Prosecutors say Christensen lured Zhang into his car in June 2017, tortured and killed her. Her body hasn't been found. Urbana attorney Steve Beckett, who represents Zhang's family, says he is shocked by the mental-health defense withdrawal.
Prosecutors have asked the court if their own mental health expert can still examine Christensen. Christensen's trial is set to begin June 3.
