The final moments of a wildlife enthusiast and his girlfriend were captured in a disturbing audio recording after the couple were attacked by a grizzly bear in the Alaskan wilderness.

Timothy Treadwell, 46, and Amie Huguenard, 37, died in October 2003 while camping in Katmai National Park and Preserve, where Treadwell had spent years documenting and protecting wild bears.

What makes their deaths particularly haunting is that a video camera recorded the sounds of their final struggle, preserving the desperate exchanges between the couple as the attack unfolded.

The recording was later heard by filmmaker Werner Herzog, who was so disturbed by its contents that he refused to include the audio in his documentary about Treadwell's life.

Who was Timothy Treadwell?

Treadwell was an American wildlife enthusiast who became known for spending 13 summers living among grizzly bears in Alaska.

He developed an extraordinary attachment to the animals, giving individual bears names and documenting their behaviour through photographs and video recordings.

His experiences eventually inspired the documentary Grizzly Man, directed by Werner Herzog and released in 2005.

However, Treadwell's approach to wildlife conservation was controversial.

National park officials repeatedly raised concerns about his proximity to dangerous animals, warning that his interactions could place both himself and the bears at risk.

Despite those concerns, he continued returning to the remote wilderness each summer.

What happened to Timothy Treadwell and his girlfriend?

In October 2003, Treadwell and Huguenard were staying at a campsite near Kaflia Bay in Katmai National Park.

The couple had remained in the area late into the season, when bears were preparing for winter and food could become increasingly difficult to find.

On October 5, they were attacked by a grizzly bear near their campsite.

When air taxi pilot Willy Fulton arrived the following day to collect them, he discovered a horrifying scene and alerted authorities.

Investigators subsequently recovered the couple's remains and discovered a video camera containing an audio recording of the attack.

Although the camera had been operating, its lens cap was on, meaning no images of the fatal encounter were captured.

What were Timothy Treadwell's final words?

According to accounts provided by Alaska State Troopers, Treadwell could be heard desperately calling for help as the bear attacked him.

Among the words investigators reported hearing were: "Come out here; I'm being killed out here."

Huguenard, who initially appeared to be inside their tent, responded by urging him to play dead.

When that failed to stop the attack, she reportedly encouraged him to fight back.

Investigators said Treadwell then asked Huguenard to get a pan and strike the bear.

Other accounts of the recording describe Huguenard repeatedly shouting for the animal to get away.

The recording eventually ended, leaving investigators to reconstruct the couple's final moments from the audio and evidence discovered at the campsite.

Although these are among the last reported words heard on the recording, the precise final words of both victims have not been publicly established.

Why was the recording never released?

The recording later became an important part of Herzog's documentary Grizzly Man, although audiences were never allowed to hear the attack itself.

In one of the film's most emotional scenes, Herzog listens to the audio through headphones while sitting beside Jewel Palovak, a close associate of Treadwell.

After hearing the recording, Herzog advised her not to listen to it herself and suggested that it should be destroyed.

He later explained that broadcasting the sounds of the couple's deaths would violate their dignity and privacy.

Rather than destroying the tape, Palovak reportedly placed it in a secure bank vault.

While recordings purporting to capture the attack have circulated online, the authentic audio has not been publicly released.

What did investigators discover about the attack?

Investigators concluded that Treadwell and Huguenard had been camping in an area frequently used by bears.

A subsequent National Park Service investigation determined that the attack occurred during daylight hours on October 5, rather than at night as initially believed.

Authorities also found that the campsite's location and the couple's history of close encounters with bears had created significant risks.

The tragedy highlighted the dangers of approaching large wild predators, even for people who have spent years observing their behaviour.

What happened after their deaths?

Herzog's documentary Grizzly Man was released in 2005, combining Treadwell's original footage with interviews and reflections on his unusual relationship with the wilderness.

The film received widespread critical acclaim and introduced Treadwell's story to a much larger audience.

More than two decades later, the couple's deaths remain one of the most widely discussed fatal bear attacks in modern American history.

And although the audio recording has never been released publicly, the accounts of those who heard it continue to offer a heartbreaking insight into their final moments.
