A woman's death on a trail is being investigated as a suspected deadly mountain lion attack, according to Colorado Parks and Wildlife.

A solo hiker who authorities believe was killed by a mountain lion on a remote Colorado trail on New Year's Day was not the first person to encounter a big cat in the area in recent weeks.

Gary Messina said he was running along the same trail on a dark November morning when his headlamp caught the gleam of two eyes in the nearby brush.
