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.
- Throwing the phone at the animal
- Kicking dirt and yelling

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.
Kara Van Hoose stated:
> “Wounds consistent with a mountain lion attack.”

Rafael Moreno said:
> “An autopsy is scheduled for next week.”
Kara Van Hoose added:
> “We are still searching for a third mountain lion, and nearby trails remain closed while the hunt continues.”
