The defence and prosecution in Xiang's trial agreed that he suffered from a paranoid delusional disorder. The prosecution asked the jury to find him not guilty. On 17 June 2004 the Victorian Supreme Court jury found him not guilty of the murder of Wu and Chan and of the attempted murder of five other people in the tutorial room due to mental impairment. Justice Bernard Teague ordered Xiang be transferred to the Thomas Embling psychiatric hospital. He may be held there for as long as 25 years.
