Grizzly Bear Killed 25-Year-Old Swiss Tourist in Yellowstone. Here’s What Went Wrong.

The tragic death of 25-year-old Swiss tourist Brigitta Fredenhagen in Yellowstone National Park continues to serve as a haunting reminder of how quickly the wilderness can turn fatal. Fredenhagen made what some experts, including journalist Johnny Dodd and YouTube outdoorsman Chuke, agree was a single, fatal mistake: she went camping alone in grizzly country. Now, as bears begin emerging from hibernation each spring, outdoor veterans are sounding the alarm again. What happened to Brigitta – and how can it be prevented from happening again?

As reported by Johnny Dodd in a piece for AOL, the story of Brigitta Fredenhagen’s death is detailed in the newly released book Incredible Bear Attacks by Lamar Underwood. Underwood, a seasoned outdoor writer and former editor-in-chief of Sports Afield and Outdoor Life, doesn’t mince words: spring is bear season. “Just wait,” he warns, “it won’t be long now.” Bears awaken from hibernation hungry and agitated, and human activity often intersects with their path during this time.

Chuke of Chuke’s Outdoor Adventures echoes this warning in a recent video. “They’re waking up, they’re hungry, and they’re angry,” he says, predicting a spike in bear attacks in areas like Yellowstone, Glacier National Park, and Alaska. While both sources emphasize that most bear encounters pass without incident, the few that go wrong are unforgettable – and sometimes fatal.

Fredenhagen was described by Underwood as an experienced hiker. In July 1984, she set out to explore Yellowstone’s backcountry alone. She prepared well – cooked her food, hoisted it into a tree away from camp, and settled into her tent for the night. But when she failed to check in the following day, rangers were sent to investigate.

What they found was gruesome. According to Underwood’s account in Dodd’s article, a grizzly bear had ripped through the tent, dragged Brigitta out, and scattered pieces of her body around the campsite. It was a horrifying scene and one of the most brutal attacks Underwood has ever documented. “They will absolutely rip you apart,” he said, describing the bear’s method of attack – an overwhelming combination of claws and teeth.

Both Johnny Dodd and Chuke emphasize the same critical detail: Brigitta went alone. “She only made one mistake,” Underwood says in Dodd’s article. Chuke, however, takes this further, saying in his video, “I think she made a couple more mistakes than just that.” His point? While traveling alone is risky enough, there are additional precautions that even experienced hikers sometimes overlook.

Going solo into bear country drastically reduces one’s odds of survival in an encounter. Bears are more likely to attack if surprised, and a single human offers little deterrent. Chuke admits he’s been guilty of solo hikes himself but plans to stop. “It’s the people that go alone that usually get eaten,” he says bluntly.

Fredenhagen did most things right. She properly stored her food—an essential practice in bear territory. But according to Chuke, that’s not always enough. He suggests going a step further: sealing food in multiple Ziploc bags to minimize scent, and hanging it far from camp, not just high in a tree. “Make sure it’s a ways away from your tent,” he stresses.

Despite all these precautions, the truth remains: in bear country, there are no guarantees. Bears can still be drawn by residual smells, or even by curiosity. In Brigitta’s case, even her best efforts couldn’t save her once she was alone and vulnerable.

Chuke also brings up a major debate among outdoorsmen – bear spray versus firearms. While bear spray is commonly recommended, Chuke has concerns. “Bear spray is great, but I think it’s a poor choice by itself,” he says. He recounts recent stories where hunters deployed bear spray only to have the wind blow it back in their faces. The result? The bear kept coming, and people got bitten.

Instead, Chuke advocates for carrying a firearm in addition to bear spray. “A 12-gauge shotgun with slugs is one of the best bear defenses you could ever have,” he says. For those not lugging a shotgun, he recommends high-powered handguns like the .454 Casull or even modified pistols chambered in .460 Rowland, which offer near-.44 Magnum power in a semi-auto format.

Underwood doesn’t just write about bear encounters – he’s had his own. In the 1980s, during a fishing trip in Alaska, he found himself alone on a riverbank after his guide and partner walked upstream. When he heard rustling in the alder bushes, instinct took over. He sprinted back toward the others, shotgun in hand. “I knew exactly what it was and it was so close I could smell the scent of moist, wet fur,” he recalls.

It’s that instinct – the acute sense of imminent danger – that saved him. But as he admits, “That could have been my own tragic bear story – but I guess it wasn’t my time.”

According to Underwood, 99 out of 100 grizzly encounters end without incident. “The one thing victims have in common is being in the wrong place at the wrong time,” he told Dodd. Making noise, traveling in groups, and avoiding dense brush are all key strategies. But when that one percent chance turns real, the outcome can be devastating.

Chuke agrees. “Just don’t be the unlucky one,” he warns. It’s not about being fearless – it’s about being smart, prepared, and realistic about the dangers.

The Power of the Predator

Grizzly bears are not just big – they’re apex predators. As Underwood describes in his book and the AOL article, they can weigh up to 800 pounds and stand over six feet tall. Their strength is almost beyond comprehension. When they attack, it’s not a contest; it’s a mauling.

This raw power is why even a momentary lapse in judgment, like hiking alone, can become fatal. The bear isn’t hunting humans. It’s reacting to a threat, startled, or seeking food. But once it commits, the outcome is often horrific.

Brigitta Fredenhagen’s death was avoidable, but not because she was careless. She was smart, prepared, and experienced. But she went alone, and in grizzly country, that’s too big a gamble. The lesson is simple, says Chuke: “Don’t go alone. And if you do, be armed.”

In many ways, this case highlights the razor-thin margin for error in wild places. Yellowstone is one of the most breathtaking places in the U.S., but it’s also home to some of the most powerful animals on Earth. Respecting that duality is the first step toward staying alive.

As the snow melts and hikers head back into the backcountry, both Johnny Dodd and Chuke urge caution. The bears are waking up. Their instincts are primal. And every year, a handful of people don’t make it home.

“We’re going to hear stories any day now,” Chuke warns. It’s a sobering thought, but an honest one. Nature doesn’t give warnings – it gives consequences.

The outdoors offers incredible beauty, but also serious risks. Fredenhagen’s story reminds us that experience doesn’t guarantee safety. Whether you’re in Yellowstone, Alaska, or the backwoods of Montana, never underestimate a bear – and never overestimate your own invincibility.

In the words of Lamar Underwood: “They are one of the most dangerous animals on the planet. The ultimate predator.” And in the end, it only takes one wrong step, one quiet night in a tent, for that truth to become fatal.
