Tennessee Republican Rep. Tim Burchett raised alarms about a possible conspiracy involving scientists and researchers tied to UFO research, stating that recent deaths and disappearances are not coincidental.

Burchett, a vocal advocate for UFO disclosure, told NewsNation that 11 individuals close to the issue have either died or vanished. "We’ve had testimony. You’re seeing 11 people have either died or disappeared that have been close to this issue, whether that’s a coincidence or not," he said during an appearance on Elizabeth Vargas Reports. He added, "Something dark is going on. I know these scientists and researchers. They have testified. We’ve got to get to the bottom of it."

The congressman has pointed to cases like retired U.S. Air Force Maj. Gen. William Neil McCasland, who disappeared from his Albuquerque, New Mexico, home on February 27, 2026, during what appeared to be a short walk. McCasland, 68, formerly commanded the Air Force Research Laboratory at Kirtland Air Force Base and had brief ties to To The Stars Academy, a group founded by musician Tom DeLonge to study UFOs. His wife, Susan McCasland Wilkerson, has rebutted UFO connections, noting he retired 13 years ago with only routine clearances since.

Other cases include NASA materials engineer Monica Jacinto Reza, 60, who vanished while hiking in Angeles National Forest on June 22, 2025; astrophysicist Carl Grillmair, shot dead on his porch on February 16, 2026; and MIT plasma physicist Nuno Loureiro, murdered in December 2025. Earlier incidents involve anti-gravity researcher Amy Eskridge, who died by suicide in June 2022, and UFO author David Wilcock, who fatally shot himself on April 20, 2026, outside his Colorado home. Burchett responded to Wilcock's death on social media with "Not cool" and later said to the Daily Mail, "I just don’t think there’s any chance that this is just all coincidental."

The theory has spread online, linking the cases to UFO cover-ups or foreign adversaries targeting U.S. experts in aerospace and nuclear fields. Burchett told WIBC the numbers in these research areas "seem very high," adding, "I think we’d better be paying attention, and I don’t think we should trust our government." He suggested whistleblowers fear for their lives, saying some are "afraid someone will disappear them."

In response, the House Oversight Committee launched a probe last week, seeking briefings from the Defense Department, Energy Department, FBI, and NASA on potential national security threats. The FBI announced it would examine connections among the cases, coordinating with other agencies. NASA stated it sees no security threat and is cooperating.

President Donald Trump addressed the matter last week, telling reporters, "I hope it’s random, but we’re going to know in the next week and a half. Pretty serious stuff." Families and experts have dismissed patterns, calling the links coincidental amid thousands in similar fields.

Burchett, who has viewed classified UFO footage he says "defies logic," continues pushing for transparency amid ongoing congressional UFO hearings.
