The family of a missing park ranger tells reporters they believe he's injured.
Thirty-one-year-old Jeff Christensen has been missing since last Friday, when he disappeared in Colorado's Rocky Mountain National Park. His mother, Chris, says her son is good with maps, and that he would've walked out by now if he wasn't hurt.
More than 125 people, dog teams and a handful of helicopters are searching for Christensen in a 26-square-mile area of the Mummy Range.
Elevations in the search area range from 10,600 feet to 13,000 feet.
Park officials say Christensen has been a ranger for four seasons, and had a radio and backpack equipped with various gear -- even though he hadn't planned to spend the night in the park.
