On April 15, just days before Aubrey Sacco went missing in Nepal, she was having the time of her life traveling through India. She wrote that colorful, just-washed clothing had been lain out like a rainbow. The smell of coffee, she noted, mixed with the scents of curries, chai, and bathroom smells were a reminder that "yes, I am in India," she wrote on her blog, "Glitter the World: Spreading the Sparkle One Country at a Time." Five days later, Sacco, a University of Colorado graduate from Greeley, sent an e-mail to her father, Paul Sacco, who says his daughter began a roughly 10-day trek into the Langtang valley north of Kathmandu. Now Paul Sacco is headed there with men from Colorado to help find his 23-year-old daughter, who was expected to check in April 29 and has been missing ever since, according to CNN. The embassy, Nepali authorities, and ordinary people in the country who the family contacted through word of mouth have all helped, Paul Sacco says, but he wants to be there himself. "I want people to see me and know more about my daughter, and feel the urgency that we need to have to search for her," Sacco says. "I understand, from talking with world travelers and others that nothing substitutes for being there (during a search)." Joining Sacco is his son and a Nepali man from Colorado, linked to the family through a friend, who will serve as translator and guide. Sacco worries that Maoist protests that disrupted business in Kathmandu during the first week of May might have prevented his daughter from finding a bus, forcing her to hike further. Paul Sacco is nearly 60 and just had hip surgery, but he says he'll walk national park trails to retrace his daughter's steps, according to the Greeley Tribune.
