In Albuquerque, New Mexico, retired Maj. Gen. William N. "Neil" McCasland was last seen at his home on February 27, 2026. At around 10 a.m. that day, he was seen interacting with a repairman at his residence. Shortly after, his wife left for a medical appointment, returning around noon to find him missing. The Bernalillo County Sheriff's Office has reported that McCasland showed signs of mental fog but was considered highly intelligent and capable. When McCasland's disappearance was reported at 3:07 p.m., authorities began an extensive search. As the investigation progressed into the third week without solid leads, authorities found hiking boots believed to belong to him at his vacation home. A gray U.S. Air Force sweatshirt was also discovered about 1.25 miles away from his residence, but there has been no confirmation regarding its association with him. Notably, McCasland left behind his phone, wallet, and a .38 caliber revolver, raising suspicion and concern. Authorities have indicated there is no evidence of foul play surrounding the disappearance. Investigators have used drones, helicopters, and canines in their search efforts while canvassing hundreds of homes for surveillance footage. Despite these efforts, no confirmed sightings of McCasland have emerged, nor has any criminal activity been substantiated in connection with his case. McCasland, an experienced aerospace engineer, has had numerous roles within the Air Force and has led various research programs. His wife, Susan McCasland Wilkerson, has addressed public speculation linking his military background to his disappearance, emphasizing that he had retired nearly 13 years earlier and held only basic security clearances. As the investigation continues, authorities are urging the public to assist by checking surveillance footage from the time surrounding his disappearance and reporting any tips.
