Mountain Lion Attack on Colorado Trail Raises Fatality Concerns

At a Glance

  • Woman’s body found on a Colorado trail shows mountain lion wounds, the fourth fatal attack in North America this decade.
  • Hiker Gary Messina survived a November lion attack on the same trail.
  • Authorities have killed two lions and are hunting a third.

Why it matters: The incident highlights the growing overlap between human recreation and mountain lion habitats in Colorado.

On New Year’s Day, a woman’s body was discovered on the Crosier Mountain trail in Colorado, and her injuries point to a mountain lion attack, marking the fourth fatal encounter in North America this decade. The same trail had already seen a harrowing encounter last November when hiker Gary Messina, a 32-year-old from Glen Haven, fought off a lion.

Recent Lion Encounters

Messina recounted seeing two glowing eyes in the brush and then being pursued. He threw his phone, kicked dirt, and finally struck the animal with a broken stick, forcing it to flee.

Investigation and Wildlife Response

Wildlife officials tracked down and killed two lions near the site, one at the scene and another nearby. A necropsy will determine if either attacked the woman or carried diseases such as rabies or avian flu.
