Wearing jeans, black shoes, a brown cap, denim jacket and blue cardigan, the 24 year-old was pictured this week visiting an unnamed office building in downtown Seattle.
She appeared in a pensive mood, in contrast to other pictures that emerged of her smiling with an unidentified friend while carrying chocolate and toothpaste.
The pictures are some of the first to emerge since her acquittal for the 2007 murder in Perugia of her British flatmate, who was stabbed to death in the home they shared in the Italian city.
Miss Knox made a tearful return home on Wednesday to Seattle, where she has largely been viewed as an innocent girl trapped abroad in an archaic justice system.
Her father had suggested she had left Seattle, but it appears she was staying in a house not far from the homes of her divorced parents. Local media have reportedly agreed to give the family their privacy.
