About 350 people gathered Thursday night, June 29, 2017, to show support for missing University of Illinois visiting scholar Yingying Zhang, including an unlikely participant — Brendt Christensen, the man charged with kidnapping in her June 9 disappearance. Christensen, 28, a former UI physics graduate student, attended the event outside Krannert Center for the Performing Arts even as he was under surveillance by authorities, The News-Gazette learned Saturday (first photo in the gallery). He was arrested the next night.
