Traps set for grizzly bear that killed woman near Yellowstone National Park

Billings, Montana — 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, of Derby, Kansas, died in Saturday's 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.
