Ammon News - A woman has died in a rare suspected mountain lion attack in Colorado on Thursday, officials said.

Hikers told authorities they saw a mountain lion near a person who was lying on the ground 100 yards away around 12:15 p.m., on the Crosier Mountain trail in unincorporated Larimer County, Colorado Parks and Wildlife said in a news release.

The hikers scared the lion away by throwing rocks and then attended to the adult woman, the release said. One of the witnesses was a physician and "did not find a pulse," said Kara Van Hoose, spokesperson with Colorado Parks and Wildlife.

The victim’s identity and cause of death will be released by the Larimer County Coroner.

Colorado Parks and Wildlife is investigating the death as a suspected mountain lion attack.
