(Urbana, IL) — Court documents are providing a glimpse into the evidence against the man accused of kidnapping and killing a Chinese-born U of I scholar. WCIA-TV reported on the documents over the weekend. They include FBI reports that say investigators found possible matches to Yingying Zhang’s blood in Brendt Christensen’s bedroom and bathroom. The documents also say a cadaver dog indicated that a body was in Christensen’s apartment. Christensen’s lawyers are trying to challenge the reports.
