswell, New Mexico, according to his wife, who appeared frustrated with the search effort’s lack of progress.

“Though at this point with absolutely no sign of him, maybe the best hypothesis is that aliens beamed him up to the mothership,” she added. “However, no sightings of a mothership hovering above the Sandia Mountains have been reported.”

McCasland was last seen at his residence on Quail Run Court in Albuquerque on Feb. 27, according to the Bernalillo County Sheriff’s Office.

He is described as 5 feet, 11 inches tall with white hair and blue eyes and is believed to have left his residence on foot. He is an avid outdoorsman and is known to often hike, run, and cycle in the Northeast Heights and the Sandia foothills.

Images from his Facebook profile show he was often spending time in the mountains — both skiing and hiking — in the U.S. and abroad.

The sheriff’s office, FBI and other assisting agencies did not immediately see any signs of foul play, according to a statement released on March 6.

“We are asking for your help in finding him,” the Bernalillo sheriff’s office said in a statement. “We believe there are people who have information valuable to locating Neil who have not yet spoken to law enforcement. This could include people who have been in the Sandia mountains and may have seen Neil or captured him on a GoPro or other recording device, specifically on Friday, February 27 or Saturday, February 28.”

The sheriff’s office is asking anyone with any information to come forward, even if they don’t think what they know is important.

“Regardless of how insignificant you think your information might be, or whether you think we are already aware of it, please contact us and allow us to make that determination,” the statement continued.

Anyone with information can text “BCSO” to 847411 or call the missing persons unit at 505-468-7070.

“We would also like to remind the public of some hiking safety tips: Pick the right trail for you and your group’s ability, remember to let people know where you are, dress in layers, be sure to have enough water and always take your cell phone or some other way to communicate,” authorities said.
