Police in Burlington, Vermont, say they are "hopeful" that they'll find a 21-year-old university student who disappeared late last week.
Police say they're focusing on one particular lead, but volunteer searchers will be joining FBI agents and National Guard personnel in a continuing search for clues.
Michelle Gardner-Quinn of Arlington, Virginia, hasn't been seen since she left downtown Burlington to walk to her dorm early Saturday. The police chief says she was socializing with friends, but "there's no indication she was inebriated."
In a video plea on the Internet, Gardner-Quinn's parents are begging anyone who knows anything about the disappearance to tell them "instantly."
