Bigfoot Investigator Marks 5 Years Since Mysterious Tent Blood Discovery

Five years. That's how long one researcher has been sitting on what could be the most compelling piece of physical evidence related to Bigfoot, and almost nobody in the community seems to care. That's the takeaway from a recent video that dives deep into one of the strangest incidents to ever come out of the Cascade Mountains. Back in June 2021, Matthew Hines of Encounters USA was deep in the northern Cascades with Russian researcher Igor Bersev. The two were standing right next to their tent, eating breakfast and talking about the day's plans, when something impossible happened. A pool of blood appeared on the floor inside the tent. Not a little smear. Enough to stop everything. And here's the part that makes this case so haunting: they were right there. There was no window of time for someone to sneak in, leave blood, and get out without being seen or heard. Hines, a U.S. Army veteran of the 82nd Airborne Division, isn't some wide-eyed newcomer to the field. He's spent years investigating Bigfoot, aliens, and Dogman reports. He's seen strange things before. But this one stuck with him. He checked himself for injuries, even considered whether he'd scratched a mosquito bite hard enough to bleed that much. Nothing added up. An animal couldn't have gotten inside. They weren't gone. The blood just... appeared. What followed was a five-year investigation that spanned multiple documentaries. Hines did everything by the book first. He documented the scene, preserved the samples, and reached out to labs, including the University of California, Davis Veterinary Lab. Most either weren't interested or wouldn't properly examine the blood. So he turned to unconventional methods, and that's where things got really interesting. Multiple independent remote viewers, some of the best in the field, came back with the same information. A professional psychic saw the same thing. Different people, different methods, same conclusion: multiple Bigfoot were present, and so were aliens. The blood, according to these viewers, was left intentionally. It wasn't random. It was a message, or a marker, or something that these intelligences wanted known. Hines didn't stop there. He went back to the same location, set up camp in the same spot, and tried to recreate the conditions to see if it would happen again. The activity in the area never really stopped, but the blood incident itself never repeated. He used military discipline, documentation, remote viewing, psychics, FLIR, night vision, trail cameras, everything he could think of. He produced an entire documentary series about it: Cascade Bigfoot Blood Mystery, parts one through four, plus a follow-up called Remote Viewed. And yet, despite all of this, almost nobody in the Bigfoot world has asked him to speak about it. No conferences. No Bigfoot shows. The only exception was Todd Nice, who invited him to speak at Beachfoot 2025, though Hines notes that was largely because other speakers didn't show up. Nice is also the associate producer on the Cascade Bigfoot Blood Mystery documentaries and has been one of the few people genuinely interested in the case. This is where the frustration really comes through in the video. Hines still has the blood samples. They're sitting in storage, waiting for someone willing to test them properly. And he makes a pointed observation: if this had happened to almost anyone else in the field, it would be talked about constantly. But for whatever reason, this case has stayed quiet. He suggests that maybe the community isn't as interested in finding real answers as it is in selling t-shirts and sweatshirts. That's a heavy accusation, but it's hard to ignore when you consider the facts. For anyone unfamiliar with the Cascades, this region has long been considered one of the most active areas for Bigfoot sightings in North America. The dense, old-growth forests, the rugged terrain, and the remoteness make it ideal habitat for a large, reclusive primate, if such a creature exists. Reports from the area go back decades, with witnesses describing everything from wood knocks to vocalizations to physical encounters. The northern Cascades, in particular, have been a hotspot for researchers, including the late René Dahinden, who spent years tracking reports in British Columbia and Washington State. What makes the Cascade blood mystery stand out is the physical evidence. Hair samples, footprint casts, and audio recordings are one thing. Actual blood, in a controlled situation, with two witnesses present and no logical explanation, is something else entirely. If properly tested, it could confirm or rule out a number of theories. The fact that it hasn't been tested, despite being in someone's possession for five years, is itself a mystery. Hines ends the video with a reminder to always watch your back when you're out there looking for the unknown. It's a sentiment that anyone who's spent time in the woods at night can appreciate. This is one of those cases that deserves more attention than it's gotten. The full video is worth watching for anyone interested in the unexplained. It's a firsthand account from a credible witness, backed by documentation, remote viewing sessions, and physical evidence that remains untested. Five years in, and the mystery is still wide open.
