Wildlife workers put out bear traps for a third night Monday as they try to capture a grizzly bear that killed a woman who was traveling alone on a forest trail near Yellowstone National Park.

Amie Adamson, 48, Derby, Kansas, died in Saturday's fatal mauling near the Montana-Idaho border, the Gallatin County Coroner's Office said. The victim was a marathon runner, and officials said she was likely running or walking at the time of the attack.

Officials ruled out a rare predatory attack, which suggests Adamson instead died following a chance bear encounter as she traveled by herself in a wooded area frequented by grizzly and black bears.

She was killed a few hundred yards (meters) from a trailhead and a private campground and RV park, said Morgan Jacobsen with Montana Fish, Wildlife and Parks. The bear was travelling with one or more cubs, and there were no indications that it tried to eat the victim.

Authorities have not decided whether they would kill the adult bear if it’s captured or whether they would relocate it, Jacobsen said.

Adamson is a former English teacher who left the classroom in 2015 to backpack across much of the U.S. and later wrote a book, "Walking Out," about her career and experiences.

The victim's mother described her as a hiker, marathon runner and "just a beautiful free spirit." KWCH-TV in Wichita reported.

"She lived for experiences," Janet Adamson said, adding that her daughter did not care about material possessions and died "doing what she loved."

A hiker found her body around 8 a.m. Saturday. The cause of death was excessive blood loss caused by a bear mauling, the coroner’s office said.

Adamson was wearing running shoes and did not have bear spray, a deterrent that wildlife experts recommend people carry in areas frequented by bears, Jacobsen said.

She had been working nearby and often ran or walked on the trail in the early morning, according to officials and local residents.

"This person was likely out for a morning jog along the trail, and that's when this happened," said Jacobsen.

Tracks of a grizzly bear and at least one cub were found at the scene of the attack, which occurred near the Buttermilk Trailhead 8 miles west of West Yellowstone, a busy summer tourist town and gateway to the national park.

The trail is used by hikers, horseback riders and people in off-road vehicles.

Rangers issued an emergency closure for areas of the Custer Gallatin National Forest. It did not include Yellowstone National Park.

Local resident Bill Youngwirth said people in the area were aware of the mauling and the forest closure, but they weren't panicked over the attack because the bear could have struck out defensively after being surprised when the victim came around a corner.

The attack happened about a mile from several vacation homes that Youngwirth rents adjacent to the forest.

"I tell everybody, ‘Better take bear spray and know how to use it,’" he said. "And the big thing is, don't go alone."

A trail camera captured an image of a grizzly bear with two cubs in the area on Saturday night. There have been no sightings since, Jacobsen said. Traps set for the bears on Saturday and Sunday nights came up empty, and attempts to locate the bears from an aircraft were unsuccessful.

As time goes by, he added, trapping becomes less effective as chances increase of catching a bear that wasn’t involved in the attack.

Laura Skinner, who co-owns West Yellowstone Rodeo and Creek Side Trail Rides, said the attack did not interrupt its horseback rides on private property or its nightly rodeos.

"We have bears all the time. The only precaution we’re taking is we’re checking trails. We send a rider out first to check to make sure there’s nothing there," she said.

"I’m pretty sure with all the activity with them tracking it and trying to hunt it down, it’s probably nowhere near here," she added.

Grizzly bear populations in the northern U.S. Rocky Mountains grew significantly over the past several and the animals in recent years have been showing up in places they hadn't been seen for generations. Since 2010, grizzlies in and around Yellowstone have killed at least nine people. Attacks remain relatively rare in the region, which draws several million tourists each summer.

A backcountry guide was killed near West Yellowstone two years ago when he was mauled by a large grizzly bear that wildlife officials said was probably defending a nearby moose carcass. And a hiker was killed north of Yellowstone park last year in a suspected grizzly encounter in a remote area of the Absaroka Mountains south of Livingston, Montana.

Encounters with humans can prove deadly for bears, too: A five-year-old female grizzly in Glacier National Park was euthanized last week after officials said it got used to eating food from campgrounds and was becoming increasingly aggressive.

Grizzlies are protected under federal law outside of Alaska. Elected officials in the Yellowstone region are pushing to lift protections and allow grizzly hunting.

State officials last week warned visitors and residents of grizzly bear sightings throughout the state, "particularly in areas between the Northern Continental Divide and the Greater Yellowstone ecosystems."

They implored those camping and visiting parks to carry bear spray, store their food while outside and tend to their garbage.

President Biden's dog Commander — the nearly two and a half year old German shepherd who replaced former first dog Major over aggressive behavior — bit seven people in a four-month period, according to a new report.

One of the more serious incidents involving Commander, according to internal Secret Service communications first reported by the New York Post, led to the White House physician's office referring a Secret Service officer to the hospital for treatment on Nov. 3, 2022, after the individual was bitten by the dog on the thigh and arm.

Other emails released under the Freedom of Information Act to conservative legal group Judicial Watch revealed that Commander had broken the skin of another Secret Service member's hand and arm just weeks later, after Biden removed his leash outside the White House following a family movie night. In January, Commander bit and "latched on" to a security technician's back at Biden's home in Wilmington, Delaware.

"These shocking records raise fundamental questions about President Biden and the Secret Service," said Judicial Watch President Tom Fitton, according to the outlet. "This is a special sort of craziness and corruption where a president would allow his dog to repeatedly attack and bite Secret Service and White House personnel. And rather than protect its agents, the Secret Service tried to illegally hide documents about the abuse of its agents and officers by the Biden family."

BIDEN'S DOG, MAJOR, BIT SECRET SERVICE MEMBERS FOR 8 DAYS IN A ROW, EMAIL SAYS

In October 2022, a Secret Service officer emailed colleagues warning that it was only a matter of time before the Biden's canine pet bit an officer. "Commander has been exhibiting extremely aggressive behavior," the officer wrote on Oct. 26.

The most serious incident involving Commander occurred on Nov. 3, 2022, when a Secret Service officer was seated at the bottom of a stairwell at the White House.

The dog "came down the stairs and walked toward" the officer, according to an internal agency email, before he bit the officer’s arm on the tricep area. When the officer stood up, Commander bit down on the quad muscle area of the officer's the leg.

One officer stated that the attack victim reported "a considerable amount of pain" and used a steel cart to shield himself from the dog's attack.

Two days after the incident took place, the officer who was attacked emailed a colleague who asked about their recovery, writing, "My leg and arm still hurts. He bit me twice and ran at me twice."

The inquiring colleague responded, "What a joke… if it wasn’t their dog he would already have been put down – freaking clown needs a muzzle."

Several other incidents involving Commander were also noted in the report highlighting the emails, including some that directly involved members of the first family.

While first lady Jill Biden walked Commander in the Kennedy Garden near the East Wing of the White House, the dog bit a Secret Service uniformed officer on the left high, causing "bruising, tenderness and pain in the bite area," according to communications reported by the New York Post.

Four days later, on Nov. 14, another officer noted in an email that he had to defend himself from the dog with a chair.

The officer said he "heard the dog bark with a loud aggressive sound" and "looked up and saw him at the landing of the ushers staircase. I made eye contact with him and grabbed the black chair I was sitting on and held it in front of me while backing up."

BIDEN'S DOG MAJOR BITES ANOTHER WHITE HOUSE EMPLOYEE

"For the past several Presidential administrations, the Secret Services has navigated how to best operate around family pets and these incidents are no exception. We take the safety and wellbeing of our employees extremely seriously," Anthony Guglielmi, U.S. Secret Service chief of communications said in a statement to Fox. 

"Agency employees are encouraged to report any job-related injuries to their immediate supervisors for appropriate documentation. As such, we are aware of past incidents involving first-family pets and these instances were treated similarly to comparable workplace injuries, to include with relevant notifications and reporting procedures followed. While special agents and officers neither care for nor handle the first family’s pets, we continuously work with all applicable entities to minimize adverse impacts in an environment that includes pets," Guglielmi said.

Following The Post's report, Elizabeth Alexander, who serves as communications director for the first lady, told Fox that the Bidens are working on "additional leashing protocols and training" for Commander.

"The White House complex is a unique and often stressful environment for family pets, and the First Family is working through ways to make this situation better for everyone. They have been partnering with the Secret Service and Executive Residence staff on additional leashing protocols and training, as well as establishing designated areas for Commander to run and exercise," Alexander said. "According to the Secret Service, each incident referenced was treated similarly to comparable workplace injuries, with relevant notifications and reporting procedures followed. The President and First Lady are incredibly grateful to the Secret Service and Executive Residence staff for all they do to keep them, their family, and the country safe."

The string of attacks from Commander — ranging from September 2022 to January 2023 — came after Biden's former dog, Major, was ousted from the White House over similar behavior.

In early 2021, shortly after Biden's tenure in the White House started, Major bit someone at the White House, causing a "minor injury," then-White House press secretary Jen Psaki confirmed to reporters. Major was subsequently sent to live at Biden's Delaware home before he returned.

Two weeks after the incident, Biden announced Major would be returning to the White House, insisting that "he's a sweet dog" and that "85% of the people there love him."

Upon his return, Major was involved in another incident involving a White House employee who sought medical attention. The encounter took place on the White House South Lawn. CNN first reported the bite, adding that the employee worked for the National Park Service. 

First Lady Jill Biden’s then-press secretary Michael de Rosa confirmed the dog had "nipped" someone in a statement to Fox News at the time, saying "Major is still adjusting to his new surroundings and he nipped someone while on a walk. Out of an abundance of caution, the individual was seen by WHMU and then returned to work without injury."

The Post reported in August 2021 that Major had "attacked many more people than the White House has disclosed," with the outlet noting that he "bit members of the Secret Service eight days in a row in early March — though only one such incident was publicly acknowledged."

The outlet, based on emails released by Judicial Watch, noted that at least one visitor at the White House was bitten in March 2021.

"We’re sure Major is a good dog but these records show he was involved in many more biting incidents than the Biden White House has publicly acknowledged," Fitton said at the time. "It is disturbing to see a White House cover-up of numerous injuries to Secret Service and White House personnel by the Bidens’ family pet."

Major was later relocated from the White House to reportedly be cared for by friends of the Biden family.

It is unclear whether Commander has been involved in any other incident since January 2023 or upon his arrival to the White House, which came nine months prior to the first documented incident in the emails revealed Tuesday.
