Chan was a retired annuitant who had returned to the school to work in international student registration. Dunn would not provide a motive in the killing, only to say that Vo acted alone in planning the crime.

Fullerton police Lt. Jon Radus said Thursday that investigators "are confident" the backpack belonged to Vo.

Vo is being held in Orange County Jail without bail. His first court appearance is scheduled for Friday.
