The Latest: Professor saw no signs of trouble with suspect

CHICAGO (AP) - The Latest on the disappearance of a missing University of Illinois scholar from China: (all times local):

2:30 p.m.

A University of Illinois physics professor and graduate student adviser says he saw no signs that a 28-year-old former student charged with kidnapping a visiting Chinese scholar was acting unusually.

Professor Lance Cooper said Saturday that Brendt Christensen was accepted into the highly competitive physics program in 2013. The Champaign, Illinois, man intended to get his Ph.D., but told Cooper in 2016 he’d decided not to do so. He continued teaching as a graduate assistant and earned his master’s degree in mid-May.

Christensen was charged Friday with kidnapping 26-year-old Yingying Zhang. She disappeared on June 9. Authorities say they believe she is dead, though her body hasn’t been found.

Cooper says there are many ways he would have been notified if Christensen was acting differently or having problems. He says “None of those flags were raised.”

Christensen was charged Friday with kidnapping 26-year-old Yingying Zhang, who went missing June 9. Authorities now believe Zhang is dead, though they say her body has not been found.

Twenty-eight-year-old Brendt Christensen of Champaign is scheduled to appear in court Monday in Urbana.

Yingying Zhang, the 26-year-old daughter of a working-class factory driver from China, disappeared on June 9, just weeks after arriving at the Urbana-Champaign campus in central Illinois where was doing research in agricultural sciences. She was expected to begin work on her doctorate in the fall.

Zhang’s disappearance fed anxieties of families of Chinese students studying in the U.S.

Authorities declined comment when asked if they had any leads on where Zhang’s body might be located.
