(Urbana, IL) — The suspect in the disappearance of a University of Illinois scholar is once again pleading not guilty. Brendt Christensen yesterday pleaded not guilty to a new set of kidnapping charges. Investigators say he lured Yingying Zhang into his car on the U of I campus last month. Police think Zhang is dead, but Christensen is only charged with her kidnapping. The new charges are from a grand jury indictment earlier this month. Christensen’s trial is tentatively set for September.
