IF YOU SEE HIM, YOU’RE ASKED TO CALL 911 RIGHT AWAY. WELL, IT IS A MYSTERY DRAWING NATIONAL ATTENTION. TEN SCIENTISTS INVOLVED IN NUCLEAR AND AEROSPACE DEFENSE TECHNOLOGY HAVE DISAPPEARED OR DIED IN RECENT YEARS. OF THOSE TEN, FOUR ARE FROM NEW MEXICO, INCLUDING A MISSING FORMER KIRTLAND AIR FORCE BASE COMMANDER. NOW, A NEW PUSH FROM LAWMAKERS IS URGING THE TRUMP ADMINISTRATION TO DIG DEEPER FOR ANSWERS. REPORTER JOHN RUPOLO JOINS US IN STUDIO TO EXPLAIN. JOHN. SASHA, IS IT A COINCIDENCE OR IS THIS SOMETHING DEEPER? WHAT HAPPENED TO THE SCIENTISTS WHO ALL HAD CONNECTIONS TO U.S. NUCLEAR SECRETS? NUCLEAR RESEARCH, RESEARCH, OR AEROSPACE? MANY, NOW, INCLUDING LAWMAKERS, ARE CALLING THEIR DEATHS OR DISAPPEARANCES SUSPICIOUS. FOUR OF THOSE SCIENTISTS WHO HAVE DIED OR DISAPPEARED IN THE LAST FEW YEARS ARE FROM NEW MEXICO. ALL TEN OF THEM HAD CONNECTIONS TO U.S. NUCLEAR SECRETS OR ROCKET TECHNOLOGY. THE MOST RECENT DISAPPEARANCE HERE IN ALBUQUERQUE. RETIRED AIR FORCE MAJOR WILLIAM MCCASLAND LAST SEEN FEBRUARY THE 27TH. HE WENT HIKING IN THE SANDIAS AND HASN’T BEEN SEEN SINCE. TWO OTHERS FROM NEW MEXICO WERE EMPLOYEES OF LOS ALAMOS NATIONAL LABORATORY. ANTHONY CHAVEZ MISSING SINCE MAY 2025. AND MELISSA CASIAS MISSING SINCE JUNE OF 2025. SHE WAS LAST SEEN WALKING ALONG STATE ROAD 518 IN TALPA, NEAR TAOS. FEDERAL OFFICIALS HAVE NOT IDENTIFIED A CONNECTION BETWEEN THE MISSING SCIENTISTS, BUT WHAT THEY DO HAVE IN COMMON IS ACCESS TO U.S. SCIENTIFIC INFORMATION. THIS WEEK, THE HOUSE COMMITTEE ON OVERSIGHT AND GOVERNMENT REFORM SENT THIS LETTER TO FEDERAL AGENCIES, INCLUDING DEPARTMENT OF WAR SECRETARY PETE HEGSETH AND FBI DIRECTOR KASH PATEL. THEY WROTE, WE REQUEST A BRIEFING ON ANY INFORMATION REGARDING THESE DEATHS AND DISAPPEARANCES. LAWMAKERS WENT ON WRITING THE DEATHS AND DISAPPEARANCES MAY REPRESENT A GRAVE THREAT TO U.S. NATIONAL SECURITY. ONE LAWMAKER ON THE COMMITTEE, REPRESENTATIVE ERIC BURLISON OF MISSOURI, SAID HE WOULDN’T BE SURPRISED IF CHINA, RUSSIA OR IRAN IS BEHIND TAKING OUT SOME OF THE NATION’S TOP SCIENTISTS. THE LETTERS ALSO MENTIONED MCCASLIN’S DISAPPEARANCE, AND BOTH CHAVEZ AND CASILLAS. PRESIDENT TRUMP SPOKE ABOUT THE MISSING SCIENTISTS LAST WEEK. WELL, I HOPE IT’S RANDOM, BUT WE’RE GOING TO KNOW IN THE NEXT WEEK AND A HALF. I JUST LEFT THE MEETING ON THAT SUBJECT, SO PRETTY SERIOUS STUFF. WE ALSO SPOKE TO NEW MEXICO CONGRESSWOMAN MELANIE STANSBURY ABOUT THE INVESTIGATION. MY UNDERSTANDING IS THAT THIS IS BEING HANDLED AT THE HIGHEST LEVELS OF SECURITY. SO AT THIS TIME, WE DON’T HAVE INFORMATION THAT WE CAN SHARE DIRECTLY ABOUT ANY POTENTIAL CONNECTIONS BETWEEN THESE INDIVIDUALS. ALL RIGHT. LOTS TO TALK ABOUT. WE REACHED OUT TO LOS ALAMOS NATIONAL LAB ABOUT THIS INVESTIGATION, BUT WE NEVER HEARD BACK. TO BE CONTINUED IN THE STUDIO, JOHN RUPOLO, KOAT ACTION SEVEN NEWS. JOHN. THANK YOU. THE FOURTH NEW MEXICAN MISSING, STEVEN GARCIA WAS THE PROPERTY CUSTODIAN FOR KANSAS C
Fact-checking claims about missing, dead scientists: Were they researching UFOs, nuclear weapons?
Updated: 3:10 PM PDT Apr 29, 2026
Social media users are posting about people who died or disappeared, claiming they are all scientists who knew secrets about nuclear research and unidentified flying objects.They theorize that what happened to these people, who have died or disappeared since 2021, is concerted and not a coincidence. A viral April 14 X post read, “Can anyone explain what the deal is with all the missing scientists lately? We’ve had like 10 disappearances in the last two years. …What’s the deal? It’s too much to be coincidence. It’s a legitimate anomaly. It’s spooky.”A former lawmaker is also posting about it.”There are 11 missing or dead or suicided scientists all linked to space or military programs and the FBI just now opened a ‘probe,’” former congresswoman Marjorie Taylor Greene posted April 22 on X.Discussion about the scientists isn’t limited to social media. The FBI and the House Oversight Committee said they are investigating any potential connections among the missing and dead scientists and whether a national security threat exists. NASA, where several of the people were employed, said it is working with the relevant agencies. This story was originally published on PolitiFact. Read it here.President Donald Trump told reporters April 16 that he had a meeting on the topic and “we’re gonna look at it over the next short period.” We tracked 14 names that have surfaced in these posts. We examined their backgrounds and the circumstances of their deaths or disappearances, and some of the claims about potential connections among them don’t hold up. We also found that they were not all scientists. Here’s what’s been said and what we know. The people did not all work togetherSome social media posts claimed the people were professionally affiliated. An April 8 X post said, “Nearly all of them worked together — and died or vanished within the last two years.”That’s overstated. We found no evidence that “nearly all” were colleagues.
