A Billings man has been identified as the victim of a grizzly bear attack last week.

63-year-old Lance Crosby was found dead last Friday in an off-trail area in the Lake Village area in Yellowstone National Park.

The investigation concluded that Crosby was attacked by one lone grizzly bear. According to a YNP press release:

His body was found partially consumed and cached, or covered, and partial tracks at the scene indicate that an adult female grizzly and at least one cub-of-the-year were present and likely involved in the attack. While the exact cause of death has not been determined, investigators have identified what appear to be defensive wounds on Crosby’s forearms. DNA evidence was recovered at the scene and will be used to help identify the bear/s involved. A forensic autopsy is scheduled for later today.

Yellowstone wildlife biologists set traps Friday evening, wherein one bear was captured later that same evening, but no other bears have been captured to date. If this grizzly bear is found to be the one that attacked Crosby, it will be euthanized.

"The decision to euthanize a bear is one that we do not take lightly. As park managers, we are constantly working to strike a balance between the preservation of park resources and the safety of our park visitors and employees," said Yellowstone Superintendent Dan Wenk. "Our decision is based on the totality of the circumstances in this unfortunate event. Yellowstone has had a grizzly bear management program since 1983. The primary goals of this program are to minimize bear-human interactions, prevent human-caused displacement of bears from prime food sources, and to decrease the risk of bear-caused human injuries."

Officials want to remind tourists that no matter the experience level, hikers are advised to stay on designated trails, carry bear spray and be alert at all times while travelling through the park.
