ESTES PARK - Authorities asked for the public's help in finding a missing exchange student Thursday. Twenty-year-old Pratistha Budhathoki was last seen leaving for work on June 18 at around 9:30 a.m. However, she never arrived at work. "She was like, 'Oh, I'm late for work, I better hurry,'" said Smriti Pande, Budhathoki's roommate. She is described as 5 feet 3 inches tall, 130 pounds, with black hair and brown eyes. Budhathoki was last seen wearing a "Muchin' House" shirt. She is an exchange student from Nepal. Estes Park Police say witnesses told them Budhathoki only associated with a small group of other exchange students. Witnesses say it is very uncharacteristic for her to disappear. "We're really surprised," said Commander Kes Kufeld with Estes Park Police. "It's just totally unlike her. It's uncharacteristic of her." Her friend, Aswin Penday said, "It's just hard on everybody." "She's the kind of person if she goes somewhere, she'll call us," said Penday. Anyone with information is urged to contact the Estes Park Police Department at 970-577-3827.
