The FBI has made an arrest in the Yingying Zhang case, and the agency believes that the 26-year-old University of Illinois visiting scholar from China is dead. The FBI said in a news release that agents arrested 27-year-old Brendt Christensen of Champaign, a former University of Illinois graduate student, on Friday.

While the search for missing University of Illinois scholar Yingying Zhang closes its third week, University of Illinois officials say about 350 people marched through campus Thursday night and gathered for a concert by a group of Chinese students.

26-year-old Yingying Zhang, a visiting scholar at the University of Illinois, was last seen Friday afternoon getting into a black Saturn Astra on North Goodwin Ave. in Urbana.

University of Illinois police say they've received many responses to their request for information in the case of a visiting scholar from China who has been missing since Friday. Security camera video shows 26-year-old Yingying Zhang climbing into a car on campus and then being driven away. Friends and family have not heard from her since.

Champaign Police are waiting for an autopsy to tell them whether human remains recovered Sunday from Clinton Lake are that of Ashley Chemere Gibson.
