Police: Missing woman's phone was used days after she disappeared ESTES PARK, Colo. — Someone used a cell phone belonging to a missing exchange student two days after she was last seen, but investigators said Monday they had no other clues and did not know where she was. Pratistha Budhathoki, 20, of Nepal was working in this town near Rocky Mountain National Park for the summer to help pay for her studies at St. Cloud State University in Minnesota, police said. She was last seen when she left for work on June 18, but she did not arrive at her job, police Cmdr. Wes Kufeld said. http://www.gjsentinel.com/news/content/gen/ap/CO_Missing_Woman.html Kufeld said someone used Budhathoki's cell phone in Denver at 8:26 a.m. June 20 to check her voice mail. He said investigators checked with airlines at Denver International Airport but no one recalled seeing her. Kufeld said investigators also checked with hospitals around the state with no luck. He said Estes Park has 17 sworn officers and all are working on the case. Estes Park is about 50 miles northwest of Denver. An uncle of Budhathoki's is trying to travel to Estes Park but has been unable to leave Nepal because of visa problems, Kufeld said. Police have said Budhathoki does not own a car and left her passport at home. She was not a hiker or mountain biker, police said. ___ June 26, 2006 - 2:55 p.m. PDT
