Missing hiker (Monica Reza)

[Matthew]

So, what's the theory here? That she was snatched by a foreign power for her secret knowledge?

Sean you have the ability to bring sasquatch into this Convo and it might actually be credible lol

I'm not accusing Squatchy of anything, but it's a fact that he can leap from tree to tree while carrying a small woman. Has anyone pursued this possibility?

super long write up about the monica reza situation that references Eispiraten quite a bit.

That reads exactly like some AI-narrated YouTube videos I've watched. I mean the grammar, cadence, etc.

I'm not familiar with the trail she was on, I haven't really looked into this, etc etc. However, my Jonathan Creek-y possibilities include she was never there, her fellow hikers were involved in her disappearing (either against her will or to help her out), she was snatched by a foreign power (there are a lot of espionage agents around), she was taken care of by Sinister Government Forces, or she just disappeared on her own to start a new life, because she feared something, to take part in a special govt project, to join some sort of witness protection program, etc.

Hey everyone, we were invited to post here, so we wanted to introduce ourselves and, more importantly, say thank you.

We're The Sentinel Network on Substack. Some of you may have come across our ATTRITION series, which covers the Reza case alongside several other disappearances in the defense aerospace space. We publish anonymously and have been covering this space since late 2025.

We want to be upfront about something: we haven't come to any hard conclusions about what happened to Monica. We try to follow the evidence, document the anomalies, and try not to speculate.

We want to be upfront about something: the work this community has done was instrumental in getting this story to national news. The searches. The maps. The timelines. The documentation of search route management. The firsthand site visits. That is real investigative work. Granular, on-the-ground efforts can't be replicated from behind a screen. When we were building out the evidentiary chain for our articles, the detailed record you all built here was a critical resource.

The fact that CNN, NewsNation, Newsweek, and others eventually picked up this thread is not an accident. It happened because people here cared enough to document what they were seeing with discipline and specificity.

Thank you for the invite to post. And thank you for what you've done for Monica's case.

Congressman Calls for FBI Help Over Missing General, Scientists
Published Mar 31, 2026 at 12:26 PM EDT

Representative Eric Burlison, a Missouri Republican, said he has requested the involvement of the FBI in the “deeply concerning” disappearances of a retired general and a scientist with links to advanced research.

The Context
William Neil McCasland, a retired Air Force major general, was last seen on February 27 at about 11 a.m. in the area of Quail Run Court NE, in Albuquerque, New Mexico, according to the Bernalillo County Sheriff's Department.

McCasland held senior leadership roles in the U.S. Air Force spanning science, technology and space research. His disappearance renewed attention on the unsolved case of aerospace engineer Monica Reza, who disappeared months before while hiking. Reza previously worked on a government‑funded rocket materials project overseen by McCasland.

Any concrete connection between the cases remains unclear. The Sheriff's Department previously told Newsweek that detectives were “looking into this to see if there is any connection at all." “It’s remarkable that General McCasland apparently walked out of his home, left all of his devices and never came back,” Burlison told Fox News. “And Monica Reza, she was on a hike as well and mysteriously disappeared. And I’ve heard of others…

“I sent a letter to the FBI investigating the suspicious suicide of another individual who had worked alongside other whistleblowers like David Grusch and Jake Barber, who had come forward. So their colleague mysteriously committed suicide. We’ve already sent the letter to the FBI to investigate that and that is an ongoing investigation. “So these are other things that we’ll probably be reaching out to the FBI to see if they have anything going on on these and if not, then we’re going to ask them to do that.”

Newsweek contacted the FBI for comment via email on Tuesday. Burlison previously said that McCasland has “a lot of information” about unidentified flying objects (UFOs)—a connection that has led to speculation about the nature of the retired general’s disappearance. McCasland’s wife, however, has pushed back against the notion.

What People Are Saying
Representative Eric Burlison, a Missouri Republican, on X on Monday: “The disappearance of multiple scientists and military personnel with ties to advanced research is deeply concerning. I’ve already requested FBI involvement, and we will keep pressing for answers.”

What Happens Next
Jennifer Coffindaffer, a former FBI agent, told Newsweek this month that it could take some time before authorities locate McCasland, whom she believes died by suicide. “It's a needle in a haystack finding an individual in the Sandia Mountain foothills,” she said. “It's impossible for a learned and astute outdoorsman to be found quickly because it’s so difficult, the terrain, and you can't do a grid search.”
